    win32: Make flush/sync work like in X
    
    gdk_flush() should gdk_display_sync() on all open displays.
    
    Both for display_flush and display_sync it seems useful to call
    GdiFlush, but we don't have anything extra to do for display_sync,
    as there is no inherent roundtrip on win32.
    
    This should close bug #84314
