I think the icon was derived from `tango-icon-theme-0.8.90/scalable/status/network-wireless-encrypted.svg` in the [Tango Icon Theme Release](http://tango.freedesktop.org/releases/tango-icon-theme-0.8.90.tar.gz). If you look at the archive, you can see there are icons adapted to different pixel grid sizes, which is a manual artistic process that ensures the icon is crisp, not blurry at small sizes. Also I recommend having a look here: https://airwebreathe.org.uk/doku.php?id=wine_icons I created this site many years ago when I originally introduced Tango into Wine.
In Wine the [buildimage](https://gitlab.winehq.org/wine/wine/-/blob/master/tools/buildimage?ref_type=...) script uses special ids in the SVG to separate a single SVG file into images within the ICO file.
For example [control.svg line 1001](https://gitlab.winehq.org/wine/wine/-/blob/master/dlls/shell32/resources/con...) has `id="icon:16-4"` for an embedded 16x16 4-bit image.
