Online Photo Editing - FabricJS Masking

A while ago I tried implementing a photo mask tool in MockoFun which is based on FabricJS

Check out an working example: https://jsfiddle.net/codingdude/sk84xLh2/

The solution I came up was combining the built in fabric.Image.filters.BlendImage filter with a custom FabricJS brush. Here's a glimpse at my implementation of that.

(function(){

let cache = new Map();
let pending = new Map();

function fetchTextSync(url) {
  if (cache.has(url)) {
    return cache.get(url);
  }
  if (pending.has(url)) {
    throw pending.get(url);
  }
