Generating widget images offscreen?

[Joshua Outwater <Joshua Outwater sun com>]

Hi,
	I am trying to create an application that will create an instance of a 
widget (GtkButton, GtkLabel, ...), set a particular state, and then take 
a snapshot of the widget.  So far I am assuming I would use 
gtk_widget_set_state with the particular state I want to widget to 
render in.
	The problem I am running into is being able to create an offscreen 
window.  I could not find a good way to do this.  As far as I saw, 
GtkWindow doesn't have a GtkWindowType of "offscreen".  Theoretically I 
could use support methods to move it off into oblivion.  But what I am 
really looking for is a scratch window that will not show up in the 
window manager.  Is there an equivalent for this in Gtk?  Has someone 
done anything similiar?  I would be grateful for any recommendations.

Thanks,
