it would complicate the already complex algorithm and once we start
adding callbacks *in* core mechanisms we notonly get a slow down but
also an endless list of additional subcallbacks and dependencies
I'll think about this anyway, but I suspect Hans is right, and that
there is no 'good' spot to insert callbacks within the line breaking,
and doing the whole thing in lua may well be the best solution.
Dear all,
Thank you very much for your answer! I suspected this kind of
difficulties, and I trust you know better than me if it's doable or not.
By the way, Hans, I heard you already reimplemented the TeX linebreak
algorithm in pure Lua, can your code be found somewhere?
Thank you!
