title: OpenCV window in fullscreen and without any borders
body: <p>In OpenCV when displaying an image with:</p>
  
  <pre><code>cvSetWindowProperty("displayCVWindow", CV_WND_PROP_FULLSCREEN, 
  CV_WINDOW_FULLSCREEN);
  </code></pre>
  
  <p>There is a small border around the full screened window if anyone ever noticed. Is there a way to get a rid of this? </p>
  
  <p>Screenshot showing border of window when in full screen mode. <strong>Note</strong>: the screenshot was cropped to show only top-left corner</p>
