After a spirited discussion, localOverlay is getting some children. * localOverlayBlockers - UI elements that are meant to prevent interaction with the element. This includes Phantoms and Highlights. *localOverlayControls - UI elements that are meant to be interacted with in order to modify the element. This includes resize handles and drag marker. *localOverlayMenus - UI elements that should always position above all other controls. This includes the context menu.
