GL GPUPE

Currently: just a playground for opengl + sdl in rust

Planned: This is a proof of concept for a pixel engine I have been drafting. The plan is to use gfx-hal + a window framework (winit?) to build the actual engine, I wanted to have a simpler environment to build a prototype in to get some experience first. If the mistakes are held to a minimum I will attempt to build the high-level systems in a way so that I can simply swap out rendering and window context systems.

The draft can be found here TODO.

Contribution

The actual implementation will accept contribution. However, this prototype will not as it serves as a learning experience for me
