OpenGL / WebGPU support

[TolinSimpson]

No pure C library exists to support WebGPU, we could switch to Rust and 5-10x the project size or manually create the bindings.

Also OpenGL will likely need custom bindings for full support, should still work on MacOS even if it is officially deprecated.

I've begun a C99 implementation of the WebGL standard in another repo.

Other graphics/windowing layers to consider are:

WebGL bindings are now complete. See Commit 2eb7dca
