		Tabbed container.
	</brief_description>
	<description>
		Arranges [Control] children into a tabbed view, creating a tab for each one. The active tab's corresponding [Control] has its [code]visible[/code] property set to [code]true[/code], and all other children's to [code]false[/code].
		Ignores non-[Control] children.
		[b]Note:[/b] The drawing of the clickable tabs themselves is handled by this node. Adding [Tabs] as children is not needed.
