PNG is important.  If we want Emacs to change icons when the Gnome/Gtk+ theme 
changes, Emacs will then use PNG icons.  Most (all?) Gnome/Gtk+ icons are in 
PNG format.  But this is code that Gtk+ loads dynamically with dlopen, so 
Emacs itself does not know that PNG is used.  Not sure if that affects the 
license issue?
