title: Why FontStretch does not work in WPF?
body: <p>I am trying setting <strong>FontStretch</strong> property on a TextBlock in WPF but it seems that it does not work. I tried Expanded, Condensed, etc. but the text appearance does not change.</p>
  
  <p>I am working on Windows XP with Framework 4.0 and tested both with Verdana and Arial.</p>
  
  <p>Does it work only on Windows 7 or only with some specific fonts?</p>
  
  <p><strong>EDIT</strong>: If it does not work with all fonts, is there a list of fonts that support this feature? Or is it possible to modify a font like Verdana/Arial to support it?</p>
