I have been looking at the WebGPU spec and the wgpu crate for a possible WebGPU implementation which arose from a discussion on the discord server.
Problem is, how would we handle the window on which the user would draw to? Adding a window manager to deno would definitively not be a viable solution. wgpu-rs does actually allow to have a windowless setup, but i think most end users would actually want a way to have some sort of window. A window is also required for usage of swap chains; which, once again, many users would want.
