    viewSelector: Mirror open-app-view edge drag gesture for RTL
    
    It makes sense for the gesture to reflect the position of the
    activities button / dash. In RTL locales, those are located on
    the right rather than the left, so make the gesture apply to
    the opposite edge in that case.
