/**
 * An applet the draws a frog.  Sort of.  OK, it draws something that
 * looks like a frog in that it is green and has bulging eyes.  You want
 * good drawings, go to the fine arts department.
 *
 * This is an example of using the <CODE>Graphics</CODE> class to
 * draw things using <CODE>setColor</CODE>, <CODE>drawString</CODE>,
 * <CODE>drawLine</CODE>, <CODE>fillRect</CODE>, <CODE>drawOval</CODE>,
 * and especially <CODE>fillOval</CODE>.  Oh, yes, lots and lots of
 * <CODE>fillOval</CODE>.
