title: Animated GIF in ImageList / TabPage
body: <p>I'd like to show an animated GIF as the tab image on a <code>TabPage</code>.</p>
  
  <p>If I add my image to an <code>ImageList</code> and use the <code>TabPage.ImageIndex</code> property, it only shows the first frame (and doesn't animate):</p>
  
  <pre><code>ImageList imageList = new ImageList();
  imageList.Images.Add(Properties.Resources.my_animated_gif);
  
  tabControl.ImageList = imageList;
  tabPage.ImageIndex = 0;
  </code></pre>
  
  <p>A few forums on the net also suggest <code>ImageList</code> doesn't support animated GIFs.</p>
  
  <p>Is there an easy way to display an animated GIF as an image on a <code>TabPage</code>? Do I have to owner-draw and animate the image?</p>
