Once I moved VectorMagnitudeImageFilter to ImageIntensity, the test
complained that it could not find
GradientRecursiveGaussianImageFilter.h (because it is in the
ImageGradient module). In this case I can just manually create a
vector image in the test, but is there a way to handle this? Or can
you absolutely not use anything from one module in another?
