  I would guess that this might add more graininess to the lighting, as the
amount and color of the light will change more randomly from one sampling
point to the next. This might also make it slower as the algorithm can't
reuse old values so often (because now they change more than the error bound
threshold more often).
  (Naturally I can't know for sure as I only have a vague idea about how
Ward's stochastic global illumination algorithm works. This was just a
guess.)
