[Paraview] Plugin to modify the current transfer function

[Utkarsh Ayachit]

Yes, you can indeed write a client-side plugin that updates the active
opacity transfer function. Your plugin can monitor pqActiveObjects
singleton to get access to the active representation and from that you
can access it's ScalarOpacityFunction. Look at pqColorMapEditor and
pqColorOpacityEditorWidget in ParaView 4.1.0 source to see how that
could be done.
