        Reduce non-shared data (#168899, inspired by patches
        from Tommi Komulainen and Ross Burton)

        * pango/pango-color.c pango/pango-color-table.h
        tools/gen-color-table.pl: Redo storage of colors to
        use offsets into a static string rather than embedded
        strings. (Inspired by a patch from Tommi Komulainen,
        #168899)
