No polished screenruler on linux?

One disabling problem with each promising project:

kruler - bug in vertical mode - counts the window decoration as part of the length in pixels, not cool. bug report

screenruler - version in ubuntu repos still doesn't show a tooltip with the measurement, you have to count the little black lines (!). Supposedly a tooltip has been added, but no one has bothered to package it apparently. Have checked debian sid, ubuntu karmic and jaunty.
