I'm asking for an easy way to use the same fonts with exactly the same size in both places, I do not really care how it is implemented. Maybe it is already possible and the only missing thing is the documentation to do so. I can do it via some pstricks hackery, and it sort of works, but the process is a bit indirect and not really comfortable.
