** This function works, but is starting to show it's age, as the list
** of known problems grows:
**
** + The images are completely uncompressed, which tends to generate
** 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.
