According to the documentation
<http://www.vtk.org/doc/nightly/html/classvtkIdList.html#a7e1b87799a2b013b218350644a904efd>
SetId requires memory allocation before using this command, this could
be done over the SetNumberOfIds() command.
Or you may use InsertId
<http://www.vtk.org/doc/nightly/html/classvtkIdList.html#a0b601275c162f3637773650eef2bf755>,
range checking and memory allocation will done automatically.
