[Paraview] export to vectorial image format

[Sven Buijssen]

Hi,

I happen to have a small patch for the git master branch that adds vector
graphics output (EPS, PS and SVG) to the Save Screenshot dialog and uses
vtkGL2PSExporter as a backend, too. Actually, it's just an updated version of
the patch for this matter I posted on this list back in 2007. But as holds for
the Python approach it has a few drawbacks:

* Only 3D View support
* Builtin mode and client/server mode support (but using merely 1 server
process, empty file when using more)
* No support for Manta/EyeDom/other views
* No multi-view support
* No support for mandelbrot source
* No support for text/annotate time source (a rectangular box is drawn instead),
one can resort to a 3D Text source, though
* No support for Volume rendering
* No support for Slice representation (try Surface representation of a slice
filter output)
* No support for PointSprite representation
* No support for SurfaceLIC representation, even crashes ParaView on export
* In display tab of object inspector, "Interpolate scalars" needs to be ticked
off for every visible object; otherwise object is rendered gray
(see http://www.vtk.org/Bug/view.php?id=1630)
* Requires an old version of the colorbar implementation or colorbar will be
rendered gray

So, don't get your hopes up too much about vtkGL2PSExporter.
