  It will update renderer and camera when window is resized.</p>
  
  <h1>Usage</h1>
  
  <p><strong>Step 1</strong>: Start updating renderer and camera</p>
  
  <p><code>var windowResize = THREEx.WindowResize(aRenderer, aCamera)</code></p>
  
  <p><strong>Step 2</strong>: Start updating renderer and camera</p>
  
  <p><code>windowResize.stop()</code></p>
