title: WPF Fonts.SystemFontFamilies doesn't return all expected FontFamilies
body: <p>For our WPF property grid, we implemented a FontSelector something like what is in Word 2007.  The FontFamily is in the first comboBox.  I'd expect that I would be able to populate this list by using <code>Fonts.SystemFontFamilies</code>.  This works mostly, but I end missing a number of expected entries.  I.e. I only get one Arial, in the word dialog there is there is only one listing for Arial.  In word, there is Arial, Arial Black, Arial Narrow, Arial Rounded MT, and Arial  Unicode Ms".  In another case, I expect Wing Dings, Wing Dings 2, and Wing Ding 3 but I only get Wing Dings.</p>
  
  <p>So how do I work through the FontFamily 'Arial', to add in the other ones I am looking for?</p>
  
  <p>(The above was for Win7, On vista I am missing some font families but the missing ones are different for vista)</p>
