glamor: Simplify XV vertex setup.
We were clipping the drawn rectangle to each clip box, then expanding the box to a big triangle to avoid tearing, then drawing each triangle to the destination through a scissor. If we're using a scissor for clipping, though, then we don't need to clip the drawn primitive on the CPU in the first place.
