Module polygon 

Structs

HalfSpace 🔒

Points kept by clipper are the ones with normal . point >= offset

Polygon 🔒

Convex polygon of the intersection, kept on the stack: this runs once per element per interface

Constants

MAX_POLYGON_VERTICES 🔒

A tetra cut by a plane gives at most 4 vertices, and clipping a convex polygon by a half space adds at most one, so four bounds can never take it past 8
