title: WPF Grid Column auto with some room to grow
body: <p>I have a Grid in WPF where the last column's size is Auto.  However, in that column is text that, when I mouse over it, turns from normal to Bold, making the text a little bit bigger (as bold text generally is).  The net effect is that the column gets bigger, moving all of the other content around, then smaller when I mouse away, moving everything else again.</p>
  
  <p>What I'd like to do is define my column width to have a little bit of extra but still be Auto width, so that when this resize occurs due to mouse-over it doesn't create such a jarring effect.</p>
  
  <p>I don't have any idea how wide it will be ahead of time; it can very quite a lot.  Obviously if you change the entry the column grows, but I just want to keep the bolding effect from causing a rapid grow/shrink every time my mouse gets too close.</p>
