Certainly more elegant than steganography, and I think we discussed this
earlier on irc, but I think the objections raised at that time were
twofold: lack of support for it in SDL (not a showstopper, because it
can be managed by direct calls through the libpng api?) and the text
info would be rewritten by any other app that rewrites the file (same
issue as with steganography, and same reply: who cares? we don't have
to support preserving this info if some other app edits the image).
