[Paraview] Paraview v5.1.2: SurfaceLIC & software rendering issues

[Benson Muite]

Frank,

Will see if can generate an example data set, in case am able to do so, 
can I redistribute the file (in particular would like to show several 
students how some of these parallel computing packages are used in 
industry)? Line 640 makes it difficult to re-distribute.
