	<description>
		[GridContainer] arranges its child controls in a grid layout. The number of columns is specified by the [member columns] property, whereas the number of rows depends on how many are needed for the child controls. The number of rows and columns is preserved for every size of the container.
		[b]Note:[/b] [GridContainer] only works with child nodes inheriting from [Control]. It won't rearrange child nodes inheriting from [Node2D].
