Detailed Description

A geometry which carries its type at runtime instead of statically.

The counterpart to Geometry: such a geometry models no single shape - it reports which one it holds instead - so it is not usable with the generic algorithms and has to be narrowed to a Geometry first. This is what lets a layer hold whatever its data source happens to contain.
