[Evolution] Does Evolution support theme/skins?

[Harry Lu <harry lu sun com>]

Hi! Does Evolution support theme/skins?
I know that Evolution can use the theme specified by Gnome Control 
Center's Theme Selector, but this is basicaly about the GTK widget.  I 
want to know if Evolution support changing the icons, e.g  the Inbox 
icon, the Reply icno, etc?
I saw a directory named "art" under the root directory of Evolution 
source, and there are many .png files.  For a installed evolution under 
RedHat 8.0,  those .png files are installed under 
/usr/share/images/evolution.  So I think change this files can change 
Evolution's icons, right? But it would be great that Evolution can 
support multiple group of icons.
Thanks!
