Allow vtkGhostType to be displayed in the GUI as a selectable array for filters
For at least the Image Data to Uniform Grid
filter we need to be able to select vtkGhostType
array in the GUI. See the discussion at https://discourse.paraview.org/t/xml-specification-questions-for-a-filter/2641. It's currently not being shown due to vtkPVDataSetAttributesInformation.cxx
ignoring it in vtkSkipArray
.
