dix: Save touchpoint last coordinates before transform. #49347
DDXTouchPointInfoRec.valuators used to store axis values after transform.
This resulted in Coordinate Transformation Matrix
being applied multiple times to the last coordinates,
in the case when only pressure changes in the last touch event.
Changed DDXTouchPointInfoRec.valuators to store values before transform.
