[Paraview] Animated Parameter Annotation

[Kent Eschenberg]

Summary: I'd like to update a text object during a pvbatch animation so it can show the value of the cut plane being moved during the animation.

Works great but unfortunately obj contains the old value, not the one to which the animator has just changed. I think the new value is buried in obj somewhere but cannot discover how to get it.

My workaround: I ignore obj and use the current value from cutPlane.

Suggestions?
