How Xfce works with svg files?

[Salvatore De Paolis]

Hi all
I'm trying to hack the xfce4-netload-plugins to allow showing a network icon
near the double progressbars.
Since xfce-panel seems to manage svg files, i though it would be as nicer if i
could work with them.
I get a look in the xfce4-panel and the Changelog state

* panel/icons.c: Added .svg support for themes. (librsvg provides a
  gdk-pixbuf loader), pointed out by keke at plskthx.org

but such icons.c file do not exists in the xfce4-panel tree.

Can anybody point me to the file where i can see an example of loading a svg
image?

Regards
S.
