Some driver/card combinations (r200/RV280, i915/915G) don't support OpenGL 2.1.
These create in some corner cases an indirect context instead of a direct
context when calling glXCreateContextAttribsARB(). This happens because of a
bad default value. To avoid this, choose a more sane default OpenGL 1.0 as
mentioned in the ARB_create_context spec:
The default values for GLX_CONTEXT_MAJOR_VERSION_ARB and
GLX_CONTEXT_MINOR_VERSION_ARB are 1 and 0 respectively. In this
case, implementations will typically return the most recent version
of OpenGL they support which is backwards compatible with OpenGL 1.0
(e.g. 3.0, 3.1 + GL_ARB_compatibility, or 3.2 compatibility profile)
v2: remove unneeded changes
This fixes: http://bugs.winehq.org/show_bug.cgi?id=34238
NOTE: This is a candidate for the Mesa stable branch.
