Disagreed. Perhaps you're confusing blur with mosaic here? Mosaic does
wonders with nearest neighbor, if you scale down by an integer factor
and use the same number for the mosaic size. Thus you get the exact
same result as +a0.0 +rn, where n is the scale factor.

Gaussian blur helps a lot in most other downsampling algorithms, with
the slight drawback that some careful work with unsharp mask is need
after the resizing to bring out the (now) subpixel details.
