title: Display glut window on Qt widget / QWindow
body: <p>I am trying to configure one of the samples bundled in the OptiX 3.0.1 SDK to display in a Qt Widget.</p>
  
  <p>The sample currently renders to a glut window and makes use of glViewport. Is there a way that I can change the glut window to a Qt Widget or make the glut window display on a Qt widget?</p>
  
  <p>The sample makes use of a vertex buffer object:</p>
  
  <pre><code>glBindBuffer(GL_PIXEL_UNPACK_BUFFER, vboId);
  </code></pre>
  
  <p>I have created a class that inherits from QWindow. Is it possible to use the vertex buffer object to render to the QWindow?</p>
