Actually, the new libpng/libjpeg was in [testing] for a couple of
weeks while rebuilds were done for every single application in the
official repos (including [community] and [community-testing]). They
were all moved to [core],[extra], and [community] at the same time.

So no, it is not impossible, though very difficult. The devs/TUs have done it.

This would be a bug. I'm pretty sure the most recent versions for all
work though, unless your mirror is only partially updated. Haven't had
any problems here (though I don't use those specific apps).
