GtkSharp/gtk/PrintContext.custom
Mike Kestner 8a29f46b8f 2008-04-16 Mike Kestner <mkestner@novell.com>
* gtk/Gtk.metadata: hide PrintContext.get_CairoContext.
	* gtk/PrintContext.custom: manual get_cairo_context implementation.
	Mono.Cairo assumes it is wrapping owned references, so we need to 
	take a ref out on the returned cairo_t pointer.
	* sample/GtkDemo/DemoPrinting.cs: dispose the CairoContext in
	to be a good citizen and avoid warnings.
