thread safe SDL_Renderer

[volt-bot]

I still don't understand why we don't have thread safe SDL_renderer. I mean it's almost 2023. what isn't multithread accessible. my team is working on a modern fully featured GUI but are having a hard time implementing some features due to lack of a thread safe renderer. we were even thinking on rewriting the whole code base with a different graphics API. we've testeted the SDL's renderer on multithreaded systems and works fine with vulkan and direct x contexts. why are we letting a single API "OPENGL" prevent us from getting in on the fun and capabilities of the current tech "threading" caps.

We are working on a next-gen 3D API that will be thread safe (and we will write an implementation of the existing 2D API that uses this new thing behind the scenes).

In the meantime, if the existing Direct3D or whatever code is doing what you need, SDL_CreateRenderer can be used to select it specifically, or you can enumerate renderers and choose anything that isn't OpenGL, or just build SDL without OpenGL support so you definitely won't get it by default.

Moving this to SDL3 as a TODO item.

I would be curious to learn more about this next-gen 3D API - so far finding information on SDL3 as a whole has been difficult. To have any more info on the specifics plans for this?

There's still a lot of work going on, so we aren't spending a lot of time publicly talking about new stuff at the moment, outside of GitHub. That will change, though!

Thank you for the update, Ill have a look and await further news !
