I don't think so -- the sun casts sharp shadows.  Ah! at least that's what
it looks like in Dallas, with a clear sky and no clouds at all.  On an
overcast day, you get even illumination from the sky.

As for using radiosity, I'll have to play with the numbers to see if I can
get it to "work".  I suppose varying the distance_maximum is enough to get
it working, or will I have to explore more degrees of freedom?  My earlier
try basically didn't work.
