[vtkusers] bug in vtkEdgeTable

[Claudia Goenner]

Hi!

I am using vtk 3.1.2 and noticed a bug in vtkEdgeTable. If you use
vtkEdgeTable::IsEdge it causes a segmentation fault if your index, being
the smaller pt id of your edge, is bigger than the TableMaxId. This can
be corrected by adding the following lines to vtkEdgeTable:IsEdge


  if ( this->TableMaxId < index ) {     //new check
    return -1;
  } else {
    if ( this->Table[index] == NULL )  //original code
    ...
  }
