[cogl-material] Converts clutter-texture/clutter-clone-texture to the material API
This converts clutter-texture to use the new CoglMaterial API instead of cogl_texture_rectangle. This change does not add multi-texturing support to Clutter, it's more about aiming to deprecate cogl_texture_rectangle, and moving everything over to the cogl_set_source(material); cogl_draw_somthing(); coding pattern. With this patch, the code can be built with/without CoglMaterial support so we can do comparisons of the old/new code for a transient period. (look for the USE_COGL_MATERIAL define) Note: The FBO paths haven't currently been tested, so they may need some tweaks.
