<a name="RBDisplayPage.description"></a><h2>Description</h2>
<p>This is the base class for items that appear in the display page tree and can
occupy the main display area.  Sources and source groups are display pages.
Other types of display, such as music visualization, could be implemented as
display pages too.</p>
<p>The display page object itself is the widget shown in the main display area.
The icon and name properties control its appearance in the display page
tree, and its location is determined by its parent display page, the sorting
rules for its source group (if any), and insertion order.  The visibility property
controls whether the display page is actually shown in the display page tree at all.</p>
