It's time. Now that we have clutter_actor_allocate() respecting the easing state of an actor, and that the LayoutManager animation virtual functions have been deprecated, we can put ClutterAlpha on the chopping block, and be done with it, once and for all. So long, ClutterAlpha; and thanks for all the fish.
