[dev-context] wrong paper orientation with pstopdf

[Mojca Miklavec]

Hello, Hans,

Do you remember some strange 90 degrees rotation in the gnuplot
module? I thougt that gnuplot did a strange job, but now I found out
that it was indeed pstopdf's fault.

The option
    -dAutoRotatePages=/None
should be either removed or changed somehow, otherwise landscape
figures rotate for 90 degrees, which is wrong.
