[Insight-developers] GradientToMagnitudeImageFilter name

[David Doria]

The filter GradientToMagnitudeImageFilter:
http://www.itk.org/Doxygen/html/classitk_1_1GradientToMagnitudeImageFilter.html

seems to have nothing at all to do with Gradients. A more appropriate
name seems to be something like VectorImageToMagnitudeImageFilter or
simply ImageMagnitudeFilter. I realize changing a class name is not
backwards compatible, but in a big version step (ITKv4) would
clarifying this make sense?
