Hey Ian, we spoke a few months ago when I was working on implementing 
the GLX extension for XCB (xcb.freedesktop.org).  Anyways, I've modified 
glX_proto_send.py to generate the code necessary for it to use the XCB 
library instead of Xlib.  It outputs the new code in between #ifdef 
USE_XCB / #endif.  So it you can compile with either xlib or xlib/xcb.

At the moment it only works with the single ops as we do not have 
support for render ops in xcb yet.  But I think it's a start.

Do the patches look okay?  If so could someone possibly commit it to cvs?

Included:
glX_proto_send.py.diff
Makefile.diff (for Mesa/Makefile)
linux-x86-xcb (place in Mesa/configs, basically just tells CFLAGS to 
define USE_XCB)

Thanks,
Jeremy
