Example 1 demonstrates:
Changing object textures in reaction to input movement (left/right).
Example 2 demonstrates: Drawing of background with random choices of texture,
creating pseudo random animation, and detecting collision of objects.
Example 3 demonstrates: working with current position. Notice that, unlike a mouse,
gamepad is an input device that does not have a default on-screen icon representing a current position.
This example shows one way of conveying the sense of current position for the user.
