Charles,
bbox() is indeed tricky! Try doing it on rotated text, or worse, text
on a path! However, your problem may only be a timing issue -- Batik
only knows the bbox once the text has been rendered, and in your
example there's probably not time for the renderer to have done its
work when you interrogate the properties.
