Implement vtkHigherOrderQuadrilateral::Derivatives
vtkHigherOrderQuadrilateral::Derivatives
and vtkHigherOrderCurve::Derivatives
for Lagrange and Bézier cells were not implemented and were not returning warnings when they were called.
This MR implements vtkHigherOrderQuadrilateral::Derivatives
, and return a warning for vtkHigherOrderCurve::Derivatives
.
In addition, I have done some minor cleaning in the Derivatives
functions of some other cells
