		A node for driving hand meshes from [XRHandTracker] data.
	</brief_description>
	<description>
		This node uses hand tracking data from an [XRHandTracker] to pose the skeleton of a hand mesh.
		Positioning of hands is performed by creating an [XRNode3D] ancestor of the hand mesh driven by the same [XRHandTracker].
		The hand tracking position-data is scaled by [member Skeleton3D.motion_scale] when applied to the skeleton, which can be used to adjust the tracked hand to match the scale of the hand model.
