[Paraview] Problem in creating slice from vtkMultiBlockDataSet with cell data

[OSHIMA Takuya]

Yes, since the datasets >= 1 are surface representations of dataset 0,
each surface dataset and the corresponding surface part of dataset 0
share the same surface points. i. e. Each surface has its own
vtkPoints, but the point coordinates are exactly the same as the
surface points of the dataset 0.
