Since we're already this far diverged, and everything we do to the DIX
these days seems to just break Xprint rather than generate any benefit
whatsoever, have you thought about forking the codebase, deleting all
the unnecessary input/etc code, getting rid of the workarounds, and
actually having something usable?

Seriously, this is getting a bit out of hand.
