I can't speak at all to why some widgets synthesize such events and  
others don't.  However, there is a crucial difference between  
GtkImage/GtkHBox/GtkLabel, etc., and GtkDrawingArea - the latter has  
its own GdkWindow, while the former do not (at least as far as I  
know).  Whether this has any connection to the explanation, I'm not  
sure, but it seems like it might (having not dug in to the code).
