Well for clarity and consistency reasons I prefer if dmenu cleans up
all resources acquired at the end. So that cleanup() was removes looks
more like a bug to me and thanks to Dan for pointing this out.

As for the XFT bits I will have a look how to integrate them probably
as a different draw.c altogether. I need to analyse the impact. There
were plans to also have a cairo based draw.c probably at some point
(also shared with dwm).
