I implemented a to_prepared method on Geos::Geometry which produces a
Geos::PreparedGeometry instance that can be used to test
relationships, so it's rather explicit at the moment. I suppose that
functionality could also be hidden away and you'd have to handle
caching and stuff to detect for changes to the underlying geometry and
then update the prepared geometry accordingly and all that jazz. Worth
considering for sure, but at the moment it's just a simple
implementation.
