I agree. Although I haven't used photons in awhile, I noticed a long time ago
that jitter 0.5 wasn't enough to eliminate visible 'rings', especially seen
close-up. I never mentioned it, though :-(  And I no longer have the test
scene that I used. If 0.5 is still the default, it does need reworking for a
smoother more-random appearance.
