Add native macOS renderer backend

[Samuel-Martineau]

By curiosity, do you mean implementing a Metal backend, or something that would render to native components?

If you meant Metal, how would this be better than say, SDL with Metal.

If you meant native components, I wonder how feasible this is, considering how "opinionated" macOS UI elements are.

Uhm i dont think metal would be the target for anything 2D and that would require also other basic window management libraries. My proposal here was to have something native that requires no sdl, but as alternative sdl is kind of the generic way to work everywhere

@trufae Anything on macOS would ultimately involve touching Cocoa. I think you are suggesting a CoreGraphics backend. This would be analogous to a GDI or Direct2D backend in Windows land.
