Remarks
This answers a different question from Projection2, which builds the segment joining two shapes. Nothing is built here: one of the shape's own edges is handed back, whole, the one lying nearest the probe.
The probe is always a single primitive — a point, a segment, a circle or an arc. A shape that is itself made of edges is not offered, because the nearest edge of one such shape to another is really a pair of edges, and that is a different answer from the one this name promises.
Each edge is measured on its own, so a probe lying inside a closed shape still names the edge nearest it rather than reporting nothing, which is where this parts company with Distance2. Where two edges are equally near — and a probe crossing the outline touches several at nothing at all — the earlier one in the shape's own order wins, so the answer does not drift from one run to the next.
