I am creating an unstructured mesh by hand:

	  newid = output->InsertNextCell(VTK_TETRA,pids0);
	  output->GetCellPoints(newid, pids1);

I am astonished to find that the retrieved pids are totally different
(not e.g. only shuffled) than the fed ones. The number of ids in both
lists is the same (4). The documentation isn't very informative here. Is
this unintuitive behavior really to be expected?

Best regards,
Dominik
