[Paraview] color by vectors

[Wylie, Brian]

All,
 
Color by vector magnitude IS the default. So Dominik must have an old
version of ParaView.
 
(Advanced note: color by vector magnitude is not the default for volume
rendering.... this is because for volume rendering, the magnitude has to
be computed and added to every cell in the dataset...)

	Unless I am missing something, you can color by magnitude
without having to compute it with a calculator. Simply go to "Edit Color
Map" and change which component/magnitude the surface is colored by. I
guess it is an unexpected location to have that setting. We should
probably change the button name to something like "Edit Color
Settings...". We will change the default to be magnitude in the next
release.
