Remarks

A GeoPolygon3 and a GeoFace3 could be cut in two and a GeoPolygon2 and a GeoFace2 could not, though the plane is where that is usually wanted. Everything already cut in the plane — segments, chains, loops — came back as lines; nothing came back as an area.

Nothing new is worked out here. The shape is laid flat in the world frame at z = 0, cut by the exact arithmetic Splition3 already holds, and projected back. Lifting adds a nought and projecting drops it, so the round trip costs no accuracy, and the two readings cannot drift apart because there is only one of them.

The cutter is a GeoLine2 read as the whole straight line through it, which is what a GeoPlane3 is to space: unbounded, and dividing everything into two sides. Its length is ignored — a segment crossing half the shape cuts all of it. Where a bounded cutter is meant, the cut line overload takes a chain that has to start and finish on the boundary.
