Load a ICO image directly.
SDL_Surface * IMG_LoadICO_RW(SDL_RWops *src);
|src||an SDL_RWops to load image data from.|
Returns SDL surface, or NULL on error
If you know you definitely have a ICO image, you can call this function, which will skip SDL_image's file format detection routines. Generally it's better to use the abstract interfaces; also, there is only an SDL_RWops interface available here.
This function is available since SDL_image 3.0.0.
