The code is not generating images remotely right. Just compare to 3.6 
output. Quality is much worse in 3.7 because something is missing. I never 
had the time to track it down though. It is a fairly simple problem for 
certain, but radiosity tests do take a real lot of time.

All this has nothing to do with multithreading or the use of C++ because the 
code was never changed for it. In fact, very little was changed in the 
radiosity code at all (and the lighting code has only been changed a bit). 
In short, a simple problem exists, it is just very time consuming to debug.
