Great, Mike. I'm glad to hear that.

Ah, if you are filling the entire destination surface, then yes,
cairo_paint is equivalent, and works just fine. (You don't even need
rectangle;fill to be safe.) It's when you are drawing an image to only a
portion of the destination surface that you'll find that cairo_paint
won't work.

Well, it sounds to me like the bug is in the NoAccel case. I might give
the cairo test suite a run through that and ensure that nothing too
surprising shows up. (The test suite really should hit this case fine.)

Again, thanks for sharing your report. I hope you have lots of fun with
cairo.
