formatNode
public boolean formatNode(int width,

Context cx)
- Description copied from class:
INode
- Children report dimensions (width and height), parent places at (x,y).
Bbox = union of children's bboxes
Children stacked vertically like TeX vbox; override to implement other layout strategies
To implement a new layout manager, override this method.
