[Paraview] Python Cut Problems

[Utkarsh Ayachit]

If you save the output of the Cut filter into an ASCII vtp file or 
something, you'll notice that it saves out normals. The filters passes 
the normals from the input to the output, hence each line has associated 
normals.

One way to fix this is change the Representation to wireframe. In this 
more, lighting is disabled and hence there won't be any interference.
