xserver/GL/glx/glxcontext.h
Kristian Høgsberg b9fdfa1534 Implement accelerated indirect rendering by loading DRI drivers directly.
Drop GLcore dependency from glx module.
Work around double destroy case and add DRIUnlockedCallback() function.
New files, lots of code coming from GL/mesa/X/xf86glx.c and the libGL
    loader code.
