I modified our version of xps to display color.  Our X11.c is not the one that
comes with X11 R4, however.  It has evolved here independently over the past
few years (it has comments about changes made for X11 R2 which don't appear in
other versions, so it is at least 2 years old).  I consider my work incomplete:
it assumes 2^8 colors, and a side effect of my changes was to turn off
interpolation of colors with dot patterns (so this doesn't work well on
monochrome).  I can send diffs to anyone interested.
