commit c40e0b51f0d9ef5e1f30f233d7db1e6db9d6681b
Author: Kristian Høgsberg <krh at redhat.com>
Date: Wed Mar 26 19:28:09 2008 -0400
Implement DRI2 direct rendering and update AIGLX to DRI interface changes.
Get rid of glcontextmodes.[ch] from build, rename __GlcontextModes to
__GLXcontext. Drop all #includes of glcontextmodes.h and glcore.h.
Drop the DRI context modes extension.
Add protocol code to DRI2 module and load DRI2 extension by default.
