java.lang.Objectcom.sun.electric.database.geometry.Orientation
public class Orientation
Class Orientation
represents 2D affine transform which is composition of rotation and possible flip.
The C code used an angle (in tenth-degrees) and a "transpose" factor
which would flip the object along the major diagonal after rotation.
The Java code uses the same angle (in tenth-degrees) but has two mirror
options: Mirror X and Mirror Y.
