That's more or less what I would have done if deb-multimedia.org wasn't
cooperating. I had a MR open for gegl to make its .symbols file generate
dependencies like "libgegl-0.4-0 (>= #MINVER#), libgegl-0.4-0 (<< 1:0)",
which would have meant the dependent packages wouldn't even need to add
Breaks - any rebuild would have been enough.
However, the correct resolution of that uninstallability is not
immediately obvious: it could be resolved by either "downgrading"
(really upgrading!) babl and gegl, or holding back the dependent
packages. We want the former, and the latter would be harmful.
Since deb-multimedia.org has cooperated with us on this, I think it's
better if we add the epoch and have the upgrade work with no special
action taken.
