i3 - improved tiling WM

i3bar: Fix "off by one"-error when rendering workspace buttons in i3bar

Patch status: rejected

Patch by Øystein Dale

Long description:

The height of the buttons were depending on the font height rather than the
height of the bar itself, leaving room for a 1px gap between the border
of the button and the bottom edge of the bar.
