I know how it works, but I had the strange suspicion that for certain
numbers of blur_samples (so-called hex numbers,
http://mathworld.wolfram.com/HexNumber.html) the pattern used is a
regular hexagonal pattern instead. Some code in both consts.inc and
render.cpp verify my suspicion. However, this is only true for the
first three hex numbers (1 excluded :) ) and not for all of them,
which is kinda sad, because I would love to see it at work for, say,
169 samples. Even if it just creates hexagonal artifacts instead of
square ones, it will still be better, esp. considering that in real
life most shutters are hexagonal.
