Introduce it as a new/separate class?  (And eventually phase out the
current class)
Obviously there's maintenance overhead to this approach, but it's
what I often have to do when an existing class needs a major overhaul
and I don't want to break existing users.

[ OTOH, isn't all the User Font stuff new in 1.8, and you're only on
1.7?  If so, can't you still change it?  That's the only reason I
opened this discussion... ]
