Don't know. Its been on my mind for quite a bit to try and disentangle
the ownership of the fonts since it messes with the "auto-install a font
for a language if we can't render it" feature, which is the same problem
as the embedded font case. IIRC trying to throw away the old fonts in
order to get the new fonts ends up regetting the old fonts first and all
sort of funtastic happiness.
