After development was stopped on oroborus, and before the website went away, there were some patches made available, one of which fixed a possible divide by zero error, and some feature enhancements. i don't have the Xft patch, but i have a patch containing the fix for the divide by zero issue, and 2 small feature enhancements: snap to window, and raise on click. have been running since oroborus development was stopped with no issues.
Created attachment 1338 [details, diff] patch to oroborus 2.0.4 to add some small enhancements and a bug-fix possible divide by zero, snap_to_window, and click_to_raise
http://www.dreamind.de/oroborus.shtml The project has been resurrected, apparently :)
I'm an enlightenment user, I should have never initially committed this ebuild, but I was trying it and thought someone else might like to.
These patches have been integrated by the new oroborus developer into his source tree.
