[gnome-control-center/benzea/fix-panel-size-check: 2/2] display: Consider monitors in landscape mode for minimum size

    display: Consider monitors in landscape mode for minimum size
    
    Some devices have panels with a native resolution in portrait mode. In
    these cases the monitor will likely be used in landscape mode.
    
    Accept the modes as if they are landscape rather than portrait. A
    further improvement would be to restrict the orientation setting.
    
    Fixes #639
