[Insight-developers] CastImageFilter

That's sound pretty reasonable. A Functor will allow to reuse most of 
the code
and easily generate CastingFilters on the fly.  

Adaptors are still around by not all Iterators support them.

For this particular case using the "ImageRegionIteratorWithIndex" will 
allow
to use an adaptor smoothly. Casting was the original motivation behind 
Adaptors
and PixelAccessor so in principle that should work fine.
