bug in vtkMergeFilter (+solution)

[alext at win.tue.nl]

  Hi all,

  There's a small but nasty bug in vtkMergeFilter.cxx, vtk 3.1.

  In method: vtkDataSet *vtkMergeFilter::GetVectors()
  the return should be:

	return (vtkDataSet *)(this->Inputs[2]);

  and not

	return (vtkDataSet *)(this->Inputs[3]);

  as it is in the current vtk 3.1. solftware.
  As it is, vtkMergeFilter crashes if one connects/disconnects its inputs in
  some random order.

  Hope that helps,

  Alex
