[Paraview] Scalar components and Python Calculator

[Sean Ziegeler]

I *think* that the _X, _Y, _Z notation is something that the Calculator 
does as a convenience.  I think in the Python calculator, you might have 
to access the components as an array index or use GetComponent() or 
something like that.  I don't see any documentation on the Python 
Calculator that help with that sort of thing, so you might have to 
experiment with it.
