        Update of GPOS and GSUB support to OpenType 1.3
        (From FreeType, Werner Lemberg, 2001-08-08)

        * pango/opentype/ftxopen.h: Add RIGHT_TO_LEFT LookupFlag

        * pango/opentype/ftxgpos.c (GPOS_Instance): Add 'first'
        member to mark the beginning of a chain of cursive connections.

        * pango/opentype/ftxgpos.c (Do_String_Lookup): If the
        RIGHT_TO_FLAG flag is set, shift cursive chain up so
        last glyph is on the baseline.
