Not yet, I think there are too many official issues. Sorry, I don’t know English, this is from Google Translat

@icculus Can this be added to SDL3? The software rendering part, which I can't achieve

Maybe this could be implemented as new function on top of SDL_RenderCopy() So that we don't have do each backend implementation. With batching it's going to be fast ..

Wrap modes are often part of a Texture's state (or sampler state in newer low level graphics APIs) rather than draw parameters. Once the new low level 3d graphics API exists, it will no doubt be able to manage sampler state so it'd probably be trivial to expose to SDL_Render at that point.

However, as long as SDL_Render supports emulation of non-power-of-two textures, wrap modes can't be properly implemented for those textures on systems that do that.
