[Paraview] Gradient (Unstructured) filter

[Alessandro A. Bellina]

When I look at a cross section of the domain using "plot over line", places
where the gradient should be negative, it is always positive. In addition,
the label for the color bar says "Gradient Magnitude" even though that is
not the filter I selected.
