Re: How about an SDL_RenderFillQuad function?

It would probably be better to have a function for arbitrary geometry
composed of triangles, like this one (SDL_RenderGeometry()):
https://bugzilla.libsdl.org/show_bug.cgi?id=1734

But that feature has been waiting for over three years...  and this related
one is 5 years old:
https://bugzilla.libsdl.org/show_bug.cgi?id=1138

Either of those would enable us to implement rotated quad rendering and
keep the API lean.

In the meantime, I've suggested SDL_gpu if you really need this now.
