Hi all! I've started fooling around with radiosity and... not that i want to
sound rude to our beloved developing team, but i can't seem to get anything
sensible when radiosity is on, even in the simplest situations.

For instance, a red box over a plain plane (which can be thought of as a
beta version of the rsocp) leads to the results posted in pbtb. I don't
know the insides of Povray, but i'd say that currently the radiosity
samples are not distributed randomly in all directions of space, but rather
chosen following a wicked kind of reflection.

The sphere case is yet weirder, a cap of the sphere looks like it's been
bumped in.

I tried to play with:
- count: Seems to do nothing at all.
- error_bound: does have an effect, the lower, the sharper the image.
- recursion_limit: does **strongly** slow down the rendering, much more than
in 3.6.1a.
- pretrace_end: the lower, the smoother the results, as expected.

Well, i'm willing to keep testing and identifying... but maybe i'd need
pointers from experienced beta testers. Thanks!
