No, the effect Stefan points out has nothing todo with X* sucks
;)

It is because wmii draws 1px borders (hence the + 4), but dmenu
(like dwm) has dropped those 1px borders around labels, hence
they use font.ascent + font.descent + 2 as bar height.

But due to my understanding of your roadmap, you want to do the
rendering similiar to dwm, to provide more available screen
space to client areas.
