[jts-dev] complete overlay with labels

[Michaud Michael <m.michael.michaud@xxxxxxxxx>]

Hi JTS developpers,

I'm searching for the best approach to overlay 2 geometries A and B and label each resulting polygon
with A, B or A+B.
With Polygonizer, I can get all resulting polygons, but I need to add intersection tests with original
geometries to get the labels
Another approach is with OverlayNG, but all operations (intersection, union, A-B, B-A and symmetric difference) give me a partial result
and I did not find a way to avoid several ovelay computations to get the full result.

Thank you for your ideas,

Michaël
