/**
 * Native bindings to the EXT_texture_compression_latc extension.
 * 
 * This extension introduces four new block-based texture compression formats suited for unsigned and signed luminance and luminance-alpha textures (hence
 * the name "latc" for Luminance-Alpha Texture Compression).
 * 
 * These formats are designed to reduce the storage requirements and memory bandwidth required for luminance and luminance-alpha textures by a factor of
 * 2-to-1 over conventional uncompressed luminance and luminance-alpha textures with 8-bit components ({@link GL11#GL_LUMINANCE8 LUMINANCE8} and {@link GL11#GL_LUMINANCE8_ALPHA8 LUMINANCE8_ALPHA8}).
 * 
 * The compressed signed luminance-alpha format is reasonably suited for storing compressed normal maps.
 * 
 * Requires {@link GL13 OpenGL 1.3} or {@link ARBTextureCompression ARB_texture_compression}.
