    popupMenu: Flip the popup menu triangle for RTL
    
    Triangles should be flipped in RTL. This is the easiest way to do it that
    doesn't rely on modifying the rotating logic, though it is a bit hacky since
    the ClutterActor "scale-x" property technically considers the lower bound
    to be 0. It works, though.
