Color::Xor uses xor'ing as the blending operation--the destination
will be xor'd with the source.  Doc uses this for highlighting

As for externals, there is only the manual page.  For internals, there is a paper
that will appear in this year's OOPSLA conference.  I'll make a copy of
the PostScript ftp-able as oopsla92.ps.Z soon (can't get to my ftp machine
right now).
