title: Resize a WPF window, but maintain proportions?
body: <p>I have a user resizable WPF Window that I want to constrain the resizing so the aspect ratio of the window stays constant.  </p>
  
  <p>Ideally I would like to constrain mouse location when the window is being resized by dragging a corner to positions that maintain the proper aspect ration.  If an edge is resized with the mouse, the other dimension should change at the same time.</p>
  
  <p>Is there a simple way to do this or a good on-line example that anyone knows of?</p>
  
  <p>If no better solutions come up, I'll post what I've done after I've refined it a bit.</p>
