		Joint used with [Skeleton2D] to control and animate other nodes.
	</brief_description>
	<description>
		Use a hierarchy of [code]Bone2D[/code] bound to a [Skeleton2D] to control, and animate other [Node2D] nodes.
		You can use [code]Bone2D[/code] and [code]Skeleton2D[/code] nodes to animate 2D meshes created with the Polygon 2D UV editor.
		Each bone has a [member rest] transform that you can reset to with [method apply_rest]. These rest poses are relative to the bone's parent.
		If in the editor, you can set the rest pose of an entire skeleton using a menu option, from the code, you need to iterate over the bones to set their individual rest poses.
