Added tiled 9-grid texture rendering function

Description

New function SDL_RenderTexture9GridTiled, borders and center is tiled instead of stretched. This is a known alternative method for 9-slicing.

Here is the difference (right is tiled):

This looks good to me. I'll add it for the 3.4 milestone, thanks!

Changes to SDL_dynapi_overrides.h and SDL_dynapi_procs.h must not be
inserted, but appended instead. And SDL_dynapi.sym doesn't include the
new proc: Revert manual changes to src/dynapi/* and run gendynapi.py

Gotcha, amended, clean commit with generated api is ready.

Actually, just revert the dynapi changes entirely. We’ll regenerate them once we merge, to avoid conflicts with other new API functions.

All right, I will keep that in mind for the future

Question: this tiles left-to-right, and is not configurable.
Is that something that people want to configure?
It's e.g. possible to tile from the center, or right-to-lleft.

Never came across such behavior. Even in modern game engines it's not configurable. The most common and default behavior is just this.

Hmm, build failed due to undefined reference to 'SDL_RenderTexture9GridTiled', but that can't be right, it is clearly defined in all the right places, same as SDL_RenderTexture9Grid. Should I worry or is Haiku to blame?

That's expected because you didn't add dynapi. You can ignore it.
All symbols not known by dynapi are considered internal, and not exported from the shared SDL3 library.

Yes, it previously passed CI, you’re good to go. Thank you very much!

I think at that point they can implement it themselves on top of existing primitives. I think we're as robust with 9grid stuff as we want to be after this PR merges.
