It isn't.

I substantially reworked / fixed fog for povr. Got into it because it 
used the fixed Turbulence() function. Uncovered quite a bit more not 
right once looking at it. There were several reasons the turbulence with 
fog has never worked that well. The turbulence not getting copied when a 
defined fog was copied is one I remember.
