Revert "When using nearest neighbor interpolation and not actually scaling, just copy the data.  (Note we don't do this for other kinds of interpolation, because the filtering on those interpolations could have an effect even when not actually scaling.)"

This reverts commit 1c9f9b5f6cb3b308df95e56f7230d71963837812.
