[vtkusers] lighting coefficients

Hi Benj-

The SetColor() method in VTK is a convenience method that sets the ambient, 
diffuse, and specular color simultaneously. You probably want to set them 
separately.

void vtkProperty::SetColor(float R,float G,float B)
{
   // Use Set macros to insure proper modified time behavior
   this->SetAmbientColor(R,G,B);
   this->SetDiffuseColor(R,G,B);
   this->SetSpecularColor(R,G,B);
}

Will
