I think you need to do something like this:
  gfx::Point center = image()->bounds().CenterPoint();
  center.set_x(GetMirroredXInView(center.x()));
and then use |center| in place of |image()->bounds().CenterPoint()|.
Please try it with maximized and not maximized browser window with --lang=he as
well as English layout.
