commit 3a6a068c4be871e2973083d8d0debcd5dd64a1c9
Author: Murray Cumming <murrayc murrayc com>
Date:   Mon Nov 29 10:42:34 2010 +0100

    Scrollable, ScrolledWindow: Fix Adjustment reference counting.
    
    	* gtk/src/scrollable.hg:get_hadjustment(), get_vadjustment():
    	* gtk/src/scrolledwindow.hg: get_hadjustment(), get_vadjustment():
    	Use refereturn to fix the reference-counting on these, which was broken
    	since we changed Adjustment to be a Glib::Object instead of a Gtk::Object.
