Load an animation from an SDL_RWops.
IMG_Animation * IMG_LoadAnimation_RW(SDL_RWops *src, SDL_bool freesrc);
|an SDL_RWops that data will be read from.
|SDL_TRUE to close/free the SDL_RWops before returning, SDL_FALSE to leave it open.
Returns a new IMG_Animation, or NULL on error.
freesrc is SDL_TRUE, the RWops will be closed before returning, whether this function succeeds or not. SDL_image reads everything it needs from the RWops during this call in any case.
When done with the returned animation, the app should dispose of it with a call to IMG_FreeAnimation().
This function is available since SDL_image 3.0.0.
