description
Reads a
portable bitmap as input, and outputs a portable bitmap
enlarged N times. Enlargement is done by pixel replication,
with some additional smoothing of corners and edges.
notes
pbmpscale works best for enlargements of 2. Enlargements greater
than 2 should be done by as many enlargements of 2 as possible,
followed by an enlargement by the remaining factor.
