The Graphics2D export to PDF regarding fonts has a bit
of problems because Java is not very consistent with
the font dimensions. I could never figure out where it
gets the height values for the sanserif font if the
values come from Arial, for example.
In any case I would like to see a small, complete
program that I could run here.
