Creates a new annotation to be displayed within the given area.

Parameters:

x - the x-coordinate for the area.

y - the y-coordinate for the area.

width - the width of the area.

height - the height of the area.

drawable - the drawable object (null not permitted).

 public Object clone() throws CloneNotSupportedException 
{
        return super.clone();
}

Returns a clone of the annotation.

Tests this annotation for equality with an arbitrary object.
