Okay, so do you think we can take the patch for the GXcopy case, and fall
back to mi otherwise?


And how about https://bugs.freedesktop.org/show_bug.cgi?id=99708 - should
we fall back to mi until we have a better approximation in GLAMOR?

It's sad to see acceleration go, but currently it seems to create a lot of
confusion. And raw X11 ops are barely used (if at all) in average modern
desktop environments.
