Really lazy implementation for now, just draws all sprites every frame. In the future should implement proper compositing with damage tracking. All CG types other than QNT are removed. From what I've seen, System 4 games use QNT, PNG, AJP (encrypted JPEG) and DCF (seems to be a format for partial CG updates). QNT is by far the most common format.
