/cc @jfirebaugh @kkaefer would love some assistance on this patch so that it doesn't get merge-pwned by changes in the master branch. This is needed to close https://github.com/mapbox/mapbox-gl-online/issues/1300 in gl-online and has completed twin issues in gl-style-spec and gl-js: I'm trying to implement style v8 compatibility and have a goal of:

• for the text-font property, it should now be an array of strings instead of a comma-separated string
• the least invasive way to implement this would be to comma-join the array as soon as it enters gl-native
• but the template approach means that we'll have to do some sort of templating magic to make this flow different than other arrays

@tmcw looks like you figured it out? The only thing missing is changing the style fixtures since the style format changed.

[tmcw]

Yep, forgot to post back here - sorry. The text-font issue is now fixed, but we then came to the agreement that we should go whole-hog and implement types too, which I'll do first in style-spec.

In the interest of shipping v8 sooner rather than later, does anyone @mapbox/gl want to adopt this side of the (spec, js, api, native) taskcombo?
