Incomplete answer.  Colors should be set up with X calls too in place
of pixwin calls.
In XView the color-map-segment code finds a contigious block of free
color space and puts the color table there.  The pw_rop command calls
XPutImage, but adds the color table offset to each pixel in the XImage
data before XPutImage and subtracts it after.
