Tomeu discovered that the unaligned-clip was scaling up by 10% with every call to the drawing function (oops!). So now that that's fixed it was easy to drop in Soeren's fix and get a 1.6x speedup for that test case. So try it out now and let us know if there is still any unexplained slowness. -Carl
