clutter/actor: Improve clutter_actor_allocate_preferred_size() API
Add a new function to get the fixed size of ClutterActors, clutter_actor_get_fixed_position()
and allow passing the new allocation origin to clutter_actor_allocate_preferred_size()
, which makes it convenient to use from layout managers and allows moving fixed position handling to ClutterFixedLayout.
