It uses a lot of memory. Each char has several double float associated with it.

I look at the Stix font site every now and then and I will put them in cl-typesetting as
soon as they are available.

Yes, as far as math typesetting is concerned, AFAIK everybody uses TeX inspired
algorithms.

Great :)

If you want, I can give you a contact with a friend of mine who is TeX expert as well as
Lisper. He would probably be able to help you if he has some time ;-)
