Load an animation from an SDL_RWops.
int freesrc);IMG_Animation * IMG_LoadAnimation_RW(SDL_RWops *src,
|src||an SDL_RWops that data will be read from.|
|freesrc||non-zero to close/free the SDL_RWops before returning, zero to leave it open.|
Returns a new IMG_Animation, or NULL on error.
freesrc is non-zero, 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 2.6.0.
