   Using the  { < . . . > } sequence to get sampled image data
   onto the stack as the procedure argument to the  image
   operator.  This only works up to a certain point, and then
   breaks, resulting in plenty of debugging time on the part
   of the consumer, not the developer.  Use the
   readhexstring  operator and do it right next time, please.

Yes, if you're going to use {< . . . >}, you may as well use
readhexstring.  However, if you need multiple copies of the image, you
pretty much *have* to use /image < . . . > def and then {image}.
Otherwise you have to put multiple copies of the image in the input
stream.  At 9600 baud, I'd rather not.
