Hoping to make some useful outcome to this thread ...

This is incorrect. I suggest the following.

Once 2.4 is out and there is a review of the interp naming strategy w.r.t.  
downscaling the use of NONE should be probably be changed as well. (A  
scaled up image with no interpolation has holes in it.)

  Even though rather simplistic, N.N _is_ interpolation.
