I don't think these are structures deep in the geometry library. It can
be the structures of the users, something in a picture or database.
Which is "adapted" to the Boost.Geometry Point Concept (this is normally
done by one Macro call).

The spatial index could then use the Point Concept of Boost.Geometry,
and both libraries will work together happily.
