    display: Run snapping after certain modifications
    
    Anything that affects the size of the screen (or its existance) may
    result in invalid configurations. Do a small effort in trying to fix
    this by calling into the snapping algorithm for the modified monitor.
    
    Addresses issue #247 to a large extend.
