[vtkusers] Graph vertex coloring not working

[Jeff Baumes]

vtkGraphLayoutView does not support a special unsigned char array
named "color" for coloring vertices. You will need to use an array
with normal scalar values (e.g. a vtkIntArray) and then use
vtkViewTheme's point lookup table to set up the proper mapping of
integers to colors.
