A Layer is an abstract class representing a visual element of a game. Each Layer has position (in terms of the upper-left corner of its visual bounds), width, height, and can be made visible or invisible. Layer subclasses must implement a <A HREF="../../../../javax/microedition/lcdui/game/Layer.html#paint(javax.microedition.lcdui.Graphics)"><CODE>paint(Graphics)</CODE></A> method so that they can be rendered. <p> The Layer's (x,y) position is always interpreted relative to the coordinate system of the Graphics object that is passed to the Layer's paint() method. This coordinate system is referred to as the <em>painter's</em> coordinate system. The initial location of a Layer is (0,0). <p>
