                GLU (OpenGL Utility) binding for .NET, implementing GLU 1.3.

                <para>
                    Binds functions and definitions in glu32.dll or libGLU.so.

                    The OpenGL Utility (GLU) library contains several groups of functions that
                    complement the core OpenGL interface by providing support for auxiliary features.
                    These features include: mipmapping, matrix manipulation, polygon tessellation,
                    quadrics, NURBS, and error handling.
                </para>
                <para>
                    Mipmapping routines include image scaling and automatic mipmap generation.  A
                    variety of matrix manipulation functions build projection and viewing matrices,
                    or project vertices from one coordinate system to another.  Polygon tessellation
                    routines convert concave polygons into triangles for easy rendering.  Quadrics
                    support renders a few basic quadrics such as spheres and cones.  NURBS code maps
                    complicated NURBS curves and trimmed surfaces into simpler OpenGL evaluators.
                    Lastly, an error lookup routine translates OpenGL and GLU error codes into
                    strings.  GLU library routines may call OpenGL library routines.  Thus, an OpenGL
                    context should be made current before calling any GLU functions.  Otherwise an
                    OpenGL error may occur.
                </para>
                <para>
                    These utility functions make use of core OpenGL functions, so any OpenGL
                    implementation is guaranteed to support the utility functions.

                    The definition for a NURBS surface can contain many trimming loops.  For
                    example, if you wrote a definition for a NURBS surface that resembled a
                    rectangle with a hole punched out, the definition would contain two trimming
                    loops.  One loop would define the outer edge of the rectangle; the other
                    would define the hole punched out of the rectangle.  The definitions of each

                    The definition of a single closed trimming loop can consist of multiple curve
                    segments, each described as a piecewise linear curve (see
                    <see cref="M:Tao.OpenGl.Glu.gluPwlCurve(Tao.OpenGl.Glu.GLUnurbs,System.Int32,System.Single[],System.Int32,System.Int32)"/>) or as a single NURBS curve (see

                    only library calls that can appear in a trimming loop definition (between the
                    calls to <b>gluBeginTrim</b> and <see cref="M:Tao.OpenGl.Glu.gluEndTrim(Tao.OpenGl.Glu.GLUnurbs)"/>) are

                    The area of the NURBS surface that is displayed is the region in the domain
                    to the left of the trimming curve as the curve parameter increases.  Thus,
                    the retained region of the NURBS surface is inside a counterclockwise
                    trimming loop and outside a clockwise trimming loop.  For the rectangle
                    mentioned earlier, the trimming loop for the outer edge of the rectangle runs
                    counterclockwise, while the trimming loop for the punched-out hole runs
                    clockwise.

                <para>
                    If you use more than one curve to define a single trimming loop, the curve
                    segments must form a closed loop (that is, the endpoint of each curve must be
                    the starting point of the next curve, and the endpoint of the final curve
                    must be the starting point of the first curve).  If the endpoints of the
                    curve are sufficiently close together but not exactly coincident, they will
                    be coerced to match.  If the endpoints are not sufficiently close, an error
                    results (see <see cref="M:Tao.OpenGl.Glu.gluNurbsCallback(Tao.OpenGl.Glu.GLUnurbs,System.Int32,Tao.OpenGl.Glu.NurbsBeginCallback)"/>).

                <para>
                    If a trimming loop definition contains multiple curves, the direction of the
                    curves must be consistent (that is, the inside must be to the left of all of
                    the curves).  Nested trimming loops are legal as long as the curve
                    orientations alternate correctly.  If trimming curves are self-intersecting,
                    or intersect one another, an error results.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating data in half until size 1×1 is reached.  At each level, each texel
                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a

                    levels are possible: 16×1, 8×1, 4×1, 2×1, 1×1.  These correspond to levels 2
                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by

                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a

                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by

                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger

                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by

                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger

                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load

                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by

                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger

                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than
                    the highest mipmap level which is, in this case, 6.

                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a
                    GLU error code is returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is
                    loaded.

                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16, the following
                    levels are possible: 16×1, 8×1, 4×1, 2×1, 1×1.  These correspond to levels 2
                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than
                    the highest mipmap level which is, in this case, 6.
                </para>
                <para>
                    The highest mipmap level can be derived from the formula

                    texture maps of decreasing resolutions called a mipmap.  This is used for the
                    antialiasing of texture mapped primitives.

                    A return value of zero indicates success, otherwise a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>).

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating data in half until size 1×1 is reached.  At each level, each texel
                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a
                    GLU error code is returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is
                    loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16, the following
                    levels are possible: 16×1, 8×1, 4×1, 2×1, 1×1.  These correspond to levels 2
                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than
                    the highest mipmap level which is, in this case, 6.

                    The highest mipmap level can be derived from the formula

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating data in half until size 1×1 is reached.  At each level, each texel
                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a
                    GLU error code is returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, the following
                    levels are possible: 16×1, 8×1, 4×1, 2×1, 1×1.  These correspond to levels 2
                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than
                    the highest mipmap level which is, in this case, 6.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating data in half until size 1×1 is reached.  At each level, each texel
                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a
                    GLU error code is returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, the following
                    levels are possible: 16×1, 8×1, 4×1, 2×1, 1×1.  These correspond to levels 2
                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than
                    the highest mipmap level which is, in this case, 6.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating data in half until size 1×1 is reached.  At each level, each texel
                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a
                    GLU error code is returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, the following
                    levels are possible: 16×1, 8×1, 4×1, 2×1, 1×1.  These correspond to levels 2
                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than
                    the highest mipmap level which is, in this case, 6.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating data in half until size 1×1 is reached.  At each level, each texel
                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a
                    GLU error code is returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is

                    levels are possible: 16×1, 8×1, 4×1, 2×1, 1×1.  These correspond to levels 2
                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating data in half until size 1×1 is reached.  At each level, each texel
                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a

                    levels are possible: 16×1, 8×1, 4×1, 2×1, 1×1.  These correspond to levels 2
                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating data in half until size 1×1 is reached.  At each level, each texel
                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a

                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by

                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a

                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating data in half until size 1×1 is reached.  At each level, each texel
                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a

                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating data in half until size 1×1 is reached.  At each level, each texel
                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a

                    levels are possible: 16×1, 8×1, 4×1, 2×1, 1×1.  These correspond to levels 2
                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating data in half until size 1×1 is reached.  At each level, each texel
                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a

                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating data in half until size 1×1 is reached.  At each level, each texel
                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a
                    GLU error code is returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, the following
                    levels are possible: 16×1, 8×1, 4×1, 2×1, 1×1.  These correspond to levels 2
                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than
                    the highest mipmap level which is, in this case, 6.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by

                    in the halved mipmap level is an average of the corresponding two texels in
                    the larger mipmap level.  <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load
                    these mipmap levels from <i>min</i> to <i>max</i>.  If <i>max</i> is larger
                    than the highest mipmap level for the texture of the specified size, then a

                    through 6 respectively.  If <i>min</i> is 3 and <i>max</i> is 5, then only
                    mipmap levels 8×1, 4×1 and 2×1 are loaded.  However, if <i>max</i> is 7 then
                    an error is returned and nothing is loaded since <i>max</i> is larger than

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, width
                    is continually halved until it fits.
                </para>
                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,
                    2×1 and 1×1.  These correspond to levels 0 through 6, respectively.

