sna/trapezoids: Use incremental region clipping for spans
Within a span, we have the advantage of knowing that we only need to
intersect one box with the clip region, and that box has monotonically
increasing y. This avoid having to compute RegionIntersect for every
span element which was very slow (e.g. libreoffice).
