Enclosing class:

SyntaxGraph

public class SyntaxGraph.Layouter
extends SinglePhase

Every action method returns a SizeInfo object in the register sizeInfo. Each graph has one y-value as its entry and exit height, and an entry and exit x-pos. These are stored in SyntaxGraph.y, SyntaxGraph.inX and SyntaxGraph.outX and are all RELATIVE to the containing graph.
The action method for a combinator shifts the SizeInfo areas relative to its origin (0,0), and stores the resulting co-ordinates.
Later in the drawing process. these shifts are respected by concatenating affine transformations.
The y-coordinate grows downward. The code for "opt" is commented to illustrate this strategy.
