Yes, that rendercheck error is known.  I intend to fix it in fb, and have a
patch for it, once I can find some text somewhere confirming that that's how
coordinates work.  I'm pretty sure about it, though.

ajax: you've set the dest texture formats supported to a8r8g8b8.  That's quite
uncommon (only when you're using the argb visual, mostly).  That's probably why
he isn't getting the printfs hit, because you're not seeing any destinations
that can be accelerated to, so the driver's code is never called.

If you're only going to support operations that don't use destination alpha, you
could throw x8r8g8b8 in the mix and get acceleration for the typical 32bpp
framebuffer case.  The best would be if 16bpp could be supported, too.  The use
of piles of magic numbers in this code means someone might have to go look up
how to do that.
