    clutter/stage: Emit after-paint after painting
    
    ClutterStage:after-paint is supposed to be emitted after all
    painting is done, but before the frame is finished. However,
    as it is right now, it is being emitted after each view is
    painted -- on multi-monitor setups, after-frame is being
    emitted multiple times.
    
    Send after-paint only once, after all views are painted and
    before finishing the frame.
