getCenter

public Point getCenter()

Description copied from interface: Shape

Get the geometric center of the shape. The center of a shape can be interpreted in many ways (center of mass, circumcenter, inscribed center etc.). No strict requirement is given here, but typically the circumcenter should be supplied. This method is most prominently used to find the average center-position of a collection of shapes such that scene-viewers can be centered on the scene.
