Pong: Switch to global tracking

Browse source 
When I play Pong, I don't really pay attention to whether my mouse is in
the Pong window. That means that sometimes, annoyingly, the window loses
my mouse, and I lose control of the paddle. Gasp! D:

This commit teaches Pong the wonders of global mouse tracking, thus
enabling the player to focus solely on the game.
