I'm glad to hear that giflib has an active maintainer now.  Replacing
libungif with a maintained module makes a lot of sense.  However,
looking at my distribution, it doesn't look like a whole lot of software
actually uses this library.  This is a pity, as it's better to have just
one image loader available instead of multiple, especially when the
inevitable security errata happens.

When we did the gif loaders for gdk-pixbuf, we looked at using libungif.
However, it didn't support two vital features -- incremental loading and
sane threading support.  I imagine that we could switch away from our
current code to libgif if those features appeared.  Are you doing new
development on it?  Is this in your roadmap at all?

Thanks,
-Jonathan
