[Paraview] Custom Panel Force Accept

[Utkarsh Ayachit]

1) Are you sure the property is being changed? Compare the values of
the property berfore and after.
2) Are the VTK methods that should be called on the underlying filter
being called? Add breakpoints/couts and verify?
3) Are you calling this->Modified() in those VTK methods? VTK does not
reexecute a filter unless it is modified.
