[vtk-developers] Manual conversion of some Tcl to Python tests.

[Andrew Maclean]

I meant to add that I am also happy to write a vtkNamedColors class if you
guys think it would be worthwhile.
>From my viewpoint it would be great to have an alternative to things like:
SetColor(0.2,0.3,0.4).

I promise I will use "color" and not "colour" !
