Skeleton2D parents a hierarchy of [Bone2D] objects. It is a requirement of [Bone2D]. Skeleton2D holds a reference to the rest pose of its children and acts as a single point of access to its bones.
+ To setup different types of inverse kinematics for the given Skeleton2D, a [SkeletonModificationStack2D] should be created. They can be applied by creating the desired number of modifications, which can be done by increasing [member SkeletonModificationStack2D.modification_count].
