code, and even internally Cogl should now be using the material API when
it needs control of these.

* A CoglMesh type and utility API has been added; this is currently used to
support describing texture matrices.
* cogl_alpha_func has been removed, since this is now controlled using the
material API via cogl_material_set_alpha_test_function ()
