title: How to add a shadow around a TextBlock in XAML
body: <p>I noticed a Windows Store app called PressPlay Video:
  <a href="http://apptivate.ms/apps/76/pressplay-video" rel="nofollow">http://apptivate.ms/apps/76/pressplay-video</a></p>
  
  <p>It is able to display text with a shadow all around the text (for subtitles and overlay).</p>
  
  <p>Since drop shadow effects aren't available in WinRT, I was wondering how to do it.</p>
