Revive the bbox circle of confusion calculation for PO #299

Now that we're redistributing everything, I can see a lot of bad sampling in areas that are heavily aberrated, but where the thinlens model produces a flat field

mmmm... this has a lot of drawbacks:

takes additional time
sample counts vary much more wildly because it's an average of some sample set (not analytical like coc)
