shortdesc: Show a magnified version of imager under the pointer
docs: >
  <p>This example makes use of the <code>postcompose</code> event listener to
  oversample imagery in a circle around the pointer location.  Listeners for this event have access to the Canvas context and can manipulate image data.</p>
  <p>Move around the map to see the effect.  Use the ↑ up and ↓ down arrow keys to adjust the magnified circle size.</p>
