This class performs the real work of vertically positioning inline boxes within a line (i.e. implementing the vertical-align property). Because of the requirements of vertical-align: top/bottom, a VerticalAlignContext is actually a tree of VerticalAlignContext objects which all must be taken into consideration when aligning content.
