Owen, Thanks for the advice.
Will and I have discussed crosshairs since I posted this "XOR" question. He felt that transparency alone was fine for a first pass. Transparency is much simpler in Clutter.
Nonetheless, I will keep your pointers in mind for future development of this feature, and, possibly, other colour manipulations.
Thanks again. -- ;;;;joseph 'Clown control to Mao Tse Tung.' - D. Bowie (misheard lyric) - _______________________________________________ gnome-shell-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gnome-shell-list
