    Remove gdk_window_flush_if_exposing as its not needed anymore
    
    We no longer support modifying GdkWindow hierarchies during
    expose events. This is not working anymore anyway as the
    flush operation now does not push already rendered pixels
    in the flushed window from the double buffer to the window.
