- * In addition to the standard OpenGL lighting model a Cogl material may have
- * one or more layers comprised of textures that can be blended together in
- * order, with a number of different texture combine modes. This function
- * defines a new texture layer.
- *
- * The index values of multiple layers do not have to be consecutive; it is
