	<brief_description>
		Placeholder for the root [Node] of a [PackedScene].
	</brief_description>
	<description>
		Turning on the option [b]Load As Placeholder[/b] for an instantiated scene in the editor causes it to be replaced by an [InstancePlaceholder] when running the game, this will not replace the node in the editor. This makes it possible to delay actually loading the scene until calling [method create_instance]. This is useful to avoid loading large scenes all at once by loading parts of it selectively.
		The [InstancePlaceholder] does not have a transform. This causes any child nodes to be positioned relatively to the [Viewport] from point (0,0), rather than their parent as displayed in the editor. Replacing the placeholder with a scene with a transform will transform children relatively to their parent again.

			<description>
				Call this method to actually load in the node. The created node will be placed as a sibling [i]above[/i] the [InstancePlaceholder] in the scene tree. The [Node]'s reference is also returned for convenience.
				[b]Note:[/b] [method create_instance] is not thread-safe. Use [method Object.call_deferred] if calling from a thread.

		<method name="get_instance_path" qualifiers="const">
			<return type="String" />
			<description>
				Gets the path to the [PackedScene] resource file that is loaded by default when calling [method create_instance]. Not thread-safe. Use [method Object.call_deferred] if calling from a thread.

		<method name="get_stored_values">
			<return type="Dictionary" />
			<param index="0" name="with_order" type="bool" default="false" />
			<description>
				Returns the list of properties that will be applied to the node when [method create_instance] is called.
				If [param with_order] is [code]true[/code], a key named [code].order[/code] (note the leading period) is added to the dictionary. This [code].order[/code] key is an [Array] of [String] property names specifying the order in which properties will be applied (with index 0 being the first).
