xenocara/dist/Mesa/include/GL/internal/dri_interface.h
oga ed108ba924 Two patches cherry picked from mesa master just after 7.8 was branched
(but never made it into the 7.8 branch).

first:
Author: Jesse Barnes <jbarnes@virtuousgeek.org>
Date:   Thu Apr 22 12:47:41 2010 -0700

    DRI2: add config query extension

    Add a new DRI2 configuration query extension.  Allows for DRI2
    client code to query for common DRI2 configuration options.

second:
Author: Jesse Barnes <jbarnes@virtuousgeek.org>
Date:   Thu Apr 22 12:49:03 2010 -0700

    DRI2/GLX: check for vblank_mode in DRI2 GLX code

    Re-add support for the vblank_mode environment and configuration
    variable.  Useful for benchmarking and app control.

The final affect being that config and environment variables for
controlling swap mode work with dri2 now. which helps me a lot with
debugging.
