Yes, I did remember.  Like GS, "links" also uses libjpeg, which has
value in itself.  GD, libTIFF and GeoTiff all also contribute to a
graphics workbench and all are actually quite open to being converted
to native Plan 9.

That is where I'm hoping to go, but I have some immediate objectives
that have slightly higher priority, as mentioned.  In the process,
I've had to make adjustments to the APE headers and to my view of the
Plan 9 directory hierarchy that I hope will benefit others as well.

In the medium term, I think there'd be advantages to extracting zlib,
libpng and libjpeg (at least) from GS, "links" and possibly other
places and accept them as first class citizens in the Plan 9 system.
