Most of the current icons in gnome-themes can be downloaded in SVG format. Some of the newer stuff has been created by Suzanna Smith, but I believe it's only available as bitmaps. In that case that artwork needs to be manually traced (or auto-tracers' output touched up; I believe this would be more work than tracing it by hand).FIXME:wait for Sue's reply
Some of the artwork may not include a description as mentioned in Section , “Descriptions” of this document.
