I am afraid that there is currently no easy solution, you have to go over
all the "new" faces and re-initialize your data.  This is not too hard
since in this case you only have to walk around the new vertex.

A nicer solution could be to introduce some visitors in algorithms like that,
but it's not done at the moment.
