You might want to ask Jeff (jeff@abisource.com) about any conversions to
Windows formats. I believe he's implemented a converter so that XPMs are
rendered into bitmaps at run-time on Windows, allowing us to use XPMs for
toolbars for both platforms. Now, for icons and cursors, that's another
set of requirements. :)
If you want a set of the icons, you can use CVS to checkout just the
abi/src/wp/ap/xp/ToolbarIcons directory, it's full of X Pixmap files
(basically C headers in ASCII with a color map at the top) you should
be able to convert to whatever format is neccessary. If you'd like
access to an even broader spectrum of icons (the set from which we
chose our own), visit http://tigert.gimp.org/gnome/gnome-stock/ or
some of its parent directories. These icons are part of the GNOME
project, and are probably GPLed.
