title: Canvas is clipped when size is too big
body: <p>I am using a canvas with the an <code>ImageBrush</code> to dispaly an image. I am setting the size of the canvas to the original size of the image so I can get the coordinates when I move the mouse etc.</p>
  
  <p>The problem is that when I put the canvas in a control (<code>Grid</code> for example) with a smaller size the <code>Canvas</code> is clipped.</p>
  
  <pre><code>  &lt;Grid&gt;
      &lt;Canvas Width="{Binding ImageWidth}" Height="{Binding ImageHeight}" &gt;
          &lt;Canvas.Background&gt;
            &lt;ImageBrush ImageSource="{Binding Image, Converter={StaticResource imgConverter}}"/&gt;
          &lt;/Canvas.Background&gt;
      &lt;/Canvas&gt;
    &lt;/Grid&gt;
  </code></pre>
  
  <p>Is there a way to keep the canvas size without being clipped?</p>
