Class Overview
An Anchor represents a point inside or on a bounding rectangle that
is used to position a shape relative to another shape.
Pre-existing anchors are provided for the nine common anchor points that
most people will want to use: TOP_LEFT, TOP,
TOP_RIGHT; LEFT, CENTER, RIGHT;
and BOTTOM_LEFT, BOTTOM, BOTTOM_RIGHT.
Since Anchor is an abstract class, users can easily implement their
own custom anchors for different types of shapes. For example, a circle
might provide anchors that lie on the curve itself rather than on its
bounding box.
