[vtkusers] XDR support

[walizada at ucalgary.ca]

 Hi,
 
 I've check the archive and couldn't find any mention of this.
 
Does vtk support the XDR format? I'm pretty new to vtk so I'm not
 sure which classes may be relevant. I would like to know if vtk
 has a Reader class that can read in XDR data, or would I have to
 use the functions defined in /usr/include/rpc/xdr.h to convert the data
 and then pass it on to vtk.
 
 thanks for your help,
