[vtkusers] Improving rendering speed

[N Smethurst]

One other thing to add to this story about normals calculation time. When I 
timed a

surfl(X,Y,Z)
shading interp  %Gouraud

in Matlab, it took much less time to execute for the same size surface, 
even though it has to calculate the normals for this type of plot. This 
makes me wonder if the normals calculation is not well optimised in VTK.
