I'll look into that as I am doing the BW conversion, see below.

I batch converted them with netpbm.  But using Gimp gives better 
results,
I'll reconvert the PBMs and check them in shortly.

They are from GTK, don't know who did them.  According to RMS they are 
OK,
he said previously:
  "We can use the GMOME icons on the same basis that we use things
such as oldxlib: saying that they are not part of Emacs, but
used by Emacs and distributed with Emacs."

Exactly where we shall say this I don't know.  Is an entry in NEWS 
enough?
