Im not sure I understand. Is it your contention that implementing at the
GTK level will break previous theme engines? Or are you saying that
existing theme engines will not be able to handle the additional state?

It seems to me that nothing should break because existing code should
simply ignore states it doesnt understand. If there are problems
introducing new states, then 2.4 is a good time to introduce them,
correct?

It would be a lot quicker for you to implement it, but I suppose your
plate is already quite full. :) If its up to me I cant promise it'll be
done any time soon, since school will be starting up again.

ps.Thanks for the link to the Theme engine tutorial (exactly what I was
looking for!) and bug report. I was going to leave a comment, but I cant
login to bugzilla.gnome.org today for some reason. It wont even email me
my password... I was going to log a bug regarding the GTK tutorial as
well.
