[Xcb] xcb trouble

[David Reveman]

Hi Jamey!

I've written a new test application for glitz called 'rendertest'. To be
able to compare the output of glitz to X Render, rendertest includes a
simple backend system where graphics systems with X Render semantics can
plug in. I've added an XCB backend, but images are not transfered to
pixmaps correctly. Some images are transfered correctly and some are
not. I'm probably doing something stupid. If you could have a quick look
at it, that would be great. rendertest can be found in cairo CVS.

btw, would it be possible to use XCB for finding visuals, creating
windows... and then just use ordinary glx calls for the GLX protocol?
