Detailed Description

Chebyshev (LInf) distance between shapes.

Mirrors the shape coverage of distancel1.hpp, but for the LInf metric max(|dx|, |dy|) instead of L1. Implemented independently of L1 (no coordinate-transform trick relating the two metrics) – the two files happen to share the same overall shape-recursion structure because that structure only relies on convexity, which both metrics have, not on any relationship between them.
