title: How to clip content to an ellipse in a Windows Store app
body: <p>I am working on a Windows Store App and would like to clip some content to an ellipse/circle. The result should look like this:</p>
  
  <p><img src="https://i.stack.imgur.com/GaHJp.png" alt="enter image description here"></p>
  
  <p>The content could be a StackPanel or Grid for example using TextBoxes or other controls. </p>
  
  <p>UIElements have a Clip property but this can only be set to an RectangleGeometry and not a other shapes like ellipses.</p>
  
  <p>Is this possible in XAML for Windows Store Apps?</p>
