'''OpenGL extension NV.texture_compression_vtc
Overview (from the spec)
This extension adds support for the VTC 3D texture compression
formats, which are analogous to the S3TC texture compression formats,
with the addition of some retiling in the Z direction. VTC has the
same compression ratio as S3TC and uses 4x4x1, 4x4x2, or 4x4x4
blocks.
The official definition of this extension is available here:
http://oss.sgi.com/projects/ogl-sample/registry/NV/texture_compression_vtc.txt
