    clutter/stage-cogl: Don't clip when clipped redraws are disabled
    
    It doesn't make sense to set the redraw clip when painting the stage if
    clipped redraws are disabled. That's because when visualizing the redraw
    clip and any new redraws are clipped, the old visualiziations would
    remain visible, leaving multiple confusing rectangles on the screen.
