I looked at 0.37 and found no such support. You can, I think, specify
arrow heads directly by modifying the XML. But even then, the lack
of EPS output makes it unsuitable for book illustration. For web
publishing png output is fine. Anyway, I like Dia much better
for the task.

Yes, I know autotrace but my figures were not so complex, and I think
it would cause more trouble than it is worth.

That would be fine. I myself have not much knowledge about this sort of software.
I think, however, it would be better to generalize Dia itself than to
fork.

I don't know the rules here in Europe, but indeed 70 years is long. It
may be suited for writers of novels, but technical books have usually
a quite short lifetime anyway. A shorter copyright time would also allow
publishers like Dover to reissue a book, that the original publisher
doesn't want or cannot afford to.

In fact, the complete content of the book will be available in an online
version. The online version is built from XML sources and features Java
applets and MathML and quote a few navigational niceties.

I can put some dia examples with its eps output online...
