CInitializer	A class that enables initialization and termination of the TVG engines
CAnimation	Enables manipulation of animatable images
CSaver	A class for exporting a paint object into a specified file, from which to recover the paint data later
CAccessor	The Accessor is a utility class to debug the Scene structure by traversing the scene-tree
CLottieAnimation	Enables control of advanced Lottie features
