[vtkusers] How to generate a surface normal glyph for a triangle cell

[Elvis Dowson]

Hi Miguel,
                      I searched the book for "surface normal" or  
"normal" but did not find any info on how to display the surface  
normal as a glyph.

I've got a surface normal, I've got an arrow glyph. Only the  
orientation is wrong. Is there some way to obtain the direction vector  
for a surface normal?

Best regards,

Elvis
