title: CORS issue when using fabric.fromUrl
body: <p>I am integrating fabricjs with angularjs application. I am pulling an image from a third party source (which is not in my control). I wish to perform some actions on it like: filtering, adding to canvas, storing to canvas and reloading from canvas.</p>
  
  <p>I am using fabric fromurl call with crossorigin but it fails everytime.</p>
  
  <pre><code> fabric.Image.fromURL('http://img.fkcdn.com/image/dining-chair/b/g/y/fidcbennywncsach-1-cedar-pine-devdar-home-cherry-white-original-imae9fsfbkxrgebt.jpeg', function (img) {
      canvas1.add(img.set({
          left: 50,
          top: 50,
          angle: 30
      }));
      console.log('CORS enabled + crossOrigin property - DataURL: ', canvas1.toDataURL());
  }, {
      crossOrigin: 'Anonymous'
  });
  </code></pre>
