Layer rendering can be manipulated in <code>precompose</code> and <code>postcompose</code> event listeners.
These listeners get an event with a reference to the Canvas rendering context.
In this example, the <code>postcompose</code> listener applies a filter to the image data.

<p>See the <a href="image-filter.js" target="_blank">image-filter.js source</a> for details on how this is done.</p>
