But the fact that the warning message happens even when a max_gradient is
given by the user is still a bug, isn't it ? Or am I confused about the
purpose of the warning ? Like JRG I was a bit surprised to see my current
scene output hundreds of (useless in this case) iso warnings...

Well, thanks a lot, warning level 0 works.
I'm still wondering at the difference between -GW (turn console display of
warning text off), and WL0 (turns off all warnings), though... -GW should
work, at least, since it's working for #warning, or am I (again) totally
confused by what the text streams mean ? It's true that I never spent much
time investigating this part of Povray as it seemed quite straightforward.
