    clutter/stage: Make clutter_stage_schedule_update() public API
    
    It's effectively used by mutter by abusing a ClutterTimeline to scedule
    updates.  Timelines are not really suited in places that is done, as it
    is really just about getting a single new update scheduled whenever
    suitable, so expose the API so we can use it directly.
