1. Bleeding Edge SDL3?

Hi all,

I have been working a wrapper for SDL3. SDL3 is still in active development and as it has been updating, I have been keeping up with it for the most part. The wrapper wraps SDL3 of course and the new functions and the re-worked API. It is mostly similar to SDL2, with some differences here and there. Keep in mind this would be a bleeding edge version and would be updated a lot and some things may not work or break. If not, I can just wait until a stable release of SDL3 is released. The wrapper of course uses Greg's Euphoria version of the FFI library. This helps greatly with wrapping structs.
