I had something bouncing around in the back of my head this morning, and since
this thread concerns the PRNG, I'll drop this here.

If you look at my issue here:
https://news.povray.org/web.650c19af5bb87ec31f9dae3025979125%40news.povray.org

this exposed what I believe to be a long-standing non-uniformity in the returned
values from POV-Ray's built-in PRNG.

Have we taken a deep look at the values that the PRNG returns?

I was examining this from a color_map point of view way back, and I think it
would be good to have something uniform/linear unless otherwise specified.
