I tried to reuse samples between intervals (i.e. the last sample of an
interval would be reused as the first sample of the next).  Unfortunately,
the samples already had a weight applied to them that was proportional to
the length of the interval.  Thus, one sample from all intervals except for
the first could have an incorrect weight

The problem would not show up if all the intervals were the same length (all
the same weight).  However, if one interval was shorter (because it
represented a lit interval that was part of a spotlight), then the weights
would be thrown off and things would look bad.  More samples meant that the
error in that one sample would not show up as much.

The solution is to not reuse the samples.  this means a bit slower
rendering, but it at least produces correct results.  I tried to reuse the
samples and compensate for the incorrect weights, but it didn't work.
