actor: Ignore redraws queued on unmapped actors
actor: Ignore redraws queued on unmapped actors

If an actor is unmapped then it won't be painted, so we can safely
short-circuit out of _clutter_actor_queue_redraw_full() if the mapped
flag is not set.

We need, on the other hand, make an exception for Clones, otherwise
they won't receive notification that the source actor has changed
and they won't be painted.

This allows us to ignore redraws queued on children of invisible
parents, and avoid traversing the scene graph.
