From: Ian Romanick <[email protected]>
If the driver supports __DRI2_ROBUSTNESS, then enable
GLX_ARB_create_cotnext_robustness as well. If robustness values are
passed to glXCreateContextAttribsARB and the driver doesn't support
__DRI2_ROBUSTNESS, existing drivers will already generate the correct
error values (so that the correct GLX errors are generated).