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.
                </para>

                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, width
                    is continually halved until it fits.
                </para>
                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,
                    2×1 and 1×1.  These correspond to levels 0 through 6, respectively.

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, width
                    is continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,
                    2×1 and 1×1.  These correspond to levels 0 through 6, respectively.

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.
                </para>

                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, width
                    is continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,
                    2×1 and 1×1.  These correspond to levels 0 through 6, respectively.

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.
                </para>

                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, width
                    is continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.
                </para>

                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, width
                    is continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.

                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, width
                    is continually halved until it fits.
                </para>
                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,
                    2×1 and 1×1.  These correspond to levels 0 through 6, respectively.

                    query for the width actually used at level 0.  (The width may not be equal to

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.

                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.

                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.

                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.

                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,

                    derived indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First,
                    query for the width actually used at level 0.  (The width may not be equal to
                    <i>width</i> since proxy textures might have scaled it to fit the
                    implementation.)  Then the maximum level can be derived from the formula

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.

                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>

                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    Note that there is no direct way of querying the maximum level.  This can be
                    derived indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First,
                    query for the width actually used at level 0.  (The width may not be equal to
                    <i>width</i> since proxy textures might have scaled it to fit the
                    implementation.)  Then the maximum level can be derived from the formula

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.

                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>

                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,

                    Note that there is no direct way of querying the maximum level.  This can be
                    derived indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First,
                    query for the width actually used at level 0.  (The width may not be equal to
                    <i>width</i> since proxy textures might have scaled it to fit the

                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,
                    2×1 and 1×1.  These correspond to levels 0 through 6, respectively.

                    Note that there is no direct way of querying the maximum level.  This can be
                    derived indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First,
                    query for the width actually used at level 0.  (The width may not be equal to
                    <i>width</i> since proxy textures might have scaled it to fit the

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.

                    determine if the implementation can fit the requested texture.  If not, width
                    is continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved

                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    is a copy of <i>data</i>.  The highest level is <c>log2(width)</c>.  For
                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,
                    2×1 and 1×1.  These correspond to levels 0 through 6, respectively.

                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    is a copy of <i>data</i>.  The highest level is <c>log2(width)</c>.  For
                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,
                    2×1 and 1×1.  These correspond to levels 0 through 6, respectively.

                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.

                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                    is a copy of <i>data</i>.  The highest level is <c>log2(width)</c>.  For
                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,
                    2×1 and 1×1.  These correspond to levels 0 through 6, respectively.

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, width
                    is continually halved until it fits.
                </para>
                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                <para>
                    <b>glTexImage1D</b> is called to load each of these mipmap levels.  Level 0
                    is a copy of <i>data</i>.  The highest level is <c>log2(width)</c>.  For
                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,
                    2×1 and 1×1.  These correspond to levels 0 through 6, respectively.

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, width
                    is continually halved until it fits.
                </para>
                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                <para>
                    <b>glTexImage1D</b> is called to load each of these mipmap levels.  Level 0
                    is a copy of <i>data</i>.  The highest level is <c>log2(width)</c>.  For
                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,
                    2×1 and 1×1.  These correspond to levels 0 through 6, respectively.

                    texture maps of decreasing resolutions called a mipmap.  This is used for the
                    antialiasing of texture mapped primitives.

                    A return value of zero indicates success, otherwise a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>).

                    Initially, the <i>width</i> of <i>data</i> is checked to see if it is a power
                    of 2.  If not, a copy of <i>data</i> is scaled up or down to the nearest
                    power of 2.  (If <i>width</i> is exactly between powers of 2, then the copy
                    of <i>data</i> will scale upwards.)  This copy will be used for subsequent
                    mipmapping operations described below.  For example, if <i>width</i> is 57
                    then a copy of <i>data</i> will scale up to 64 before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage1D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, width
                    is continually halved until it fits.
                </para>
                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half until size 1×1 is reached.  At each level, each texel in the halved
                    mipmap level is an average of the corresponding two texels in the larger
                    mipmap level.

                <para>
                    <b>glTexImage1D</b> is called to load each of these mipmap levels.  Level 0
                    is a copy of <i>data</i>.  The highest level is <c>log2(width)</c>.  For
                    example, if <i>width</i> is 64 and the implementation can store a texture of
                    this size, the following mipmap levels are built: 64×1, 32×1, 16×1, 8×1, 4×1,
                    2×1 and 1×1.  These correspond to levels 0 through 6, respectively.

                    Note that there is no direct way of querying the maximum level.  This can be

                    query for the width actually used at level 0.  (The width may not be equal to
                    <i>width</i> since proxy textures might have scaled it to fit the
                    implementation.)  Then the maximum level can be derived from the formula

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    The highest mipmap level can be derived from the formula

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    The highest mipmap level can be derived from the formula

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    The highest mipmap level can be derived from the formula

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    The highest mipmap level can be derived from the formula

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from

                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.

                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.

                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    The highest mipmap level can be derived from the formula

                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    The highest mipmap level can be derived from the formula

                    antialiasing of texture mapped primitives.

                    A return value of zero indicates success, otherwise a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>).

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                <para>
                    The highest mipmap level can be derived from the formula

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    The highest mipmap level can be derived from the formula

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    The highest mipmap level can be derived from the formula

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    The highest mipmap level can be derived from the formula

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    The highest mipmap level can be derived from the formula

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from
                    <i>min</i> to <i>max</i>.  If <i>max</i> is larger than the highest mipmap
                    level for the texture of the specified size, then a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16 and <i>height</i> is
                    8, the following levels are possible: 16×8, 8×4, 4×2, 2×1, 1×1.  These
                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                    decimating <i>data</i> in half along both dimensions until size 1×1 is
                    reached.  At each level, each texel in the halved mipmap level is an average
                    of the corresponding four texels in the larger mipmap level.  (In the case of
                    rectangular images, the decimation will ultimately reach an N×1 or 1×N
                    configuration.  Here, two texels are averaged instead.)
                    <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/> is called to load these mipmap levels from

                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.

                    correspond to levels 2 through 6 respectively.  If <i>min</i> is 3 and
                    <i>max</i> is 5, then only mipmap levels 8×4, 4×2 and 2×1 are loaded.
                    However, if <i>max</i> is 7 then an error is returned and nothing is loaded
                    since <i>max</i> is larger than the highest mipmap level which is, in this
                    case, 6.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>

                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is

                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument
                    <see cref="F:Tao.OpenGl.Gl.GL_MAX_TEXTURE_SIZE"/>.)
                </para>
                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument
                    <see cref="F:Tao.OpenGl.Gl.GL_MAX_TEXTURE_SIZE"/>.)

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument
                    <see cref="F:Tao.OpenGl.Gl.GL_MAX_TEXTURE_SIZE"/>.)

