+    desktop: Add configure event handler for desktop resize
+    
+    desktop need to resize its work area when window manager decorate its
+    window. Originally it is done by the hook in root window PropertyNotify
+    event handler, i.e. net_workarea_changed () routine. However, for unknown
+    reason, the PropertyNotify event does not deliver to the root window,
+    thus this routine does not work.
+    
+    this patch fix this issue from another side. Since window manager will also
+    send configure event to desktop window after decoration, it also works to do
+    it in configure event handler.
