Hi.

It seems that point data from `vtkProbeFilter` (e.g. `MetaImage` from probing an MHA with a VTP) is lost when processed afterwards with `vtkSelectEnclosedPoints` (only contains `SelectedPoints` and `vktValidPointMask`). Since there is no specific “copyPointData” option and according to [https://gitlab.kitware.com/vtk/vtk/blob/master/Filters/Modeling/vtkSelectEnclosedPoints.cxx#L227-230](https://gitlab.kitware.com/vtk/vtk/blob/master/Filters/Modeling/vtkSelectEnclosedPoints.cxx#L227-230) I would expect that all point and cell data is copied, I suspect this might be a bug. What could be the reason that [https://gitlab.kitware.com/vtk/vtk/blob/master/Filters/Modeling/vtkSelectEnclosedPoints.cxx#L227-230](https://gitlab.kitware.com/vtk/vtk/blob/master/Filters/Modeling/vtkSelectEnclosedPoints.cxx#L227-230) does not copy over `MetaImage` point data?

PS: I saw that there is also `vtkExtractEnclosedPoints` in v8.2.0.rc2, however both `vtkSelectEnclosedPoints` and `vtkExtractEnclosedPoints` never finish running with v8.2.0.rc2, independent of using TBB or not, when I use them in my VTK-CLIs:

Many thanks for any help or hints.

Seems to be a bug, see:
