OpenGL checking

Needs formatting, currently dumped here to not to lose it.
It seems I found a way to check OpenGL version used by game under Linux, not sure about Mac or Windows, at least it seems to work for me, it's a bit crude, but I'm using the `MESA_GL_VERSION_OVERRIDE` to override version OpenGL version and found the lower ones the game work with: https://www.khronos.org/opengl/wiki/History_of_OpenGL

e.g. I launch the game as `MESA_GL_VERSION_OVERRIDE=3.3 mangohud %command%` with mangohud to verify it has been applied. I test that on Awesomaunts (works with 3.0 but with anything lower just the sound works, screen is black) and Euro Truck Simulator 2 / ATS (refuses to launch with anything lower than 3.3 which makes sense as it's the last OpenGL version supported on Macs). I will update these pages promptly, but it would be nice to have it documented somewhere, maybe I'll leave it on my user page till then, so it doesn't get lost in Discord's discussions
