I'm not entirely sure what the origin of that distinction is, but my
understanding (mostly from reading Tab's comments/responses on the Blink
intent-to-implement thread) is that Nearest-Neighbor Scaling really
doesn't look "pixelated" at all when scaling down, so authors asking for
a "pixelated" look really don't want nearest-neighbor downscaling.  The
default scaling algorithm will do a better job of downscaling your image
in a non-datalossy-way than nearest-neighbor would.