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument
                    <see cref="F:Tao.OpenGl.Gl.GL_MAX_TEXTURE_SIZE"/>.)

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument
                    <see cref="F:Tao.OpenGl.Gl.GL_MAX_TEXTURE_SIZE"/>.)

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument
                    <see cref="F:Tao.OpenGl.Gl.GL_MAX_TEXTURE_SIZE"/>.)

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument
                    <see cref="F:Tao.OpenGl.Gl.GL_MAX_TEXTURE_SIZE"/>.)

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument

                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to

                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument

                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    <b>gluBuild2DMipmaps</b> builds a series of prefiltered two-dimensional
                    texture maps of decreasing resolutions called a mipmap.  This is used for
                    the antialiasing of texture-mapped primitives.

                    A return value of zero indicates success, otherwise a GLU error code is
                    returned (see <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>).

                <para>
                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument
                    <see cref="F:Tao.OpenGl.Gl.GL_MAX_TEXTURE_SIZE"/>.)
                </para>
                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)
                </para>

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument
                    <see cref="F:Tao.OpenGl.Gl.GL_MAX_TEXTURE_SIZE"/>.)

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument
                    <see cref="F:Tao.OpenGl.Gl.GL_MAX_TEXTURE_SIZE"/>.)

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived

                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument
                    <see cref="F:Tao.OpenGl.Gl.GL_MAX_TEXTURE_SIZE"/>.)

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument
                    <see cref="F:Tao.OpenGl.Gl.GL_MAX_TEXTURE_SIZE"/>.)

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument
                    <see cref="F:Tao.OpenGl.Gl.GL_MAX_TEXTURE_SIZE"/>.)

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument
                    <see cref="F:Tao.OpenGl.Gl.GL_MAX_TEXTURE_SIZE"/>.)

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                    Initially, the <i>width</i> and <i>height</i> of <i>data</i> are checked to
                    see if they are a power of 2.  If not, a copy of <i>data</i> (not <i>data</i>
                    itself), is scaled up or down to the nearest power of 2.  This copy will be
                    used for subsequent mipmapping operations described below.  (If <i>width</i>
                    or <i>height</i> is exactly between powers of 2, then the copy of <i>data</i>
                    will scale upwards.)  For example, if <i>width</i> is 57 and <i>height</i> is
                    23 then a copy of <i>data</i> will scale up to 64 in <i>width</i> and down to
                    16 in depth, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage2D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, both
                    dimensions are continually halved until it fits.  (If the OpenGL version is
                    &lt;= 1.0, both maximum texture dimensions are clamped to the value returned
                    by <see cref="M:Tao.OpenGl.Gl.glGetIntegerv(System.Int32,System.Int32@)"/> with the argument

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along both dimensions until size 1×1 is reached.  At each level, each
                    texel in the halved mipmap level is an average of the corresponding four
                    texels in the larger mipmap level.  (In the case of rectangular images, the
                    decimation will ultimately reach an N×1 or 1×N configuration.  Here, two
                    texels are averaged instead.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height))</c>.  For example, if <i>width</i> is 64 and
                    <i>height</i> is 16 and the implementation can store a texture of this size,
                    the following mipmap levels are built: 64×16, 32×8, 16×4, 8×2, 4×1, 2×1 and
                    1×1.  These correspond to levels 0 through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width and height actually used at level 0.  (The width and height may not
                    be equal to <i>width</i> and <i>height</i> respectively since proxy textures
                    might have scaled them to fit the implementation.)  Then the maximum level
                    can be derived from the formula <c>log2(max(width,height))</c>.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see
                     <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see
                     <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see
                     <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see
                     <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see
                     <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see
                     <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If

                     specified size, then a GLU error code is returned (see

                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is

                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If

                     specified size, then a GLU error code is returned (see

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see
                     <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.

                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see
                     <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see
                     <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see
                     <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see
                     <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.
                </para>
                <para>
                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see
                     <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If

                     specified size, then a GLU error code is returned (see

                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                     A series of mipmap levels from <i>min</i> to <i>max</i> is built by
                     decimating <i>data</i> in half along both dimensions until size 1×1×1 is
                     reached.  At each level, each texel in the halved mipmap level is an average
                     of the corresponding eight texels in the larger mipmap level.  (If exactly
                     one of the dimensions is 1, four texels are averaged.  If exactly two of the
                     dimensions are 1, two texels are averaged.)  <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>
                     is called to load these mipmap levels from <i>min</i> to <i>max</i>.  If
                     <i>max</i> is larger than the highest mipmap level for the texture of the
                     specified size, then a GLU error code is returned (see
                     <see cref="M:Tao.OpenGl.Glu.gluErrorString(System.Int32)"/>) and nothing is loaded.

                    For example, if <i>level</i> is 2 and <i>width</i> is 16, <i>height</i> is 8
                    and <i>depth</i> is 4, the following levels are possible: 16×8×4, 8×4×2,
                    4×2×1, 2×1×1, 1×1×1.  These correspond to levels 2 through 6 respectively.
                    If <i>min</i> is 3 and <i>max</i> is 5, then only mipmap levels 8×4×2,
                    4×2×1 and 2×1×1 are loaded.  However, if <i>max</i> is 7 then an error is
                    returned and nothing is loaded since <i>max</i> is larger than the highest
                    mipmap level which is, in this case, 6.

                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0
                    through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula
                    <c>log2(max(width,height,depth))</c>.

                    A return value of zero indicates success, otherwise a GLU error code is

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.
                </para>
                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0
                    through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0
                    through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0
                    through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived

                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0
                    through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived

                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.
                </para>
                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0
                    through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula
                    <c>log2(max(width,height,depth))</c>.

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0
                    through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived

                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0

                    There is no direct way of querying the maximum level.  This can be derived

                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all

                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0

                    There is no direct way of querying the maximum level.  This can be derived

                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0
                    through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula
                    <c>log2(max(width,height,depth))</c>.

                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.

                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula
                    <c>log2(max(width,height,depth))</c>.

                    <b>gluBuild3DMipmaps</b> builds a series of prefiltered three-dimensional

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.
                </para>
                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0
                    through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula
                    <c>log2(max(width,height,depth))</c>.

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0

                    There is no direct way of querying the maximum level.  This can be derived

                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0
                    through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived

                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0
                    through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula
                    <c>log2(max(width,height,depth))</c>.

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.
                </para>
                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0
                    through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0

                    There is no direct way of querying the maximum level.  This can be derived

                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all

                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula
                    <c>log2(max(width,height,depth))</c>.

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if

                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>

                    Level 0 is a copy of <i>data</i>.  The highest level is

                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula
                    <c>log2(max(width,height,depth))</c>.

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.
                </para>
                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0
                    through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.
                </para>
                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0
                    through 6, respectively.

