- '''OpenGL extension SGIS.texture4D
-
- Overview (from the spec)
-
- This extension defines 4-dimensional texture mapping. If EXT_subtexture
- is supported, this extension also defines a mechanism to redefine a
- portion of an existing 4-dimensional texture image. Because
- EXT_texture3D is required, this extension utilizes the 3-dimensional
- image support defined in by EXT_texture3D as a base for 4-dimensional
- image manipulation.
-
- The 4th dimension has an abstract, rather than physical, reference
- and will be called "extent", since the definition of extent is "that which
- specifies the range or magnitude of an area or volume."
-
- Four-dimensional texture mapping is more constrained than its one, two,
- and three-dimensional counterparts. Mipmapping is not supported, so
- only the level-zero 4-dimensional texture image can be defined. Cubic
- filtering is not supported, so the border width must be either zero or
- one.
-
- Four-dimensional textures are used primarily as color lookup tables for
- color conversion.
-
- The official definition of this extension is available here:
- http://oss.sgi.com/projects/ogl-sample/registry/SGIS/texture4D.txt
