Request for OpenGL 2.1 support
Very interesting project, sadly I cannot make use of it because my hardware only supports OpenGL 2.1 not 3.3, and it's not something that my current situation really allows me to change anytime soon. 

I don't really know how hard of an issue this would be to solve. I understand if it is unfeasible, I just figured I'd at least let you know that there are people that would appreciate wider OpenGL support.
