+      <title>Add backing store support</title>
+      <description>
+	<p>
+	  GTK+'s drawing model involves clearing to a background, and
+	  then drawing widgets on top of this. Without having
+	  backing-store support, this results in flickering in various
+	  situations. Backing store cannot be added widget-by-widget,
+	  because the drawing in a particular window is not confined
+	  to a single widget. Instead it needs to be added per GDK
+	  window. 
+	</p>
+	<p>
+	  The way this is done is by having
+	  <tt>gdk_window_begin_paint()</tt>
+	  and <tt>gdk_window_end_paint()</tt> functions that
+	  redirect all drawing to a particular window to an offscreen
+	  pixmap, and then copy that offscreen pixmap back onto the
+	  screen when the paint operation is done. The implementation
+	  of this is mostly complete in the <tt>gtk-no-flicker</tt> branch of
+	  GTK+.

+	<p>
+	  Currently, GTK+ has a large number of list and tree widgets
+	  (GtkList, GtkTree, GtkCList, GtkCTree), non of which are
+	  ideal. The GtkList and GtkTree widgets perform badly on large
+	  sets. (GtkTree widget is also quite buggy.) GtkCList
