AshTouchTransformController calls to UpdateTouchTransforms() at a couple of points that relies on the WindowTreeHostManager. I don't think it makes sense for ash to use display::TouchTransformController at all in mus/mushrome. So, either this code can safely be ignored for mus/mushrome, or we need to make mus do what AshTouchTransformController is doing.
