Doubtful. :)

It would be, but a few things:

(1) is it possible to cram unlimited extra info into a PNG?
    (particularly the label text/position/color/size/etc. data)

(2) other than being a little bit of effort to keep track of
    inside Tux Paint's codebase, who is this bothering?
    (that's a serious question ... in terms of sharing an image to
    your relatives, for example, you just sent them the 'main' PNG;
    do people really share (individual) images across installations
    of Tux Paint?)

Would bundling it all together (either into our own Tux Paint file
format *shudder* or something like a ZIP (like Java JARs or EPUB ebooks))
be more suitable?

Keep in mind we'd want to keep backwards-compatibility, so we'd at least
need to know how to load all of that data, even if we no longer saved
new files out that way.  (And due to that, I feel like it's not worth
the effort.)
