[Paraview] viewing properties that are discontinuous across cell boundaries

[Peter J. Bismuti]

We have developers interested in viewing properties that are discontinuous 
across cell faces/edges.  It could be higher-order derivatives, or the 
basis-functions themselves are discontinuous.  

Can PV do this, and if not, how difficult would it be to implement?  I'm 
assuming it would require some type of tesselation, or, a programmable 
vertex/fragment shader.   

Thanks in advance
