patch of the night

I don't think it should activate the buttons, Instead I've made a patch to just scroll, like when you click the arrows, the input only GdkWindow is in case you scroll in an area not covered by any button.

Last try for tonight

New patch, doesn't try to resize the GdkWindow if the widget is unrealized, adds some path button edge checking to gtk_path_bar_scroll_[down|up] and removes the first parameter in those 2 functions, it was unused.

Any chance to get this in before 2.14?

Very clever to put the input-only window under the buttons.  Thanks, Garnacho, I just committed this to trunk and gtk-2-12 :)

	Fix http://bugzilla.gnome.org/show_bug.cgi?id=417389 - Make the
	scrollwheel work in GtkPathBar.

	* gtk/gtkpathbar.h (struct _GtkPathBar): New field event_window.

	* gtk/gtkpathbar.c (gtk_path_bar_realize): New function.  Create
	an input-only window, event_window, which we'll use to capture
	scroll events.
	(gtk_path_bar_map): Show the event_window under the rest of the
	windows, so it will be a catch-all for unhandled events.
