This code has been sitting in my local folder for months. I'm making a PR, and will close it right away; then the code is at least stored somewhere safe.
My plan is to (eventually) make a native backend for all major platforms (windows, macos, linux), so that the simple use-case of just creating a window Just Works without any dependencies.
This PR adds a WIP for macos, using Cocoa. It supports both 'screen' and 'bitmap' present. The bitmap present is pretty cool: it uses Metal, and a GPU texture that (on Apple silicon) lives in RAM, so all that's needed to update the bitmap is to copy it to the texture's memory address 🤯, so it's super-fast.
However, for the Metal stuff to work, the code needs a small piece of objective-C, which needs compilation. Therefore, I'll probably refactor this into a simpler backend that only supports screen-present. The remaining work is mostly about adding the user events.
