I would think that this would also be a nice means of harmonizing the
handling of gtk+ stock icons with replacement/themed icon sets, since at
the moment the stock icons are compiled into a header file, and
replacements via RC-file theming must be provided as separate image
files.  IMHO neither of these cases is ideal, providing a common format
for multi-images, which could be used by gtk_icon_factory instances as
well, would seem more flexible and efficient.  It appears to me that at
present there are two icon sets in memory whenever the default set is
overridden, since we can't unload the hard-coded ones.
