description: "Interface holding the size and alignment lines of the measured layout, as well as the children
positioning logic. [placeChildren] is the function used for positioning children.
[Placeable.placeAt] should be called on children inside [placeChildren]. The alignment lines can
be used by the parent layouts to decide layout, and can be queried using the [Placeable.get]
operator. Note that alignment lines will be inherited by parent layouts, such that indirect
parents will be able to query them as well."
