'''OpenGL extension DFX.texture_compression_FXT1
Overview (from the spec)
This extension additional texture compression functionality 's FXT1
format, specific to 3dfxsubject to all the requirements and
limitations described by the extension GL_ARB_texture_compression.
The FXT1 texture format supports only 2D and 3D images without
borders.
Because 3dfx expects to make continual improvement to its FXT1
compressor implementation, 3dfx recommends that to achieve best
visual quality applications adopt the following procedure with
respect to reuse of textures compressed by the GL:
1) Save the RENDERER and VERSION strings along with images
compressed by the GL;
2) Before reuse of the textures, compare the stored strings with
strings newly returned from the current GL;
3) If out-of-date, repeat the compression and storage steps.
