    clutter/actor: Invalidate last paint volume on absolute geometry changes
    
    The last paint volume is in eye coordinates. When an actor changes
    any transform, all children potentially change their position in
    eye coordinates, and consequently, the last paint volume becomes
    invalid.
    
    Mark the last paint volume as invalid when the absolute geometry
    of an actor changes.