                    There is no direct way of querying the maximum level.  This can be derived
                    indirectly via <see cref="M:Tao.OpenGl.Gl.glGetTexLevelParameteriv(System.Int32,System.Int32,System.Int32,System.Int32@)"/>.  First, query for
                    the width, height and depth actually used at level 0.  (The width, height
                    and depth may not be equal to <i>width</i>, <i>height</i> and <i>depth</i>
                    respectively since proxy textures might have scaled them to fit the
                    implementation.)  Then the maximum level can be derived from the formula

                    Initially, the <i>width</i>, <i>height</i> and <i>depth</i> of <i>data</i>
                    are checked to see if they are a power of two.  If not, a copy of <i>data</i>
                    (not <i>data</i> itself), is scaled up or down to the nearest power of two.
                    This copy will be used for subsequent mipmapping operations described below.
                    (If <i>width</i>, <i>height</i> or <i>depth</i> is exactly between powers of
                    2, then the copy of <i>data</i> will scale upwards.)  For example, if
                    <i>width</i> is 57, <i>height</i> is 23 and <i>depth</i> is 24 then a copy of
                    <i>data</i> will scale up to 64 in <i>width</i>, down to 16 in <i>height</i>
                    and up to 32 in <i>depth</i>, before mipmapping takes place.
                </para>
                <para>
                    Then, proxy textures (see <see cref="M:Tao.OpenGl.Gl.glTexImage3D(System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Int32,System.Boolean[])"/>) are used to
                    determine if the implementation can fit the requested texture.  If not, all
                    three dimensions are continually halved until it fits.

                <para>
                    Next, a series of mipmap levels is built by decimating a copy of <i>data</i>
                    in half along all three dimensions until size 1×1×1 is reached.  At each
                    level, each texel in the halved mipmap level is an average of the
                    corresponding eight texels in the larger mipmap level.  (If exactly one of
                    the dimensions is 1, four texels are averaged.  If exactly two of the
                    dimensions are 1, two texels are averaged.)

                    Level 0 is a copy of <i>data</i>.  The highest level is
                    <c>log2(max(width,height,depth))</c>.  For example, if <i>width</i> is 64,
                    <i>height</i> is 16 and <i>depth</i> is 32, and the implementation can store
                    a texture of this size, the following mipmap levels are built: 64×16×32,
                    32×8×16, 16×4×8, 8×2×4, 4×1×2, 2×1×1 and 1×1×1.  These correspond to levels 0

                    respectively since proxy textures might have scaled them to fit the

                    set of oriented curve segments (forming a closed curve) that define
                    boundaries of a NURBS surface.  You include these trimming loops in the

                <para>
                    The definition for a NURBS surface can contain many trimming loops.  For
                    example, if you wrote a definition for a NURBS surface that resembled a
                    rectangle with a hole punched out, the definition would contain two trimming
                    loops.  One loop would define the outer edge of the rectangle; the other
                    would define the hole punched out of the rectangle.  The definitions of each
                    of these trimming loops would be bracketed by a <see cref="M:Tao.OpenGl.Glu.gluBeginTrim(Tao.OpenGl.Glu.GLUnurbs)"/>
                    and <b>gluEndTrim</b> pair.

                <para>
                    The definition of a single closed trimming loop can consist of multiple curve
                    segments, each described as a piecewise linear curve (see
                    <see cref="M:Tao.OpenGl.Glu.gluPwlCurve(Tao.OpenGl.Glu.GLUnurbs,System.Int32,System.Single[],System.Int32,System.Int32)"/>) or as a single NURBS curve (see
                    <see cref="M:Tao.OpenGl.Glu.gluNurbsCurve(Tao.OpenGl.Glu.GLUnurbs,System.Int32,System.Single[],System.Int32,System.Single[],System.Int32,System.Int32)"/>), or as a combination of both in any order.  The
                    only library calls that can appear in a trimming loop definition (between the
                    calls to <see cref="M:Tao.OpenGl.Glu.gluBeginTrim(Tao.OpenGl.Glu.GLUnurbs)"/> and <b>gluEndTrim</b> are
                    <see cref="M:Tao.OpenGl.Glu.gluPwlCurve(Tao.OpenGl.Glu.GLUnurbs,System.Int32,System.Single[],System.Int32,System.Int32)"/> and <see cref="M:Tao.OpenGl.Glu.gluNurbsCurve(Tao.OpenGl.Glu.GLUnurbs,System.Int32,System.Single[],System.Int32,System.Single[],System.Int32,System.Int32)"/>.

                <para>
                    The area of the NURBS surface that is displayed is the region in the domain
                    to the left of the trimming curve as the curve parameter increases.  Thus,
                    the retained region of the NURBS surface is inside a counterclockwise
                    trimming loop and outside a clockwise trimming loop.  For the rectangle
                    mentioned earlier, the trimming loop for the outer edge of the rectangle runs
                    counterclockwise, while the trimming loop for the punched-out hole runs
                    clockwise.
                </para>
                <para>
                    If you use more than one curve to define a single trimming loop, the curve
                    segments must form a closed loop (that is, the endpoint of each curve must be
                    the starting point of the next curve, and the endpoint of the final curve
                    must be the starting point of the first curve).  If the endpoints of the
                    curve are sufficiently close together but not exactly coincident, they will
                    be coerced to match.  If the endpoints are not sufficiently close, an error
                    results (see <see cref="M:Tao.OpenGl.Glu.gluNurbsCallback(Tao.OpenGl.Glu.GLUnurbs,System.Int32,Tao.OpenGl.Glu.NurbsBeginCallback)"/>).
                </para>
                <para>
                    If a trimming loop definition contains multiple curves, the direction of the
                    curves must be consistent (that is, the inside must be to the left of all of
                    the curves).  Nested trimming loops are legal as long as the curve
                    orientations alternate correctly.  If trimming curves are self-intersecting,
                    or intersect one another, an error results.

                    The matrix maps the reference point to the negative z axis and the eye point

                    scene therefore maps to the center of the viewport.  Similarly, the direction
                    described by the UP vector projected onto the viewing plane is mapped to the
                    positive y axis so that it points upward in the viewport.  The UP vector must
                    not be parallel to the line of sight from the eye point to the reference

                                the specific error that occurred.  There are 37 errors unique to
                                NURBS named <see cref="F:Tao.OpenGl.Glu.GLU_NURBS_ERROR1"/> through

                                The normal callback is invoked as the vertex normal is generated.
                                The components of the normal are stored in the parameter
                                <i>normalData</i>.  In the case of a NURBS curve, the callback

                                (<see cref="F:Tao.OpenGl.Gl.GL_MAP1_NORMAL"/>).  In the case of a NURBS

                                map.  If a normal map is not provided then a surface normal is
                                computed in a manner similar to that described for evaluators
                                when <see cref="F:Tao.OpenGl.Gl.GL_AUTO_NORMAL"/> is enabled.  The default

                                The vertex callback indicates a vertex of the primitive.  The
                                coordinates of the vertex are stored in the parameter
                                <i>vertexData</i>.  All the generated vertices have dimension 3,
                                that is, homogeneous coordinates have been transformed into
                                affine coordinates.  The default vertex callback function is
                                <c>null</c>. The delegate prototype for this callback is

