#12664: Animated Smileys make CPU usage going mad

--------------------------+-------------------------------------------------
 I use pidgin on Windows (32bit Version 2.7.3 on Windows 7 64bit).
 I am using the original Smilies Theme from here:
 http://wiki.andreineculau.com/Original_Smileys_Theme_for_Pidgin

 If I have this Smilies enabled and use some of them in an ICQ-
 Conversation, CPU Usage of pidgin.exe is between 20% and 25% (on a
 quadcore, so it is fully using one CPU).
 Additionally, the smilie animations are played way to fast! If I take a
 look at the gif-files using e.g. IrfanView, they play in normal speed.

 I have no plugins installed in Pidgin, it is a fresh install with just the
 smilies added.

 The CPU usage seems to be higher if the smilies are in the text fild where
 I enter the message.

 Here are two snapshots of the stack:
