+Icon
+====
+
+Description
+-----------
+This patch gives tabbed an icon. This icon is the currently selected tab's icon.
+If the selected tab has no icon (or no tab is selected), use a (admittedly ugly) default icon.
+
+This patch supports both the new EWMH (\_NET\_WM\_ICON) and
+legacy ICCCM (WM\_ICON) ways of setting a window's icon.
