    clutter-actor: Store the queue_redraw_entry when queueing a redraw
    
    _clutter_stage_queue_actor_redraw returns a pointer to the
    ClutterStageQueueRedrawEntry struct which it allocates. The actor is
    expected to store a pointer to this so that it doesn't need to search
    the list of queued redraws next time a queue redraw is called. However
    _clutter_actor_queue_redraw_full wasn't storing this pointer which
    meant that it thought every queue redraw was the first queue
    redraw. That meant that queueing a redraw with a clip or an effect
    would override any previous attempts to queue a redraw instead of
    trying to combine them.
    
    I think this happened because the old queue_redraw_with_clip also
    didn't store the pointer and queue_redraw_full was based on that.
