    reftests: Always wait for rendering to settle
    
    We wait for a few 100ms for rendering to settle in various WMs. So far
    we only did that for windows that were controlled by the WM (aka
    toplevels).
    
    With modern compositing gnome-shell however, this now also applies to
    override-redirect windows, so we now wait there, too.
    
    This makes the reftests a lot slower, but they now actually work when
    running make check in gnome-shell.
