<p>The display page tree widget is a GtkTreeView backed by a GtkListStore
containing the display page instances (sources and other things).  Display
pages include sources, such as the library and playlists, and other things
like the visualization display.</p>
<p>Display pages are shown in the list with an icon and the name.  The current
playing source is displayed in bold.</p>
<p>Sources are divided into groups - library, stores, playlists, devices,
network shares.  Groups are displayed as headers, with expanders for hiding
and showing the sources in the group.  Sources themselves may also have
child sources, such as playlists on portable audio players.</p>
