[Paraview] loading multiple state-files without hiding and resetting already loaded objects

[Cory Quammen]

Hi Roman,

It turns out ParaView was not designed for this use case because of
certain difficulties discussed here:

https://gitlab.kitware.com/paraview/paraview/issues/17442

In your Python script, you could manually cash all the properties of
the existing representations and restore them after loading the most
recent state file.

The functions

reprs = GetRepresentations()
repr = reprs.values()[0]
props = repr.ListProperties()
GetProperty(repr, props[0])

would be helpful for this.

Cory
