I think that in all cases ITK when writing data is writing in the proper 
units. Therefore the slope/intercept should simply be set to 1,0. I 
don't see any case where the image would be loaded/manipulated in the 
non-units (aka raw stored pixel value, before slope/intercept) then 
written to disk.
