[gtkmm] Style: Virtual Functions: Correct reference counting errors.

[José Alburquerque <jaalburqu src gnome org>]

commit 61147cd5c2dcdff48611465dbf60f2f08454b083
Author: José Alburquerque <jaalburqu svn gnome org>
Date:   Mon Nov 1 13:22:42 2010 -0400

    	Style: Virtual Functions: Correct reference counting errors.
    
    	* tools/m4/convert_pango.m4: Remove the conversion from `PangoLayout*'
    	to `const Glib::RefPtr<Pango::Layout>&' so it doesn't cause reference
    	counting errors in the future.
    	* gtk/src/style.hg: Put the PangoLayout conversion in this file
    	locally for the draw_layout virtual function. Also correct a
    	conversion that could cause reference counting errors.
    
    	Fixes GNOME Bug #633689 (mario).
