What I usually do is generate eps/ps with cairo and convert that to
emf/wmf using one of the hard-to-find open-source converters available
on the web. There are a couple of converters there:

I considered implementing my own emf/wmf backend for cairo using
microsoft's released specifications but I don't know how legal that
would be: if someone is willing to look at this
http://msdn.microsoft.com/en-us/library/cc230514.aspx and tell me
whether it is legal to use it for a GPL implementation of a wmf/emf
generator, I would be happy to give this a shot in some of my copious
spare time.
