 * Native bindings to the EXT_texture_compression_s3tc extension.

 * 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 {@link ARBTextureCompression 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.
 * 
 * Requires {@link ARBTextureCompression ARB_texture_compression}.
