2. Extend the program to make the sprite jump when the space key is pressed.
3. Extend the program to drag and drop the sprite using the mouse when left mouse button is down.
4. Write a program to make the GraphicsWindow behave like the TextWindow so you can emulate as  many of the TextWindow commands as possible, like WriteLine, Read etc.
