The reason I never implemented this back when I adde RPU side data is that
there is a strong chance of generating broken files.

That's because if we do anything to the video with swscale, etc., we're
now encoding RPUs that aren't meant to be applied to that converted video.

For example, this could end up propagating RPUs when the user is tonemapping.
