Micha,

I have 2 problems with respect to pdf output:

1. it looks as if the pdf output is mirrored with respect to the
    computer screen (depth?). See the attached files: the png file
    looks fine contrary to the pdf file.

2. the above files have been generated with Qt-3.  I am getting
    crashes and X-server messages when using Qt-4.

Note: the problems occur at least on several Linux systems with
QwtPlot3D wrapped by PyQwt3D.  This may be the reason for the second
problem, but IMO not for the first.
