* clutter/clutter-actor.h:
* clutter/clutter-actor.c:
Add new API clutter_actor_move_by(), clutter_actor_get_size()
* clutter/clutter-alpha.c:
* clutter/clutter-alpha.h:
Add clutter alpha sine func
* clutter/clutter-behaviours.h:
* clutter/clutter-behaviours.c:
Add a basic scale behaviour (needs work)
* examples/behave.c: (main):
More playing with new behaviour functionality
* clutter/clutter-feature.c:
* clutter/clutter-feature.h:
