title: Canvas scroll in wpf when scaled transformed
body: <p>I have customized a canvas to support the zooming. I am doing this by scale transformation.
  I have scroll viewer wrapped around canvas but scroll bars are not visible when canvas is zoomed.</p>
  
  <p>I came to know that scale transformation does not changes the actual size of the UIElement that is why scroll bars are not visible when canvas is zoomed.</p>
  
  <p>Is there any alternate solution to this? </p>
