TRI creates a constrained triangulation using 'ear-cutting', or 'ear-clipping' of
polygons. The model is a 'relational' form in that the underlying tables are
linked implicitly by unique identifiers.
Ear-cutting is inherently path-based, so this model is only available for
path-based structures, like simple features, PATH(), PATH0() and ARC().
