We expect to remove the deprecated methods in VTK 8.0.
Derivatives
-----------
VTK has a C/row-major ordering of arrays. The vtkCellDerivatives
filter was erroneously outputting second order tensors
(i.e. 9 component tuples) in Fortran/column-major ordering. This has been
fixed along with the numpy vector_gradient and strain functions.
Additionally, vtkTensors was removed as this class was only
used by vtkCellDerivatives and was contributing to the confusion.
