    Stop using deprecated method free_colors() (#652044)
    
    Gtkmm releases 2.7.1 in July 2005 and 2.8 in September 2005 deprecated
    Gdk::Colormap::free_colors() and replaced it with
    Gdk::Colormap::free_color().  The oldest distribution currently
    supported is RHEL / CentOS 5.9 with gtkmm 2.10 so just unconditionally
    replace.
    
        ANNOUNCE: gtkmm 2.7.1

        ANNOUNCE: gtkmm and glibmm 2.8

    Bug #652044 - uses deprecated APIs
