	<brief_description>
		An abstraction of a serialized scene.
	</brief_description>
	<description>
		A simplified interface to a scene file. Provides access to operations and checks that can be performed on the scene resource itself.
		Can be used to save a node to a file. When saving, the node as well as all the node it owns get saved (see [code]owner[/code] property on [Node]). Note that the node doesn't need to own itself.
		Example of saving a node:
		[codeblock]
		var scene = PackedScene.new()
		var result = scene.pack(child)
		if result == OK:
		    ResourceSaver.save("res://path/name.scn", scene) // or user://...
		[/codeblock]
