/**
* @defgroup Lottie_Animation Lottie_Animation
*
* Lottie Animation is a modern style vector based animation design. Its animation
* resource(within json format) could be generated by Adobe After Effect using
* bodymovin plugin. You can find a good examples in Lottie Community which
* shares many free resources(see: www.lottiefiles.com).
*
* This Lottie_Animation is a common engine to manipulate, control Lottie
* Animation from the Lottie resource - json file. It provides a scene-graph
* node tree per frames by user demand as well as rasterized frame images.
