How do I successfully use the shift option of pspicture? In former times, referring to Herbert's book from 2004, pspicture had a single optional argument which was a single number. Since 2008 one may use shift. But in my MWE:
\documentclass{article}
\usepackage{auto-pst-pdf}
\begin{document}
Test
some text
\begin{pspicture}[shift=<* or whatever number](0,0)(4,2) %\psgrid
\psframe(0,0)(3,2)
\end{pspicture}
some more
\end{document}
the output is always the same, namely a frame which is aligned to the baseline.
So is there any way to align a pspicture vertically, say, center it to the baseline? Maybe the faulty behaviour is due to auto-pst-pdf?
PS: In case it matters, I'm using TeXlive 2016, freshly updated, on macOS.
