____________________________________________________

above is the code and i need to do some changes:

a) Add a third red button to the upper torso b) Give the snowman a mouth instead of of the line he has now (you will need to use the JavaFX Ellipse class to create the smile) c) Move the sun to the upper-right corner of the picture d) Display your name in the upper-left corner of the picture e) Shift the snowman 20 pixels to the right
