You will see how the media is different brightness, same scene file, and long
box going into media cloud is different too.

POV-Ray 3.7.0's media computations were inconsistent between different
sampling methods, and even between different sampling parameters.

Media computations were changed in the POV-Ray 3.7.1 betas to be more
stable in that respect.

Thanks for doing that. I had planned to try the experiment in 3.7, but hadn't
gotten around to it yet.
