select signal on list items and focus tracker

["Padraig O'Briain" <Padraig Obriain Sun COM>]

While running our current ATK and GAIL implementation against the GTK test 
program testgtk I noticed that some objects were reporting a position of (-1, 
-1).

It transpires that these objects are list items and this happens when the 
"entry" button which causes a window containing a GtkEntry and GtkCombo to be 
displayed.

I checked the GtkObject flags field for these and compared it to the the flags 
fields of other widgets. The difference seems to be that GTK_MAPPED is not set 
for GtkListItem in this case.

I think that a select signal on a GtkItem should not be regarded as receiving 
focus unless the widget is mapped.