                                when <see cref="F:Tao.OpenGl.Gl.GL_AUTO_NORMAL"/> is enabled.  The default

                                The texture callback is invoked as the texture coordinates of a

                                be 1, 2, 3, or 4 depending on which type of texture map is
                                specified (<see cref="F:Tao.OpenGl.Gl.GL_MAP1_TEXTURE_COORD_1"/>,

                                The error function is called when an error is encountered.  Its
                                single argument is of type <see cref="T:System.Int32"/>, and it indicates
                                the specific error that occurred.  There are 37 errors unique to
                                NURBS named <see cref="F:Tao.OpenGl.Glu.GLU_NURBS_ERROR1"/> through

                                The normal callback is invoked as the vertex normal is generated.
                                The components of the normal are stored in the parameter
                                <i>normalData</i>.  In the case of a NURBS curve, the callback
                                function is effective only when the user provides a normal map
                                (<see cref="F:Tao.OpenGl.Gl.GL_MAP1_NORMAL"/>).  In the case of a NURBS
                                surface, if a normal map (<see cref="F:Tao.OpenGl.Gl.GL_MAP2_NORMAL"/>) is
                                provided, then the generated normal is computed from the normal
                                map.  If a normal map is not provided then a surface normal is
                                computed in a manner similar to that described for evaluators
                                when <see cref="F:Tao.OpenGl.Gl.GL_AUTO_NORMAL"/> is enabled.  The default
                                normal callback function is <c>null</c>.  The delegate

                                be 1, 2, 3, or 4 depending on which type of texture map is
                                specified (<see cref="F:Tao.OpenGl.Gl.GL_MAP1_TEXTURE_COORD_1"/>,

                                The error function is called when an error is encountered.  Its

                                the specific error that occurred.  There are 37 errors unique to
                                NURBS named <see cref="F:Tao.OpenGl.Glu.GLU_NURBS_ERROR1"/> through
                                <see cref="F:Tao.OpenGl.Glu.GLU_NURBS_ERROR37"/>.  Character strings describing

                                The normal callback is invoked as the vertex normal is generated.
                                The components of the normal are stored in the parameter
                                <i>normalData</i>.  In the case of a NURBS curve, the callback
                                function is effective only when the user provides a normal map
                                (<see cref="F:Tao.OpenGl.Gl.GL_MAP1_NORMAL"/>).  In the case of a NURBS

                                provided, then the generated normal is computed from the normal
                                map.  If a normal map is not provided then a surface normal is
                                computed in a manner similar to that described for evaluators
                                when <see cref="F:Tao.OpenGl.Gl.GL_AUTO_NORMAL"/> is enabled.  The default
                                normal callback function is <c>null</c>.  The delegate
                                prototype for this callback is

                                parameter <i>texCoord</i>.  The number of texture coordinates can
                                be 1, 2, 3, or 4 depending on which type of texture map is
                                specified (<see cref="F:Tao.OpenGl.Gl.GL_MAP1_TEXTURE_COORD_1"/>,

                                The vertex callback indicates a vertex of the primitive.  The
                                coordinates of the vertex are stored in the parameter
                                <i>vertexData</i>.  All the generated vertices have dimension 3,
                                that is, homogeneous coordinates have been transformed into
                                affine coordinates.  The default vertex callback function is
                                <c>null</c>. The delegate prototype for this callback is
                                <see cref="T:Tao.OpenGl.Glu.NurbsVertexCallback"/>.

                                map.  If a normal map is not provided then a surface normal is
                                computed in a manner similar to that described for evaluators
                                when <see cref="F:Tao.OpenGl.Gl.GL_AUTO_NORMAL"/> is enabled.  The default

                                The texture callback is invoked as the texture coordinates of a
                                vertex are generated.  These coordinates are stored in the
                                parameter <i>texCoord</i>.  The number of texture coordinates can
                                be 1, 2, 3, or 4 depending on which type of texture map is
                                specified (<see cref="F:Tao.OpenGl.Gl.GL_MAP1_TEXTURE_COORD_1"/>,

                                The error function is called when an error is encountered.  Its
                                single argument is of type <see cref="T:System.Int32"/>, and it indicates
                                the specific error that occurred.  There are 37 errors unique to
                                NURBS named <see cref="F:Tao.OpenGl.Glu.GLU_NURBS_ERROR1"/> through

                                The normal callback is invoked as the vertex normal is generated.
                                The components of the normal are stored in the parameter
                                <i>normalData</i>.  In the case of a NURBS curve, the callback
                                function is effective only when the user provides a normal map
                                (<see cref="F:Tao.OpenGl.Gl.GL_MAP1_NORMAL"/>).  In the case of a NURBS

                                provided, then the generated normal is computed from the normal
                                map.  If a normal map is not provided then a surface normal is
                                computed in a manner similar to that described for evaluators
                                when <see cref="F:Tao.OpenGl.Gl.GL_AUTO_NORMAL"/> is enabled.  The default
                                normal callback function is <c>null</c>.  The delegate
                                prototype for this callback is

                                The error function is called when an error is encountered.  Its

                                the specific error that occurred.  There are 37 errors unique to
                                NURBS named <see cref="F:Tao.OpenGl.Glu.GLU_NURBS_ERROR1"/> through
                                <see cref="F:Tao.OpenGl.Glu.GLU_NURBS_ERROR37"/>.  Character strings describing

                                The normal callback is invoked as the vertex normal is generated.
                                The components of the normal are stored in the parameter
                                <i>normalData</i>.  In the case of a NURBS curve, the callback
                                function is effective only when the user provides a normal map
                                (<see cref="F:Tao.OpenGl.Gl.GL_MAP1_NORMAL"/>).  In the case of a NURBS

                                provided, then the generated normal is computed from the normal
                                map.  If a normal map is not provided then a surface normal is
                                computed in a manner similar to that described for evaluators
                                when <see cref="F:Tao.OpenGl.Gl.GL_AUTO_NORMAL"/> is enabled.  The default
                                normal callback function is <c>null</c>.  The delegate
                                prototype for this callback is

                                map.  If a normal map is not provided then a surface normal is
                                computed in a manner similar to that described for evaluators
                                when <see cref="F:Tao.OpenGl.Gl.GL_AUTO_NORMAL"/> is enabled.  The default

                                The texture callback is invoked as the texture coordinates of a
                                vertex are generated.  These coordinates are stored in the
                                parameter <i>texCoord</i>.  The number of texture coordinates can
                                be 1, 2, 3, or 4 depending on which type of texture map is
                                specified (<see cref="F:Tao.OpenGl.Gl.GL_MAP1_TEXTURE_COORD_1"/>,

                                The error function is called when an error is encountered.  Its
                                single argument is of type <see cref="T:System.Int32"/>, and it indicates
                                the specific error that occurred.  There are 37 errors unique to
                                NURBS named <see cref="F:Tao.OpenGl.Glu.GLU_NURBS_ERROR1"/> through

