* Changed the patch to apply with Pidgin
* DATE: 15th May 2007

This patch is based on Gaim 2.0.0 Beta6 patch:
===============================================
http://www.linuxpowertop.org/patches/gaim-2.0.patch

Author: Arjan van de Ven <arjan@linux.intel.com>

* Make GAIM remember that X has the screensaver extension when it does; this avoids
  keeping X alive all the time because it's being asked stuff
* Make the 5 second "Am I idle for 10 minutes" timer only fire at the time points
  that are interesting, so after 10 minutes or any other configured time; and not
  every 5 seconds. This code also would keep X active every 5 seconds which prevents
  X from going into idle mode.
