Reorder the separable blur passes into XXX/YYY, with an image transpose on the last pass of each group.  This results in continuguous memory reads in all passes, giving a 22% speedup on theverge.skp over the previous separable implementation, and a 30%-50% improvement over the existing implementation (depending on platform).
