	* clutter/clutter-actor.c:
	(clutter_actor_set_parent): Document and maintain the invariant
	that after setting a realized parent on an actor, the actor is
	also going to be realized.

	(clutter_actor_unparent): Change the invariant that an unparented
	actor is also unrealized: the paint is fast enough to avoid
	unrealizing, since it also causes more problems that what it's
	worth.

	* tests/test-invariants.c (test_show_on_set_parent): Update the
	invariants test because we changed the invariants.
