Fonts for use by capture browser

[rebeccacremona]

@jcushman did some work on this, as we experimented with using Chrome for capture. Let's not lose that work; let's do some more work, and, once we are using Chrome, merge it in.

August 29 2017 discussion:

While trying to get capture via Chrome working in our Vagrant box (which is how we did things before we switched to Docker), Jack was debugging problems and found https://bugs.chromium.org/p/chromium/issues/detail?id=695212#c18. It suggests installing gnu-free-sans-font. Jack says he's not sure of the debian equivalent. Ben says, "libosmesa6-dev? fonts-freefont-otf or fonts-freefont-ttf?"

Jack:

I took a look at font rendering -- here's http://www.cssfontstack.com/ with Chrome on my local dev (with fonts-freefont-otf installed):

so if we cared about font rendering in screenshots, that would be a thing to work on

Did code result? The above says we should "merge it in." If yes, I don't see any relevant branches (only the earlier https://github.com/jcushman/perma/tree/chrome-support). I think probably there is no code to consult.

We were helped out by https://github.com/harvard-lil/perma/commit/c104e989f53a5b548253d50e638c50defde94b78, and are still installing those two font packages today

Evidently, we are not installing fonts-freefont-otf, the one that Jack mentioned.

Let's just install that and not think about it! Though I wonder if there are other fonts we should install too. I don't know really how a person would find out.

To be investigated for Scoop deployment.
