// Coord is a way of storing a 2d integer vector (e.g. vec2i or similar) as a
// value type by packing it into a number. It will do what you want in a Map or
// Set, you can compare them for equality, and it should be free of alloctions
// (at least in Spidermonkey and V8, but probably anywhere else too).
//
// The downside is that it's a pain to debug, use, and it has ugly syntax. It's
// type safe (in typescript) tho.
//
// Each component is stored as a 15 bit (signed, 2's complement) integer. These
