Flexible sizing

[dlewand691]

Wondering what your thoughts are on adding flexible sizing instead of strict breaks. Here's some examples:

Hi @dlewand691,

I'd love to add it. I considered it when developing the project, but Safari (and other WebKit-based browsers) didn't support any method of calculating new text sizes without a hard break point. As a result, I opted for text sizing via hard break points because it worked everywhere.

I haven't checked Safari's compatibility with dynamic text sizing since then. If the necessary support has been added, it would be a nice enhancement. PRs are also welcome if you're up for it!
