Spec
https://html.spec.whatwg.org/multipage/scripting.html#dom-canvas-toblob
Summary
Creates a Blob object representing a file containing the image in the canvas, and invokes a callback with a handle to that object.
Motivation
Currently, the html5 canvas element has a toDataURL method, which outputs a DOM string representing the backing bitmap. With the File API now widely implemented, it is appropriate to add a similar getBlob method, one which would return a Blob object. Passing Blob pointers around is quite a bit more efficient than passing large base64 encoded strings.
