Well, I'll tell ya.  The is no guarantee that XXor will give you
a color any different than the background.

We have tried many different variations, and this one has worked for
every workstation we have used :
	Evans & Sutherland ESV
	Stardent
	NCD X terminals
	Sparc Stations
	Solbournes
	386i's
	Tektronix
	SGI

	I am not sure if it worked with the DEC 3100 or not.
	I think it did.

The window managers twm and swm fail in drawing their lines to
the ESV.
