    clutter: Use notify::allocation instead of allocation-changed
    
    We're going to remove the "allocation-changed" signal from ClutterActor
    since it's no longer needed now that ClutterAllocationFlags are gone.
    
    So listen to "notify-allocation" instead, which has been the recommended
    thing to do for some time now anyway.
