+ * This extension of the <tt>java.awt.Graphics2D</tt> abstract class
+ * is still abstract, but it implements a lot of the <tt>Graphics2D</tt>
+ * method in a way that concrete implementations can reuse.
+ *
+ * This class uses a <tt>GraphicContext</tt> to store the state of
+ * its various attributes that control the rendering, such as the
+ * current <tt>Font</tt>, <tt>Paint</tt> or clip.
+ *
+ * Concrete implementations can focus on implementing the rendering
+ * methods, such as <tt>drawShape</tt>. As a convenience, rendering
+ * methods that can be expressed with other rendering methods (e.g.,
+ * <tt>drawRect</tt> can be expressed as <tt>draw(new Rectangle(..))</tt>),
+ * are implemented by <tt>AbstractGraphics2D</tt>
