Desktop agnostic icon themes?

[Orion Poplawski <orion cora nwra com>]

I package gv, a Xaw3d based postscript viewer.  In currently I ship a 
.desktop file that uses the following icon:

Icon=postscript-viewer.png

which is apparently part of gnome-themes.  I actually use KDE, and with 
F9 KDE is no longer displaying the icon for gv even though gnome-themes 
is installed.  Now this may very well be a bug in KDE, but I'm also 
wondering if there is a desktop agnostic set of icons that could be used 
for programs like this?

I also just now found that gv does have a xbm icon in the package that I 
might be able to use.  Any pointers?

Thanks!
