[Paraview] adding existing VTK filter without recompiling

[Greg Ushomirsky]

Hi,

I'm trying to add an existing VTK filter to Paraview 3.2.1 for Windows
that I downloaded from Paraview.org. I'm trying to follow the
instructions on the wiki page
http://www.paraview.org/Wiki/ParaView:Extend. That page gives an
example of two XML files that would be needed to make the existing
vtkCellDerivatives filter accessible through the menus.  I followed
the instructions, made the two XML files, and them, as the
instructions suggest:

To load the XML file into the ParaView, we will go to menu File and
select Import Package. This will popup a dialog in which we can select
the appropriate XML file.

Well, I go to the File menu, but there is no Import Package option!!

So, do I really need to build paraview myself in order to add an
existing filter?  Or am I missing something in the instructions??
Sure, I could build a plugin, but that requires building paraview from
source as well.

thanks for the help,
Greg
