Pixman only does it because the X server requires regions to be marked as YX-banded to be deigned valid (or 'complete', as an FBO analogy), and a number of the rendering algorithms in the server depend on it. We don't have any of that, so can happily do without banding. A patch to Pixman which would optionally drop the strict banding would be nice, but if there's a small enough region implementation we could use instead, that could work. Cheers, Dan
