This is an enhanced version of GLM, which was originally by Nate Robins, with some enhancements by Jeff Rogers (from the GLM_AVL library).
This library loads OBJ files and MTL files, and can display them using OpenGL.
It uses the state-based OpenGL API (up to OpenGL 2.1). If someone wants to contribute OpenGL 3.0 support, please submit a pull request.
