I am trying to create a simple library for c to handle opengl matrix operations.

p.s. I didn't write my own inverse function, I got it from this so question: http://stackoverflow.com/a/1148405

I really hope that I can get some good help with this because matrix math is difficult enough w/o translating it to code. Any functions that I am missing? I would like to avoid adding functions just to have them there unless they'll be useful for rendering pipeline which fits nicely in the 4x4 square matrix.

Also please no comments about rolling up or using loops.
