Thanks for the contribution!

Everything looks good, but I'm not quite sure I want to merge these into the base repo at this time, as I would like to keep the core system's method signature low.

In the future, I want to actually create a secondary library containing the more advanced implementations to be packaged as font-utils-views (or something along those lines, similar to how Google has split their play-services libraries) as to not include more than the developer needs to accomplish their tasks.

I'm going to leave this pull request open, though, and I'll merge these into that when I get the chance to split the library.
