In the case that a cell has the same value on all its nodes the contour 
does not pass through this cell. So there is nothing to draw in that 
case. If you had a entire data set of cells with the same value on all 
its nodes, then by extension, there is nothing to draw as no contour 
intersects any cell.

Caveat, I am not a graphics guy, just reading up on the algorithms 
described in the VTK text. YMMV :)
