Improve joystick visualisation in gamepad example

The joystick range is a float from -1 through +1. Casting this to int
yields only three possible values: -1, 0, and 1. This gives a
misleading joystick placement in the demo.

By casting to int after the multiplication, the demo reveals the
analog feel of the joystick.
