[ITK] [ITK-users] ImageRegionIteratorWithIndex

[Jim Miller]

Image Iterators allow you to visit every pixel in an image (or image
region) with a prescribed pattern of access.  We use Image Iterators to
write generic code that can operate on 1D, 2D, 3D, and 4D images without
requiring the algorithm code to understand the dimension of the image.

The WithIndex variants of the Image Iterators are optimized to be able to
report the pixel position (Index) of the iterator.
