		Skeleton for characters and animated objects.
	</brief_description>
	<description>
		Skeleton3D provides a hierarchical interface for managing bones, including pose, rest and animation (see [Animation]). It can also use ragdoll physics.
		The overall transform of a bone with respect to the skeleton is determined by the following hierarchical order: rest pose, custom pose and pose.
		Note that "global pose" below refers to the overall transform of the bone with respect to skeleton, so it not the actual global/world transform of the bone.
