textwidth and fontstrings

[Franz Danzi]

Dear Sirs,

I really enjoy working with your fine window manager. Thank you!
Please find the attached c file. This is a modified version of the
textwidth utility from the dzen2 package. If you use this in your
panel.sh this would allow you to define a more modern fontstring like so:
font="Sans:style=condensed:pixelsize=12:antialias=true:autohint=true"

Kind regards, Franz Danzi
