[vtkusers] ConfigScalarLegend from python interpreter

[jck103 at soton.ac.uk]

In MayaVi there is a button titled "ConfigScalarLegend", from the window
that pops up one can reverse the look up table with a check box "Reverse
LUT" and can select "Show Legend" and "Shadow Legened".

Is it possible to select any of these using commands from a Python
interpreter, say IPython.

  Thanks,       James.
