No, its not deprecated. It's an important feature! It might have been
broken in some cases in the CVS before yesterday. (It was broken due
to some sorting problem of the attributes -- it should work now
again.) And to your question: text.vshift(0.5) should work. It is the
same like text.vshift.middlezero; text.vshift.char is removed in CVS
since it was not needed anymore after some cleanups.

Or you take a look at the box align methods ... linealign and
circlealign. It can perform more complicated alignment tasks very
well.

Have you seen the text style of the graph module? I do know this code
is not documented. I'm working on a cleanup and documentation of the
hole graph module and it goes well, although it takes a long time. For
the moment this code to take a look at is all I can offer ... but it
sounds like you want to do something simular. The test_graph.py in the
functional test directory uses this code and should be working in the
current state. But I'm currently doing xy-graphs only, although many
things are designed to work for different graph geometries as well ...
we'll see in the future.
