--- Comment #9 from Michael Catanzaro <mcatanzaro at igalia.com> ---
The intent behind the policy (at least, my intent) is to not introduce dependencies that are too new for our target distros. Adding a new dependency that already exists in both target distros (Ubuntu 14.04, Debian Jessie), which will not cause any build problems, seems fine to me.

Ubuntu 14.04 has libepoxy 1.1, so we can add a dependency on that. If we want to add a dependency on libepoxy 1.2, then we'd need to wait until next April, when our target switches from Ubuntu 14.04 to Ubuntu 16.04.

And, in particular, what other ports? If it's just EFL, they target Ubuntu; I strongly suspect they would be happy to use system libepoxy. If it would be needed for any Apple ports, then it needs to be bundled. I'm not sure about WinCairo.
