A widget that positions its child according to the child's baseline.
This widget shifts the child down such that the child's baseline (or the bottom of the child, if the child has no baseline) is baseline logical pixels below the top of this box, then sizes this box to contain the child. If baseline is less than the distance from the top of the child to the baseline of the child, then the child is top-aligned instead.
