I took a stab at adding SVG icons, as found in the GNOME Adwaita Icon
Theme.  I had to scrub some color details from the SVG files by hand,
but they now seem to automagically adapt to the :foreground and
:background of the current face (but I could be wrong about that as I
don't understand how this is supposed to work).

How would a patch like the attached relate to the changes you propose,
