I draw on an instance of BufferedImage and blit it to the screen in the
paintComponent() method. Now I am not sure how to react on a resize of the
output window. I can think of 3 strategies:

1. start with a BufferedImage the size of the whole screen and only use the
visible portion

2. resize the BufferedImage when needed

3. recreate the BufferedImage when needed

What strategy is best? I can always redo the painting since it is a 'View'
of the underlying 'Model'.
