-/**
- * Implements the Square Dance game.
- * This simple game allows the user to move a black square around
- * the screen, and change the square's size during the movement.
- * When the game starts, a square of 30 by 30 pixels is shown at the
- * top-left corner of the screen. The user controls the square as follows.
- * The 4 arrow keys are used to move the square up, down, left, and right.
- * The 'z' and 'x' keys are used, respectively, to decrement and increment
- * the square's size. The 'q' key is used to quit the game.
