	<brief_description>
		A node for inverse kinematics which may modify more than one bone.
	</brief_description>
	<description>
		Base class of [SkeletonModifier3D]s that has some joint lists and applies inverse kinematics. This class has some structs, enums, and helper methods which are useful to solve inverse kinematics.

			If [code]true[/code], the solver retrieves the bone axis from the bone pose every frame.
			If [code]false[/code], the solver retrieves the bone axis from the bone rest and caches it, which increases performance slightly, but position changes in the bone pose made before processing this [IKModifier3D] are ignored.
