Seems strange to me. But no more strange than the interface...

If someone can demonstrate the proper usage here (if this is not a bug):
http://www.itk.org/Wiki/ITK/Examples/ImageProcessing/AddPixelAccessor

that would be great.

Also,

grep -ri AddPixelAccessor *

makes me think that this isn't used in any tests... probably a bad thing :)
