Description of problem:
If signal strength percentage is displayed, the width of the wireless
applet changes when the number of digits in the percentage changes. 
In particular, if signal strength hits 100%, the applet pushes its
neighbors on the panel to the right, and when strength drops below
100%, the other applets shift left.  The movement is rather
disconcerting. 

Version-Release number of selected component (if applicable):
gnome-applets-2.4.1-1

How reproducible:
Always

Steps to Reproduce:
1. Install wireless applet and select "display signal strength" in
preferences.
2. Move applets on the right as close to the wireless applet as possible.
3. Sit close to a WAP and activate the wireless interface.
    

Actual Results:  Wireless applet changes width as signal strength
varies from 100% to nn%.  Other applets shift back and forth to
compensate.

Expected Results:  Applet should have constant width no matter how
many digits are displayed.
