From my poor memory, Last time I used it, I think it worked also with straight
stopping, but this was before the povwin code got clearly split and optional.The
issue I had met with radiosity was that some buckets of the image probably got
different rays averaged together so they created small artifact, but the
continue feature could still be considered usable because post render edit would
easily solve those.
