<p>
Adds rule to a filter that allows files based on a custom callback
function. The bitfield <em class="parameter"><code>needed</code></em> which is passed in provides information
about what sorts of information that the filter function needs;
this allows GTK+ to avoid retrieving expensive information when
it isn't needed by the filter.</p>
