[Paraview] Animated Parameter Annotation

[Utkarsh Ayachit]

Hmmm, very interesting; it could be done using python.
Here a plan:

* create a simple "Text" source proxy.
* add observer to the animated properties vtkCommand::ModifiedEvent.
* in the call-back, change the text of the text source proxy to match 
the value of the property.

A caveat: python event-observers/callbacks don't work in python shell in 
the paraview GUI. However, should work fine with pvpython/pvbatch.