                                The normal callback is invoked as the vertex normal is generated.
                                The components of the normal are stored in the parameter
                                <i>normalData</i>.  In the case of a NURBS curve, the callback
                                function is effective only when the user provides a normal map
                                (<see cref="F:Tao.OpenGl.Gl.GL_MAP1_NORMAL"/>).  In the case of a NURBS

                                map.  If a normal map is not provided then a surface normal is
                                computed in a manner similar to that described for evaluators
                                when <see cref="F:Tao.OpenGl.Gl.GL_AUTO_NORMAL"/> is enabled.  The default

                                the specific error that occurred.  There are 37 errors unique to
                                NURBS named <see cref="F:Tao.OpenGl.Glu.GLU_NURBS_ERROR1"/> through

                                The normal callback is invoked as the vertex normal is generated.
                                The components of the normal are stored in the parameter

                                (<see cref="F:Tao.OpenGl.Gl.GL_MAP1_NORMAL"/>).  In the case of a NURBS

                                provided, then the generated normal is computed from the normal
                                map.  If a normal map is not provided then a surface normal is
                                computed in a manner similar to that described for evaluators
                                when <see cref="F:Tao.OpenGl.Gl.GL_AUTO_NORMAL"/> is enabled.  The default
                                normal callback function is <c>null</c>.  The delegate
                                prototype for this callback is

                                    The combine callback is called to create a new vertex when

                                    features.  The function takes four arguments: an array of

                                    0.  <i>coordinates</i> gives the location of the new vertex.

                                    The edge flag callback is similar to
                                    <see cref="M:Tao.OpenGl.Gl.glEdgeFlag(System.Int32)"/>.  The function takes a single
                                    boolean flag that indicates which edges lie on the polygon
                                    boundary.  If the flag is <see cref="F:Tao.OpenGl.Gl.GL_TRUE"/>, then
                                    each vertex that follows begins an edge that lies on the
                                    polygon boundary, that is, an edge that separates an interior
                                    region from an exterior one.  If the flag is
                                    <see cref="F:Tao.OpenGl.Gl.GL_FALSE"/>, then each vertex that follows
                                    begins an edge that lies in the polygon interior.  The edge
                                    flag callback (if defined) is invoked before the first
                                    vertex callback.

                                    Since triangle fans and triangle strips do not support edge
                                    flags, the begin callback is not called with

                                    callback is provided.  (If the callback is initialized to
                                    <c>null</c>, there is no impact on performance).  Instead,
                                    the fans and strips are converted to independent triangles.

                                The vertex callback is invoked between the begin and end
                                callbacks.  It is similar to Gl.glVertex*, and it defines the
                                vertices of the triangles created by the tessellation process.
                                The function takes a pointer as its only argument.  This pointer
                                is identical to the opaque pointer provided by the user when the
                                vertex was described (see <see cref="M:Tao.OpenGl.Glu.gluTessVertex(Tao.OpenGl.Glu.GLUtesselator,System.Double[],System.Byte[])"/>).  The

                                    The edge flag callback is similar to
                                    <see cref="M:Tao.OpenGl.Gl.glEdgeFlag(System.Int32)"/>.  The function takes a single
                                    boolean flag that indicates which edges lie on the polygon
                                    boundary.  If the flag is <see cref="F:Tao.OpenGl.Gl.GL_TRUE"/>, then
                                    each vertex that follows begins an edge that lies on the
                                    polygon boundary, that is, an edge that separates an interior
                                    region from an exterior one.  If the flag is
                                    <see cref="F:Tao.OpenGl.Gl.GL_FALSE"/>, then each vertex that follows
                                    begins an edge that lies in the polygon interior.  The edge
                                    flag callback (if defined) is invoked before the first
                                    vertex callback.

                                    Since triangle fans and triangle strips do not support edge
                                    flags, the begin callback is not called with
                                    <see cref="F:Tao.OpenGl.Gl.GL_TRIANGLE_FAN"/> or

                                    callback is provided.  (If the callback is initialized to
                                    <c>null</c>, there is no impact on performance).  Instead,
                                    the fans and strips are converted to independent triangles.

                    without.  If both versions of a particular callback are specified, then the
                    callback with user-specified polygon data will be used.  Note that the
                    <i>polygonData</i> parameter used by some of the functions is a copy of the
                    pointer that was specified when <see cref="M:Tao.OpenGl.Glu.gluTessBeginPolygon(Tao.OpenGl.Glu.GLUtesselator,System.Byte[])"/> was

                                    The combine callback is called to create a new vertex when

                                    The edge flag callback is similar to
                                    <see cref="M:Tao.OpenGl.Gl.glEdgeFlag(System.Int32)"/>.  The function takes a single
                                    boolean flag that indicates which edges lie on the polygon
                                    boundary.  If the flag is <see cref="F:Tao.OpenGl.Gl.GL_TRUE"/>, then
                                    each vertex that follows begins an edge that lies on the
                                    polygon boundary, that is, an edge that separates an interior
                                    region from an exterior one.  If the flag is
                                    <see cref="F:Tao.OpenGl.Gl.GL_FALSE"/>, then each vertex that follows
                                    begins an edge that lies in the polygon interior.  The edge
                                    flag callback (if defined) is invoked before the first
                                    vertex callback.

                                    Since triangle fans and triangle strips do not support edge

                                    callback is provided.  (If the callback is initialized to
                                    <c>null</c>, there is no impact on performance).  Instead,
                                    the fans and strips are converted to independent triangles.

                                The vertex callback is invoked between the begin and end
                                callbacks.  It is similar to Gl.glVertex*, and it defines the
                                vertices of the triangles created by the tessellation process.
                                The function takes a pointer as its only argument.  This pointer
                                is identical to the opaque pointer provided by the user when the

                                    The edge flag callback is similar to
                                    <see cref="M:Tao.OpenGl.Gl.glEdgeFlag(System.Int32)"/>.  The function takes a single
                                    boolean flag that indicates which edges lie on the polygon
                                    boundary.  If the flag is <see cref="F:Tao.OpenGl.Gl.GL_TRUE"/>, then
                                    each vertex that follows begins an edge that lies on the
                                    polygon boundary, that is, an edge that separates an interior
                                    region from an exterior one.  If the flag is

                                    begins an edge that lies in the polygon interior.  The edge
                                    flag callback (if defined) is invoked before the first
                                    vertex callback.

                                    Since triangle fans and triangle strips do not support edge

                                    callback is provided.  (If the callback is initialized to
                                    <c>null</c>, there is no impact on performance).  Instead,
                                    the fans and strips are converted to independent triangles.

                                    The edge flag callback is similar to
                                    <see cref="M:Tao.OpenGl.Gl.glEdgeFlag(System.Int32)"/>.  The function takes a single
                                    boolean flag that indicates which edges lie on the polygon
                                    boundary.  If the flag is <see cref="F:Tao.OpenGl.Gl.GL_TRUE"/>, then
                                    each vertex that follows begins an edge that lies on the
                                    polygon boundary, that is, an edge that separates an interior
                                    region from an exterior one.  If the flag is
                                    <see cref="F:Tao.OpenGl.Gl.GL_FALSE"/>, then each vertex that follows
                                    begins an edge that lies in the polygon interior.  The edge
                                    flag callback (if defined) is invoked before the first
                                    vertex callback.

