    Pass through all scroll events to compositor
    
    As with other events, we want to pass through scroll events (button 4/5 presses)
    to the compositor, whether or not they are associated with a particular MetaWindow;
    do this by simply falling through to the normal code path instead of
    separately delivering the events to the compositor.
