        event_loop(init &s, std::uint32_t const wid) : sdl{s}, window_id{wid} {}

        event_loop(init &s, W const &w)
        : event_loop{s, SDL_GetWindowID(w.get())} {}

Coroutine tasks to run

These should be run by the application in order for the event loop to be fully and correctly connected to the rest of the application.

Run the event loop until the UX is done
