+equivalent example code for the lower-level joystick API.

+Please note that on the web, gamepads don't show up until you interact with
+them, so press a button to "connect" the controller.
+
+Also note that on the web, gamepad triggers are treated as buttons (either
+pressed or not) instead of axes (pressed 0 to 100 percent). This is a web
+issue, not an SDL limitation.
