Use Resize Observer API for ScrollBar #44

Open kyoshino opened 8 years ago

We have removed the non-standard MozScrolledAreaChanged event in #39 to make the ScrollBar widget e10s-friendly. The current implementation using requestAnimationFrame is much better, but it eats memory. The Resize Observer API, that will be implemented in Firefox soon, is the final answer for this.

We perhaps don't need the new API. See CSS deep-dive: matrix3d() for a frame-perfect custom scrollbar for an interesting approach.
