Summary0013455: vtkCellDerivatives computes wrong results on quadratic quadrilateral cells
DescriptionWhen trying to calculate the fluid strain rates on second order quadrilateral elements the PV 3.14.1 ComputeDerivatives filter produced the wrong results. I was able to reproduce the bug with a simple ramp function in y-direction in PV 3.14.1 and PV 3.10.1, c.f. y-Ramp_and_ScalarGradient_X.png and y-Ramp_and_ScalarGradient_X.pvsm in attached zip file.

I attached a patch, which fixes the mentioned bug. I did not take care about efficency concerns, however.
