Add example of Vector vs Raster Graphics

On the first day, the skeleton encountered a fox

"That fox will make a good example of Vector vs Raster Graphics" thought the skeleton
Suddenly, Captain Obvious appeared to challenge the skeleton to a battle!

"THAT FOX IS SUPERFLOUS" shouted Captain Obvious.
"But pretty pictures!" cried the Skeleton.
Captain Obvious hesitated, clearly torn. After a long pause, he sighed.
"I guess you've got me there" he said.

(NB: I will probably remove this example when I have something of value to put in its place)
