Benchmark: Canvas context2d: Image vs ImageBitmap vs Canvas (new)

Script Preparation code:

var img = new Image();
var imageBitmap;
var doneLoading = false;
var canvasImage = document.createElement('canvas');
canvasImage.width = 640;
canvasImage.height = 480;
var canvasImageBitmap = document.createElement('canvas');
canvasImageBitmap.width = 640;
canvasImageBitmap.height = 480;
var canvas = document.createElement('canvas');
canvas.width = 640;
canvas.height = 480;
var canvasCanvas = document.createElement('canvas');
canvasCanvas.width = 640;
canvasCanvas.height = 480;

var ctxImage = canvasImage.getContext('2d');
var ctxImageBitmap = canvasImageBitmap.getContext('2d');
var ctx = canvas.getContext('2d');
var ctxCanvas = canvasCanvas.getContext('2d');

async function globalMeasureThatScriptPrepareFunction() {
  return new Promise((resolve, reject) => {
    img.addEventListener('load', function() {
      Promise.all([
        createImageBitmap(img)
      ]).then(function(images) {
        imageBitmap = images[0];
        doneLoading = true;
        console.log("bitmap preparation done");
        resolve(true);
      }, false);
      ctx.drawImage(img, 0, 0);
      console.log("canvas preparation done");
    });

    img.src = 'https://1.bp.blogspot.com/-52MtzD0GfX0/WvP52CL1WjI/AAAAAAAAOVw/_OpK4JHeWK01d-7IiZ6vzojYGhXqLRXrACLcBGAs/s1600/EMxediL.jpg';
