    workspacesView: Only clip non-primary workspace views
    
    The primary workspace is displayed in the overview, and clipping it
    ends up clipping the shadows too. Since Overview's ControlsManager
    itself clips to allocation, no windows in the primary monitor spill
    to other monitors. However, not clipping non-primary monitors might
    end up in situations where their windows spill into the primary one.
    
    Make sure to only clip workspace views of non-primary monitors.
