In Load_ChainContextSubst2, handle the case where an empty class
Fri Mar 15 01:35:56 2002 Owen Taylor <otaylor@redhat.com> * pango/opentype/ftxgsub.c pango/opentype/ftxopen.c pango/opentype/ftxopenf.h: In Load_ChainContextSubst2, handle the case where an empty class definition is represented by an offset of 0. * pango/opentype/ftxgpos.c: Same for Load_ChainContextPos2. * pango/opentype/{ftxopen.c,ftxgpos.c,ftxgsub.c,ftgdef.c}: Fix pervasive bug where on cleanups on failure of loading an array element, all array elements were freed, not just the ones that had been succesfully loaded.
