**    huge output files.  The university prototype browser uses RLE
**    compression on the images, which causes them to print slowly,
**    but is a huge win on some class of images.
** +  12 bit files can be constructed which print on any printer, but
**    not 24 bit files.
** +  The 12 bit code is careful not to create a string-per-row, unless
**    it is going through the compatibility conversion routine.
** +  The 1-bit code is completely unused and untested.
** +  It should squish the image if squishing is currently in effect.
