[Paraview] Transformation extraction from Transform filter

[Utkarsh Ayachit]

The "Transform" property is a vtkSMProxyProperty. Use GetProxy(0) to
get the actual source proxy that produces the transform while is the
("extended_sources", "Transform3") proxy. It does not have API to
access the transform directly, however. You can only get the
scale/translation/rotation values.
