vtkCleanUnstructuredGrid description correction
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Documentation of http://www.paraview.org/ParaView3/Doc/Nightly/html/classvtkCleanUnstructuredGrid.html#_details and http://paraview.org/OnlineHelpCurrent/CleanUnstructuredGrid.html are outdated since revision 1.7 of vtkCleanUnstructuredGrid.cxx
Currently, the documentation states "Clean to Grid filter merges points that are within a tolerance of 1/100,000 of the length of the diagonal of the bounding box of the data set." But that's not true any more. Since revision 1.7 only exactly coincident points are merged.
A suggested patch is attached.
