My previous work to provide muti-texturing support has been extended into a CoglMaterial abstraction that adds control over the texture combine functions (controlling how multiple texture layers are blended together), the gl blend function (used for blending the final primitive with the framebuffer), the alpha function (used to discard fragments based on their alpha channel), describing attributes such as a diffuse, ambient and specular color (for use with the standard OpenGL lighting model), and per layer rotations. (utilizing the new CoglMatrix utility API) For now the only way this abstraction is exposed is via a new cogl_material_rectangle function, that is similar to cogl_texture_rectangle but doesn't take a texture handle (the source material is pulled from the context), and the array of texture coordinates is extended to be able to supply coordinates for each layer. Note: this function doesn't support sliced textures; supporting sliced textures is a non trivial problem, considering the ability to rotate layers. Note: cogl_material_rectangle, has quite a few workarounds, for a number of other limitations within Cogl a.t.m. Note: The GLES1/2 multi-texturing support has yet to be updated to use the material abstraction.
