%description
    This extension provides additional texture compression functionality
    specific to S3's S3TC format (called DXTC in Microsoft's DirectX API),
    subject to all the requirements and limitations described by the extension
    GL_ARB_texture_compression.

This extension supports DXT1, DXT3, and DXT5 texture compression formats.
    For the DXT1 image format, this specification supports an RGB-only mode
    and a special RGBA mode with single-bit "transparent" alpha.
