I created a 2D rendering engine with / for SDL_2.
It is cross-platform, tested on Debian and Windows.
Quick and easy to use. I developed it with SDL_2, SDL_Image, and SDL_TTF, with a little creativity we can do any kind of rendering with.
I developed it in C and works without modification with C ++.
I will publish it in the next few days if anyone is interested.
