Returns a list of three nonnegative integers, indicating a version number of SDL_image. For example, the list (2 0 0) indicates SDL_image 2.0.0.
- compiled-version returns the version of SDL_image that the sdl2-image egg was compiled with.
- current-version returns the version of SDL_image that the sdl2-image egg is currently using.
For example, the user may have compiled the sdl2-image egg with SDL_image 2.0.0, then later upgraded SDL_image to 2.1.0, but not yet recompiled the sdl2-image egg with the new version. In such a case, compiled-version would return (2 0 0), and current-version would return (2 1 0). But, features from the new version would not be available until the user recompiles the sdl2-image egg.
