You're talking about these things in a manner that confuses me. You
talk about GLSL version overrides, and that's what your patch does.
However what you're really trying to do is limit the GL version of the
resulting context. My guess specifically is that you want to turn off
the context version upgrade logic. Either limit ctx->Version or try to
adjust that logic.

I don't see what this has to do with GLSL versions.

Side-note - there's no GLSL version 320. Perhaps you meant 150 (the
GLSL version associated with GL 3.2).
