Ensure the clip rect taken from transformations is cleared when there is no transformation. Normally the failure to clear the clip would not cause a problem, as the final clip would be equal to the window size. However, in the event that the window scale goes on to change (WindowState::m(H/V)Scale that is) the clip will now be specified at the inappropriate scale (notice the way the clip must be divided by H/VScale as SurfaceFlinger will apply the surface transform to the clip).
