Class AlignContext

public abstract class AlignContext extends Object

To position an element inside an box, we need the following data:

(1) Offset. The distance between the parent's top-edge and the child's top edge.

(2) Dominant baseline. The childs alignment point is defined by that one.

(3) Ascent. The distance from the baseline to the top edge.

(4) descent. The distance from the baseline to the bottom edge.
