[Paraview] vtkBoxWidget2 RotationEnabledOff doesn't work

[Jorge Peña]

Hello Eric,

I figured out after reading the source code. I couldn't find any use of these 
variables, but still I wasn't sure if there was some paraview/cmake magic xD.

I'm using 3.8.1 and yesterday morning I finally decided to subclass 
vtkBoxRepresentation to vtkNonrotatingBoxRepresentation and provide a new 
widget with the ADD_3DWIDGET macro (although I needed to duplicate and modify 
some xml definitions to get it working). Anyway, thanks for answering my 
question. I will take into account if I decide to update Paraview in a future.

Cheers.
