[vtkusers] Coloring HedgeHog vectors

[Jesse Neri]

I am using vtkHedgehog to visualize vector data from a 
structured grid data set. I would like the color of the
vector line to be scaled to the length of the vector, and
not a particular scalar component of the vector. How do I pull this 
off?  Various combinations of inputs to the vtkHedgehog or the
polydatamapper have given solid colors, but not a color
scale.
