Thanks. There is indeed a cosmetic bug in filter_extensions(), unrelated to the
crash.

About the crash itself, Michael's analysis looks right. The game requests an
OpenGL 3.1 context, which in the case of Mesa is in practice a 3.2 core profile
context. That's perfectly legitimate but unfortunately not expected by the
game, which on Windows would always get an actual 3.1 context with
ARB_compatibility.

The missing legacy entrypoints could be partially emulated in opengl32.dll by
generating and plugging in some ARB -> core wrapper functions. That's quite
ugly and insufficient in general and specifically for RAGE, as Michael
discovered.

I think there isn't much we can reasonably do here. I'd call this a game bug
and it's likely other OpenGL Windows games suffer from the same issue. I'm
resolving this bug as invalid for the time being.
