/**
 * Native bindings to the EXT_texture_storage_compression extension.
 * 
 * Applications may wish to take advantage of framebuffer compression. Some platforms may support framebuffer compression at fixed bitrates. Such
 * compression algorithms generally produce results that are visually lossless, but the results are typically not bit-exact when compared to a
 * non-compressed result.
 * 
 * This extension enables applications to opt-in to compression for immutable textures.
 * 
 * Requires {@link GLES30 GLES 3.0}.