                                    Since triangle fans and triangle strips do not support edge
                                    flags, the begin callback is not called with
                                    <see cref="F:Tao.OpenGl.Gl.GL_TRIANGLE_FAN"/> or
                                    <see cref="F:Tao.OpenGl.Gl.GL_TRIANGLE_STRIP"/> if a non-NULL edge flag
                                    callback is provided.  (If the callback is initialized to
                                    <c>null</c>, there is no impact on performance).  Instead,
                                    the fans and strips are converted to independent triangles.
                                    The delegate prototype for this callback is

                                    The combine callback is called to create a new vertex when
                                    the tessellation detects an intersection, or wishes to merge
                                    features.  The function takes four arguments: an array of

                                    The edge flag callback is similar to
                                    <see cref="M:Tao.OpenGl.Gl.glEdgeFlag(System.Int32)"/>.  The function takes a single
                                    boolean flag that indicates which edges lie on the polygon
                                    boundary.  If the flag is <see cref="F:Tao.OpenGl.Gl.GL_TRUE"/>, then
                                    each vertex that follows begins an edge that lies on the
                                    polygon boundary, that is, an edge that separates an interior
                                    region from an exterior one.  If the flag is

                                    begins an edge that lies in the polygon interior.  The edge
                                    flag callback (if defined) is invoked before the first
                                    vertex callback.

                                    Since triangle fans and triangle strips do not support edge

                                    callback is provided.  (If the callback is initialized to
                                    <c>null</c>, there is no impact on performance).  Instead,
                                    the fans and strips are converted to independent triangles.

                                The vertex callback is invoked between the begin and end
                                callbacks.  It is similar to Gl.glVertex*, and it defines the
                                vertices of the triangles created by the tessellation process.
                                The function takes a pointer as its only argument.  This pointer
                                is identical to the opaque pointer provided by the user when the

                                    The edge flag callback is similar to
                                    <see cref="M:Tao.OpenGl.Gl.glEdgeFlag(System.Int32)"/>.  The function takes a single
                                    boolean flag that indicates which edges lie on the polygon
                                    boundary.  If the flag is <see cref="F:Tao.OpenGl.Gl.GL_TRUE"/>, then
                                    each vertex that follows begins an edge that lies on the
                                    polygon boundary, that is, an edge that separates an interior
                                    region from an exterior one.  If the flag is
                                    <see cref="F:Tao.OpenGl.Gl.GL_FALSE"/>, then each vertex that follows
                                    begins an edge that lies in the polygon interior.  The edge
                                    flag callback (if defined) is invoked before the first
                                    vertex callback.

                                    Since triangle fans and triangle strips do not support edge
                                    flags, the begin callback is not called with

                                    callback is provided.  (If the callback is initialized to
                                    <c>null</c>, there is no impact on performance).  Instead,
                                    the fans and strips are converted to independent triangles.

                                The vertex callback is invoked between the begin and end
                                callbacks.  It is similar to Gl.glVertex*, and it defines the
                                vertices of the triangles created by the tessellation process.
                                The function takes a pointer as its only argument.  This pointer
                                is identical to the opaque pointer provided by the user when the
                                vertex was described (see <see cref="M:Tao.OpenGl.Glu.gluTessVertex(Tao.OpenGl.Glu.GLUtesselator,System.Double[],System.Byte[])"/>).  The
                                delegate prototype for this callback is

                                    The edge flag callback is similar to
                                    <see cref="M:Tao.OpenGl.Gl.glEdgeFlag(System.Int32)"/>.  The function takes a single
                                    boolean flag that indicates which edges lie on the polygon
                                    boundary.  If the flag is <see cref="F:Tao.OpenGl.Gl.GL_TRUE"/>, then
                                    each vertex that follows begins an edge that lies on the
                                    polygon boundary, that is, an edge that separates an interior
                                    region from an exterior one.  If the flag is
                                    <see cref="F:Tao.OpenGl.Gl.GL_FALSE"/>, then each vertex that follows
                                    begins an edge that lies in the polygon interior.  The edge
                                    flag callback (if defined) is invoked before the first
                                    vertex callback.

                                    Since triangle fans and triangle strips do not support edge
                                    flags, the begin callback is not called with
                                    <see cref="F:Tao.OpenGl.Gl.GL_TRIANGLE_FAN"/> or

                                    callback is provided.  (If the callback is initialized to
                                    <c>null</c>, there is no impact on performance).  Instead,
                                    the fans and strips are converted to independent triangles.

                                    The combine callback is called to create a new vertex when
                                    the tessellation detects an intersection, or wishes to merge
                                    features.  The function takes four arguments: an array of

                                    The edge flag callback is similar to
                                    <see cref="M:Tao.OpenGl.Gl.glEdgeFlag(System.Int32)"/>.  The function takes a single
                                    boolean flag that indicates which edges lie on the polygon
                                    boundary.  If the flag is <see cref="F:Tao.OpenGl.Gl.GL_TRUE"/>, then
                                    each vertex that follows begins an edge that lies on the
                                    polygon boundary, that is, an edge that separates an interior
                                    region from an exterior one.  If the flag is

                                    begins an edge that lies in the polygon interior.  The edge
                                    flag callback (if defined) is invoked before the first
                                    vertex callback.

                                    Since triangle fans and triangle strips do not support edge

                                    callback is provided.  (If the callback is initialized to
                                    <c>null</c>, there is no impact on performance).  Instead,
                                    the fans and strips are converted to independent triangles.

                                callbacks.  It is similar to Gl.glVertex*, and it defines the

                                The function takes a pointer as its only argument.  This pointer

                                    The combine callback is called to create a new vertex when
                                    the tessellation detects an intersection, or wishes to merge
                                    features.  The function takes four arguments: an array of

                                    <i>weight</i>; these weights always add up to 1.  All

                                    0.  <i>coordinates</i> gives the location of the new vertex.

                                    The edge flag callback is similar to
                                    <see cref="M:Tao.OpenGl.Gl.glEdgeFlag(System.Int32)"/>.  The function takes a single
                                    boolean flag that indicates which edges lie on the polygon
                                    boundary.  If the flag is <see cref="F:Tao.OpenGl.Gl.GL_TRUE"/>, then
                                    each vertex that follows begins an edge that lies on the
                                    polygon boundary, that is, an edge that separates an interior
                                    region from an exterior one.  If the flag is
                                    <see cref="F:Tao.OpenGl.Gl.GL_FALSE"/>, then each vertex that follows
                                    begins an edge that lies in the polygon interior.  The edge
                                    flag callback (if defined) is invoked before the first
                                    vertex callback.

                                    Since triangle fans and triangle strips do not support edge
                                    flags, the begin callback is not called with
                                    <see cref="F:Tao.OpenGl.Gl.GL_TRIANGLE_FAN"/> or

                                    callback is provided.  (If the callback is initialized to
                                    <c>null</c>, there is no impact on performance).  Instead,
                                    the fans and strips are converted to independent triangles.

