[Insight-developers] ImageAdapter::GetPixel

Luis,

The ImageAdapter class provides two versions of GetPixel which return a reference to a pixel.  The
implementation calls the DataAccessor::Get() method which returns a pixel on the stack. Seems like
this will cause a problem. 

It looks like we need to be very careful about returning references to a pixel.  Does GetPixel() need
to return a pixel on the stack in order to properly support adapters?

Also, does this mean an iterator should NOT provide operator* ? Or not provide an lvalue version?
