xftwidth: calculates pixel width of a string using a given Xft font

When you want to right-align stuff in dzen2 it's pretty painful.

I got fed up with dzen's textwidth that doesn't really work with modern fonts. I wrote a (pretty crappy) C program to do the same job but with Xft support.
Needs Xft and fontconfig of course

https://github.com/vixus0/xftwidth

Now you can just:

#!/usr/bin/bash

left="some text"
right="more text"
width=`xftwidth font:size=9 "${right}"`
echo "${left}^p(_RIGHT)^p(-$width)${right}" | dzen2

I like to always free a malloc'd pointer.
