    gdkwindow: ignore shape on client-side windows when recomputing visible regions
    
    Rendering doesn't do much about clipping drawing operations to the window shape,
    although invalidation applies the shape to every window, leaving possibly trails
    of "overrendered" content. So ensure the shape portions get invalidated too when
    the window is moved/resized.
