title: FileSaver.js with a Fabric canvas
body: <p>I was trying to use FileSaver.js with a Fabric.canvas object, but it seems that Fabric js has no blob option.</p>
  
  <p>I'm using the Meteor framework by the way.</p>
  
  <p>How can I export a Fabric canvas without using the basic canvas.toDataUrl ?'</p>
  
  <p>Thanks :)</p>
