<p>Adds the given clip to the layer. Sets the clip's parent, and thus
takes ownership of the clip.</p>
<p>An clip can only be added to one layer.</p>
<p>Calling this method will construct and properly set all the media related
elements on <em class="parameter"><code>clip</code></em>
. If you need to know when those objects (actually <a class="link" href="GESTrackElement.html" title="GESTrackElement"><span class="type">GESTrackElement</span></a>)
are constructed, you should connect to the container::child-added signal which
is emited right after those elements are ready to be used.</p>
