title: How to convert Drawing.FontFamily to Media.FontFamily
body: <p>I would like to use a <code>Media.FontFamily</code> to change a TextBox (WPF Element) font.</p>
  
  <p>First I use a <code>Drawing.Text.PrivateFontCollection</code>, and load a custom font with 
  <code>AddMemoryFont(IntPtr, int)</code> function.
  I only have the font in binary data, which is not installed the computer. (The font is embedded in a project's resources, but not in the same project).</p>
  
  <p>With this method, I only have a <code>Drawing.FontFamily</code>. I'm looking for a solution, and I wonder if it is possible to solve the problem with these ideas or others :</p>
  
  <p>Is it possible to directly convert a <code>Drawing.FontFamily</code> to <code>Media.FontFamily</code> ?
  Maybe can we create a Media.FontFamily from binary data ?
  Or is there a way to use a <code>Drawing.FontFamily</code> in to change a TextBox's font ?</p>
