[Paraview] Moving slice with particle

[Thorsten Hater]

Thanks for this! But contrary to my earlier optimism it seems not so 
easy to
use a slice filter in a programmable filter (I played mostly with the 
pvpython
  up to this point)
The python vtk module does not export ExtractVOI or ImageSlice filter,
the generic cutter does not work for me.
If I import paraview.simple a new connection pops up and PV itself is 
messed up,
so I can't use simple's Slice. Can I work around this behaviour?
