- Change the font used.
- Use the `:thin' border style to hide windows behind certain other
windows. For example: When using Emacs and conkeror, if conkeror is
placed behind emacs and the border is `:tight' I will see a tiny
portion of the conkeror window on my screen (due to emacs' size
hints). On the other hand if I use `:thick', it will use the border
color to fill it up, with `:thin' it uses the unfocus-color.
