[Paraview] Cloud O'Points

[Dominik Szczerba]

I did such things but outside VTK/PV and for tets only. Worked very nice
and fast as poor man's volume visualization. With a very large number of
points you will get nice cloudy results, but this will also be slow at
some point. You would need to implement a filter adding N random points
to a tet with N proportional to the cell scalar. A key is a function to
pick a uniform random point in a cell. Takes some head scratching for a
tet, no instant idea about arbitrary cell shapes.
