        Part of #101079:

        * pango/opentype/ftxopen.c (Load_Lookup): In extension subtables,
        offset is relative to the extension subtable, not the original
        table. (Greg Aumann)

        * pango/opentype/ftxgpos.c (Load_BaseArray): When reading BaseAnchor,
        skip offsets that are zero.  Works around bug in Doulos SIL Regular.
