Compute relative fragment coordinates just once

`yyyy` was computed both in QuadRasterizer and PixelRoutine.

This change also addresses an issue where the fragment coordinates were
adjusted for per-sample shading but interpolation of ClipDistance and
CullDistance were inconsistently using the adjusted x coordinate in
combination with the unadjusted y coordinate through the DclipDistance
and DcullDistance values.
