[Paraview] Multiple inheritance in filter writing

[John Biddiscombe]

Benjamin

What happens if you do this...

class vtkMyFilter: public vtkUnstructuredGridAlgorithm
//BTX
, public myThreadedFilter
//ETX

I think I've used that trick before (or something similar, I'll check). 
If that doesn't remove the offending method instantiation, then why not 
simply define a dummy method in your vtk class (as long as it is linked 
in, it should be ok).

int vtkThreadedFilterCommand(vtkClientServerInterpreter*, 
vtkObjectBase*, const char*, const vtkClientServerStream&, 
vtkClientServerStream& resultStream)
{
return 1 or 0;
}
