 * 
 * <p>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).</p>
 * 
 * <p>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}).</p>
 * 
 * <p>The compressed signed luminance-alpha format is reasonably suited for storing compressed normal maps.</p>
 * 
 * <p>Requires {@link GL13 OpenGL 1.3} or {@link ARBTextureCompression ARB_texture_compression}.</p>
