        * clutter/clutter-private.h:
        * clutter/clutter-main.c:
        Add a hash to global clutter context mapping all parented actor
        id's to actors.
        Add clutter_get_actor_by_id() call.
        Convert picking machinery to use above.
        (performance/simpler composite actor creation)

        * clutter/clutter-stage.c: (clutter_stage_fullscreen),
        (clutter_stage_unfullscreen), (clutter_stage_event):
        Only set the fullscreen property on stage state fullscreen event(#545)
        Experimental as could be painful to implement on non X backends.
