OpenGL extension DFX.texture_compression_FXT1
This module customises the behaviour of the OpenGL.raw.GL.DFX.texture_compression_FXT1 to provide a more Python-friendly API
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GL; 2) Before reuse of the textures, compare the stored strings with strings newly returned from the current GL; 3) If out-of-date, repeat the compression and storage steps.
