That is now done.  If you update from the mercurial repository, you
can add a list to the file

  <list name="VTKOutput_SwarmList">
    <param>picIntegrationPoints</param>
    <param>passiveTracerSwarm</param>
  </list>

and it will output both the regular material points and the tracers in
their own files.  I am attaching the latest version of galtest1.xml as
a full example.

To make a single paraview control file, compile and run
tools/generate_pvd.cxx.  To convert the particle files to csv, you can
use tools/vtk2csv.py (that requires paraview's python 'pvpython').

Let me know if this works for you.

Cheers,
