working on ability to have actual images inside of piglet primitives.
Initially I'm just reading in pnm images, however I can always use
netpbm(1) scripts to convert just about anything else into a pnm image
for me by writing a script...  This first directory has a simple program
to scale an image reading from stdin and writing to stdout.  It also has
a simple program that shows how to get an Xlib image map working.  The
idea is to be able to draw a rectangle, assign an image file to it, and
then have that rectangle display that image scaled to fit.  Then, I'd
like to make such an image a "background" with the BACk command and then
be able to trace photos to trace machine paths (like where to engrave a
mandolin to add a purfling or some such).
