/** \class ImageScanlineIterator
* \brief A multi-dimensional iterator templated over image type that walks a
* region of pixels, scanline by scanline or in the direction of the
* fastest axis.
*
* The itk::ImageScanlineIterator is optimized for iteration speed and is the
* first choice for pixel-wise operations on an image.
* This iterator is preferred over the older ImageRegionIterator even when knowledge
* of the current line state is not desired because of its speed.
