This is fundamentally extremely hard, because PostScript is a much more
powerful language than HPGL.  At the very least, it would require a
complete PostScript interpreter, plus some interesting design challenges
in how to implement, say, area filling in HPGL.  A simple translation
from HPGL to PostScript is no big deal, but vice-versa "there just ain't
no easy way".
