The "SetScalars" method already exists and is more flexible than
SetColors would be, because there are several ways that scalars can be
used.

Also, in the mapper you can specify that a particular named array will
be used to color your data (though I forget exactly what the method is
called).  This is even more flexible, since you can have several color
arrays and switch between them.
