When loading in Load_Chain{Sub,Pos}ClassRule, the limit we have only
Tue Apr 15 11:49:39 2003 Owen Taylor <otaylor@redhat.com> * pango/opentype/ftxg{sub/pos}.c: When loading in Load_Chain{Sub,Pos}ClassRule, the limit we have only applies to the input ClassDef table. Fixes problem with Arial Unicode. Much help from Noah Levitt in tracing this down.
