[Mesa-dev] [PATCH 4/5] radv: Fix fragment resolve destination offset.

[Bas Nieuwenhuizen]

The position start at (dst.x, dst.y), so if we want the source to
start at (src.x, src.y), we have to offset by (src.x-dst.x,src.y-dst.y).

Haven't tested that this fixed anything yet, but found by inspection.
