title: Fabric.js loadFromJSON width/height properties deserialization
body: <p>I have a problem with Fabric.js.</p>
  
  <p>When I'm trying to save fabric canvas like this:</p>
  
  <pre><code>var data = JSON.stringify(self.canvas.toJSON(['width', 'height']))
  </code></pre>
  
  <p>I get well serialized json with <b>height</b> and <b>width</b> properties.
  But when I'm trying to deserialize it like that:</p>
  
  <pre><code>self.canvas.loadFromJSON(data, function () {
      self.canvas.renderAll();
  });
  </code></pre>
  
  <p>All objects init fine except <b>height</b> and <b>width</b> properties.</p>
  
  <p>I saw deserialization example: <a href="http://jsfiddle.net/fmgXt/3/" rel="nofollow">http://jsfiddle.net/fmgXt/3/</a></p>
  
  <p>If I add to json <b>height</b> and <b>width</b> properties its ignores with deserialization. </p>
  
  <p>But if I set them into code - it also works well. Am I missing something? </p>
  
  <p>At <a href="http://fabricjs.com/docs/fabric.StaticCanvas.html#loadFromJSON" rel="nofollow">http://fabricjs.com/docs/fabric.StaticCanvas.html#loadFromJSON</a> I didn't find any mentions for loadFromJSON about includedPropertiesNames list or something like that.</p>
