Offset to MarkAttachClassDef is offset to table, not offset to offset to 

Wed Aug  7 12:32:39 2002  Owen Taylor  <otaylor@redhat.com>

        * pango/opentype/ftxgsub.c (TT_Load_GSUB_Table):
        Offset to MarkAttachClassDef is offset to table,
        not offset to offset to table.

        * pango/opentype/ftxopen.c (Get_Device): Handle
        NULL device tables which we represent with
        d->DeltaValue == NULL.
