Absolutely right! And this is an inspiring project.

It has been some while since I last used UberPOV, in fact since I 
switched to the successive v3.8 betas, and I guess those would also 
avoid radiosity artefacts, especially when using stochastic render? I am 
mumbling away, really, and it should be tested of course.

Hmm... didn't remember that one.
