Yeah I've seen those, but 2.1 comp or 3.2 core is what you can "count on officially" as of now. I'd rather have code branches just depending on GL_VERSION, and none ever depending on extensions... if extensions make it in the next core profile, they can make it into my code. Then, if that version shows up on OSX 5 years later, great for those Macster users, they're into retro stuff anyway ;)
