Interested in helping or co-funding ?

toTopoGeom populates a topology, doesn't strictly need TIN but should
already be playing nicely with either the COLLECTION of LINES output
from Delaunay.

TIN is a pretty new type, not much support for it, yet, but yes, it
would be useful if not else for transporting TINs (input/output formats!)
