Translate glsl

[LegNeato]

Hello! Love the project.

I want to translate GLSL to rust. I actually have a translator that's pretty close to done using naga. But I realize c2rust might be a good / different option as well.

1. If you know about GLSL, do you anticipate any major problems?
2. Would you take patches to add support for GLSL? While I don't really do graphics programming, it's my understanding that the semantics at syntax are essentially C with some graphics card specific stuff on top.
