transform cartesian to window coordinates problem

here the clip position's z element should between -w to w,rather than greater than 0.due to this mistakes,some cartesian my be clip to undefined by than comparison.

No file, test, or entry point is named in the report. Start by locating the Cartesian-to-window-coordinate implementation and verify the reported clip-position z behavior against the stated -w to w range. Done means affected Cartesian positions are no longer clipped as undefined by that comparison.
