Subject: [PATCH 03/11] glx: Extend __GLXscreen::createContext to take attributes
The attributes will be used for glXCreateContextAttribsARB additions
in follow-on patches.
v2: Add missing 'int *error' parameters noticed by Christopher James
Halse Rogers.
v3: Remove redundant 'int err;' declaration noticed by Christopher
James Halse Rogers. This was supposed to be in v2, but I missed it.
