title: frabric js freedrawing, get a reference to the object draw
body: <p>When using fabricjs in free draw mode, you can brush paths. Is there a way to get a reference as object to these paths, immediately after it is drawn? Example on mouse up get the object:</p>
  
  <pre><code>canvas.on('mouse:up', function(options) {
      var lastfreedraw = options.getLastFreeObject();
  });
  </code></pre>