                                The vertex callback is invoked between the begin and end
                                callbacks.  It is similar to Gl.glVertex*, and it defines the
                                vertices of the triangles created by the tessellation process.
                                The function takes a pointer as its only argument.  This pointer
                                is identical to the opaque pointer provided by the user when the

                                    The edge flag callback is similar to
                                    <see cref="M:Tao.OpenGl.Gl.glEdgeFlag(System.Int32)"/>.  The function takes a single
                                    boolean flag that indicates which edges lie on the polygon
                                    boundary.  If the flag is <see cref="F:Tao.OpenGl.Gl.GL_TRUE"/>, then
                                    each vertex that follows begins an edge that lies on the
                                    polygon boundary, that is, an edge that separates an interior
                                    region from an exterior one.  If the flag is
                                    <see cref="F:Tao.OpenGl.Gl.GL_FALSE"/>, then each vertex that follows
                                    begins an edge that lies in the polygon interior.  The edge
                                    flag callback (if defined) is invoked before the first
                                    vertex callback.

                                    Since triangle fans and triangle strips do not support edge
                                    flags, the begin callback is not called with
                                    <see cref="F:Tao.OpenGl.Gl.GL_TRIANGLE_FAN"/> or

                                    callback is provided.  (If the callback is initialized to
                                    <c>null</c>, there is no impact on performance).  Instead,
                                    the fans and strips are converted to independent triangles.

                    These callbacks are used by the tessellation object to describe how a polygon
                    specified by the user is broken into triangles.  Note that there are two
                    versions of each callback: one with user-specified polygon data and one
                    without.  If both versions of a particular callback are specified, then the
                    callback with user-specified polygon data will be used.  Note that the
                    <i>polygonData</i> parameter used by some of the functions is a copy of the
                    pointer that was specified when <see cref="M:Tao.OpenGl.Glu.gluTessBeginPolygon(Tao.OpenGl.Glu.GLUtesselator,System.Byte[])"/> was

                                    Since triangle fans and triangle strips do not support edge
                                    flags, the begin callback is not called with

                                    callback is provided.  (If the callback is initialized to

                                    the fans and strips are converted to independent triangles.

                                indicate the start of a (triangle) primitive.  The function takes
                                a single argument of type <see cref="T:System.Int32"/>.  If the
                                <see cref="F:Tao.OpenGl.Glu.GLU_TESS_BOUNDARY_ONLY"/> property is set to
                                <see cref="F:Tao.OpenGl.Gl.GL_FALSE"/>, then the argument is set to either
                                <see cref="F:Tao.OpenGl.Gl.GL_TRIANGLE_FAN"/>,
                                <see cref="F:Tao.OpenGl.Gl.GL_TRIANGLE_STRIP"/>, or
                                <see cref="F:Tao.OpenGl.Gl.GL_TRIANGLES"/>.  If the

                                <see cref="F:Tao.OpenGl.Gl.GL_TRUE"/>, then the argument will be set to
                                <see cref="F:Tao.OpenGl.Gl.GL_LINE_LOOP"/>.  The delegate prototype for this
                                callback is <see cref="T:Tao.OpenGl.Glu.TessBeginCallback"/>.

                                    The combine callback is called to create a new vertex when
                                    the tessellation detects an intersection, or wishes to merge
                                    features.  The function takes four arguments: an array of

                                    The edge flag callback is similar to
                                    <see cref="M:Tao.OpenGl.Gl.glEdgeFlag(System.Int32)"/>.  The function takes a single
                                    boolean flag that indicates which edges lie on the polygon
                                    boundary.  If the flag is <see cref="F:Tao.OpenGl.Gl.GL_TRUE"/>, then
                                    each vertex that follows begins an edge that lies on the
                                    polygon boundary, that is, an edge that separates an interior
                                    region from an exterior one.  If the flag is
                                    <see cref="F:Tao.OpenGl.Gl.GL_FALSE"/>, then each vertex that follows
                                    begins an edge that lies in the polygon interior.  The edge
                                    flag callback (if defined) is invoked before the first
                                    vertex callback.

                                    Since triangle fans and triangle strips do not support edge
                                    flags, the begin callback is not called with
                                    <see cref="F:Tao.OpenGl.Gl.GL_TRIANGLE_FAN"/> or

                                    callback is provided.  (If the callback is initialized to
                                    <c>null</c>, there is no impact on performance).  Instead,
                                    the fans and strips are converted to independent triangles.

                                The vertex callback is invoked between the begin and end
                                callbacks.  It is similar to Gl.glVertex*, and it defines the
                                vertices of the triangles created by the tessellation process.
                                The function takes a pointer as its only argument.  This pointer
                                is identical to the opaque pointer provided by the user when the
                                vertex was described (see <see cref="M:Tao.OpenGl.Glu.gluTessVertex(Tao.OpenGl.Glu.GLUtesselator,System.Double[],System.Byte[])"/>).  The

                    <b>gluTessNormal</b> describes a normal for a polygon that the program is

                    of the three coordinate axes before tessellation and all output triangles
                    will be oriented CCW with respect to the normal (CW orientation can be
                    obtained by reversing the sign of the supplied normal).  For example, if you
                    know that all polygons lie in the x-y plane, call
                    <c>Glu.gluTessNormal(tess, 0.0, 0.0, 1.0)</c> before rendering any polygons.

                    If the supplied normal is (0.0, 0.0, 0.0) (the initial value), the normal is
                    determined as follows.  The direction of the normal, up to its sign, is found
                    by fitting a plane to the vertices, without regard to how the vertices are
                    connected.  It is expected that the input data lies approximately in the
                    plane; otherwise, projection perpendicular to one of the three coordinate
                    axes may substantially change the geometry.  The sign of the normal is chosen
                    so that the sum of the signed areas of all input contours is nonnegative
                    (where a CCW contour has positive area).

                                    To understand how the winding rule works, consider that the
                                    input contours partition the plane into regions.  The winding
                                    rule determines which of these regions are inside the
                                    polygon.

                                    For a single contour C, the winding number of a point x is
                                    simply the signed number of revolutions we make around x as
                                    we travel once around C (where CCW is positive).  When there
                                    are several contours, the individual winding numbers are
                                    summed.  This procedure associates a signed integer value
                                    with each point x in the plane.  Note that the winding number
                                    is the same for all points in a single region.

                                    The winding rule classifies a region as "inside" if its
                                    winding number belongs to the chosen category (odd, nonzero,
                                    positive, negative, or absolute value of at least two).  The
                                    previous GLU tessellator (prior to GLU 1.2) used the "odd"
                                    rule.  The "nonzero" rule is another common way to define the
                                    interior.  The other three rules are useful for polygon CSG
                                    operations.

                                    to each other might be replaced by a single vertex.  The
                                    tolerance is multiplied by the largest coordinate magnitude
                                    of any input vertex; this specifies the maximum distance that

                                    operation.  If a single feature takes part in several merge
                                    operations, the total distance moved could be larger.

                                    and not in others, or to never merge features at all.  The
                                    initial tolerance is 0.
