\brief This driver produces output in PostScript, EPS and PDF.
\ingroup drivers
This driver produces output in one or multiple PostScript file(s) (*.ps), multiple
EPS (*.eps) and/or one PDF (*.pdf).
\todo DRIVERS: PDF is still raster and needs to be vector!
\note PDF is currently produced throgh <b>ghostscript</b>. This means it uses raster instead of
vector information to describe the graphics.
