Out of curiosity, could you detail what that does?

[AdrieanKhisbe]

Travis new infrastructure is running on a container infrastructure.
Synce we need a C++ compiler, to build native module, we need to install it. (with the needed libraries for canvas)

Thanks for contributing!

Could you squash the commits into a single one, as the whole change is fairly small?

[AdrieanKhisbe]

about squashing, I don't recommend it. -> that helps identifying falling part of the CI build, and attach change to reason. (for future ci modification if needed)
But it's your call (confirm or not along with the other questions), and I'll do. 😃

about squashing, I don't recommend it

What I need commits to be are to help me when I inevitably have to do some archaeological exploration or bisect. Having a single PR (which should correspond to solving a single issue) include multiple commits involved in solving the same piece of the puzzle makes it difficult to see how they relate. Typically, here, AdrieanKhisbeArchives@c8e083b and AdrieanKhisbeArchives@d3e06b3. I could go through the work of explaining exactly which commits should be squashed together, but it would take a long time. For a PR this simple, a single commit is really not an issue.

Every commit should make the build pass. Otherwise, git bisect won't work.

Thanks to this, and the context from the discussion, most of these changes have been merged. Containers were added in #768. PRs are flowing, so please free to open a new PR if there are additional bits worth adding. Closing.
