lottie-render-bevy

Using Bevy as the engine to render Lottie files.

Bevy is chosen as a renderer because:

• It is relatively mature, has an active community and clean design
• Allows interacting with entities as a game engine, this enables future interactive Lottie file editing apps
• Supports both 2D and 3D
• Supports lyon, which is a good choice for vectorized graphics rendering on GPU

Known limitation

Audio looping

Due to https://github.com/RustAudio/rodio/issues/176 , Bevy do not support audio seeking, so audio playback when looping animation in this renderer is bugged.

We may try to directly use Symphonia to play audio in the future.
