matter-js can't find decomp when imported via ES6

[fiskhandlarn]

Since matter.js tries to evaluate windows.decomp directly when imported ...

var decomp = (typeof window !== "undefined" ? window['decomp'] : typeof global !== "undefined" ? global['decomp'] : null);

... and all imports are done before any other code is run, this (as implied by this example) didn't work for me:

import decomp from 'poly-decomp';

window.decomp = decomp;

import Matter from 'matter-js'; // eslint-disable-line import/first

matter-js was still evaluated before window.decomp = decomp, and thus var decomp would still be undefined.

This plugin should check for window.decomp first when it's needed (inside Bodies.fromVertices) or at least document this solution from @rykerrumsey.

I had the same problem but managed to resolved it by adding global decomp in webpack (the same as provided link). I also think it should be changed, back then I was very confused why my code does not work even after adding global decomp.
