In order to unify alpha functions and animation modes in ClutterAlpha we should be able to register alpha functions and get a logical id for them; the logical id will then be available to be used by clutter_alpha_set_mode(). The registration requires API changes in ClutterAlpha constructors and methods. It also provides the chance to shift ClutterAlpha towards the use of animations modes only, and to alpha functions as a convenience API for language bindings alone.
