[Paraview-developers] MFiX Reader Data Range issue

[Utkarsh Ayachit]

Another reason why the ranges may show up incorrectly when going back and
forth through timesteps is the "geometry caching". ParaView by default
caches geometries to enable flip-book animations so that when user plays
the animation in a loop, we don't update the reader to produce a new
timestep, instead we just cycle through rendered geometries. In that case
the ranges on the information tab can be incorrect too. I've pushed a
change to disable caching by default and warn users about the potential of
incorrect data ranges in the settings dialog (where one goes to
enable/disable geometry caching for animations).
