Btw, there could be a way to speed up equal_lists, I think.  It
compares image specs, not just any 2 lists, right?  An image spec
always starts with the symbol 'image'.  So it should be enough to
compare only the list members starting from the second one.  The image
specs of the tool-bar buttons have 9 members, so this might yield an
11% speedup.
