Fix coordinate error after rotation and scaling in TouchInputMapper
The 'rotateAndScale' will transform raw coordinate into surface
coordinate, but the raw (x, y) values range would be defined in
RawPointerAxes, so we have to transform the raw event using the
RawPointerAxes and the scaling ratio into surface coordinate, then
calculate the offset by the surface frame.
