Peter Hutterer bafbd99080 dix: work around scaling issues during WarpPointer (#53037) 
In WarpPointer calls, we get input in screen coordinates. They must be
scaled to device coordinates, and then back to screen coordinates for screen
crossing and root coordinates in events.

The rounding errors introduced (and clipping in core/XI 1.x events) can lead
to the actual position being different to the requested input coordinates.
e.g. 200 scales to 199.9999, truncated to 199 in the event.

Avoid this by simply overwriting the scaled screen coordinates with the
input coordinates for the POINTER_SCREEN case.
