Description Ian 'Hixie' Hickson 2014-05-09 18:47:05 UTC 
This:

   var img = new Image();
   img.src = url;
   img.onload = function () {
     promise = createImageBitmap(img);
     // ...
   };

...is more complicated than necessary. Let's at least make it as simple as:

   var img = new Image();
   img.src = url;
   promise = createImageBitmap(img);
   // ...
Comment 1 Ian 'Hixie' Hickson 2014-09-30 17:41:27 UTC 
It'll eventually be:

   var img = new Image();
   img.src = url;
   var promise = img.loaded.then(function () { return createImageBitmap(img); });

...which is probably good enough.
