Our problem is that given a lat+lon (or X-Y mercator 
projection of it) we need to determine if it is "within" a 
customer-assigned bounary. This is a most commercial use,
so I'll have to check what the GPC library costs. Might
be our best way out, though.

Q: What does the interface for asking the question
   "is this point within the current polygon for a 
   of polygons" look like?

I don't have anything I can contribute (current
code is work for hire, not amenable to CPAN). I've
never actually had any work that requird PDL before.
The most recent release may be amenbable to some 
bioinformatics I'm working on, but that uses Postgres,
which has a working 'within' operator so I'm not yet
sure whether PDL is necessary there (yet).
