If I understand this correctly all that should be required is a simple
rebuild of gdk-pixbuf in an environment which provides the suitable
libpng version, as gdk-pixbuf already depends on libpng-dev (| libpng12-dev).

An upload to experimental would have to temporarily change the dependency
to something like libpng-dev (>= 1.6) | libpng16-dev, since satisfying
from unstable is prefered over experimental but we explicitly want
the experimental version.

Once the transition goes live for real and libpng1.6 is uploaded to
unstable a binNMU of gdk-pixbuf should make it pick up the newer version
without any changes from the current state.

If my above understanding of only temporary changes needed is correct,
please do feel free to NMU to experimental.

If there are any changes you want preserved, please post a patch to
this bug report and I'll try to make sure it gets committed to
pkg-gnome svn. (You can also quickly reach people via #debian-gnome
on irc.debian.org.)

Thanks for your time working on the libpng transition.
