> RecursivePrefixTreeFilter was modified in ~July 2011 to support spatial filtering of
non-point indexed shapes.  It seems to work when playing with the capability but it isn't
tested.  It really needs to be as this is a major feature.
> I imagine an approach in which some randomly generated rectangles are indexed and then
a randomly generated rectangle is queried.  The right answer can be calculated brute-force
and then compared with the filter.  In order to deal with shape imprecision, the randomly
generated shapes could be generated to fit a course grid (e.g. round everything to a 1 degree
interval).
