[vtkusers] Light without shadows

[Jose Luis Pina]

>Hello:
I have some glyphs (vtkArrowSource), coloured according the vectors in each 
point, but the shadows created by the light, change the real color 
associated with every arrow, I tried with vtkLight and vtkLightKit, 
TwoSidedLighting with the rendere but I can't do.I wonder if is posible 
ilumination without shadows or with a minimal shadow that keep the real color.
Thanks in advance.
