title: WPF TextBlock font resize to fill available space in a Grid
body: <p>I have some text that is displayed at run time in a textblock. I want
  the font size to be the biggest it can be to fill the area that is
  given. I think I have the textblock setup correctly to "autosize" and
  I try to increase the font size till the textblock is bigger than than
  its parent then decrease the font size by 1. The problem is I can't
  get the control to redraw/recompute its size.</p>
  
  <p>Is the a better way to do that? Or is there a way I can make my method work?</p>
