There is a note about radiosity that say that *exact* reproduction is 
NOT guaranteed from render to render when using radiosity.
It seems to be because radiosity use some montecarlo approximation and 
some other pseudo-random sequences.

There is a flag that can be set to increase the similarity. It will tend 
to slightly increase the rendering time.
