a better solution is to junk xpr and translate the X window dump
into PostScript directly, using the PostScript "image" operator.  
PostScript images can be rendered in 1, 2, 4, or 8 bits, even on 
monochrome laserprinters (PostScript does the half-toning).

this program, (call it "xpsimage" or some such) would need to convert
from RGB to grayscale:

	i = (R * .30) + (G * .59) + (B * .11)

see the PostScript "Red Book" for info on the "image" operator, or give me
a call.

ps - if someone writes this utility, i'd like a copy.  i'd do it myself, but i
am way overcommited as it is.
