[pstricks] Right-handed coordinates in pst-3dplot

[Joel Salomon]

I've been trying to get a right-handed coordinate system in pst-3d,
but I seem to be missing something,  The example below seems to put
the axis labels where they should go in a right-handed system, but the
dot position shows otherwise:

\documentclass{minimal}
\usepackage{pstricks}
\usepackage{pst-3dplot}
\begin{document}
\pagestyle{empty}
\psset{Alpha=30,Beta=15,RotSequence=zyx,RotY=-90,RotZ=-90}
\begin{pspicture}(-4,-4)(4,4)\psgrid
        \pstThreeDCoor[drawing=true,
                xMin=4,xMax=-4,%
                yMin=-3,yMax=3,%
                zMin=-4,zMax=4]
        \pstThreeDDot(1,1,0)
\end{pspicture}
\end{document}

The axis lines and labels are exactly where I want them, but
apparently setting xMin > 0, xMax < 0 does not make a right-handed
coordinate system.  What does, though?

Thanks,
