Algorithm:
Scale image up.
Resynthesize with:
corpus = original size image
in map = original size image but scaled up and down to blur
out map = scaled up image
This restores the detail that scaling up looses.
It maintains the aspect ratio of all image features.
Unlike the original smart-enlarge.scm, this alters the original image.
