I know direct printing of pdf works for many printers. My point is more about
having a demo driver that shows why the opvp approach is better
that other approaches, and also serves as coding example.
Other ideas - e.g. a vector driver that reads pdf and writes openoffice
format, would be useful to many, or even one that transform pdf's - e.g.
