Skottie - Lottie Animation Player
================

Skia now offers a performant, secure native player for JSON animations derived
from the Bodymovin plugin for After Effects. It can be used on any platform
where you are using Skia, including Android & iOS.

The player aims to build upon the Lottie player widely used for animations
today, improving on the performance, feature set, and platform cohesiveness for
our clients. We are big fans of the Bodymovin format and where possible,
contributing advancements back to Bodymovin/Lottie.
