in mkii we had math vectors and one could have many different vectors
active at the same time (so, lucida alongside lm and others); in mkiv we
assume unicode math
I can probably make something for mkiv but the question is: is it worth
the trouble and complication. Eventually all these math fonts will be
open type anyway.
