Historical reasons and method 1. Until pov 3.1 included, the only
available method was method 1. In this case, sampling is completely
random inside each interval, but the intervals take into account the
cones of the available spotlights. This was simply a way to force
more samples to be taken inside spotlights than outside. With
adaptive sampling, there is much less need (especially since the
optimal number of intervals is now computed automatically anyway).
