A Coordinate is operationally like a shape but it can only be drawn as a dot or a cross and it only supports CenterAnchor.

Coordinates support affine transformations, however transfomations only displace a coordinate's origin they do not change how it is drawn (one cannot elongate the drawing of a coordinate with a scale). This is why coordinates are not Shapes, though one major use of coordinates is to illustrate anchor points on Shapes.

Note - the x is drawn regardless of any scaling or rotation.
