    Ensure that all struts we set extends to their boundary
    
    Mutter really expects this, as this is how app-specified struts
    happen. For instance, if the primary display is beside a taller
    screen and is not positioned at the top, then we extend the struts
    for the panel with the size of the unused area above the primary
    monitor.
