    window-actor/wayland: Update bounds on texture change
    
    This fixes resizing of x windows when running as a wayland compositor by
    ensuring we update the windows bounding region and borders whenever we
    are notified of a new cogl-texture for the internal
    ClutterWaylandSurface actor.
