Scaled position of the joystick
or a 3D navigation device in vertical
and horizontal direction. The startup
position is zero.

The _force vectors (joy_force, key_force, mouse_force) have a limited range and a large 'dead zone', and are mostly used for keyboard-like movement. For the full analog joystick range, use joy_raw.
- If no joystick is found,
but a 3D navigation device by 3Dconnexion is
detected, the engine gives the startup message "3D
navigation device found" and
binds it in as a joystick device. In this case joy_force.x is controlled
by rolling or spinning the device, and joy_force.y by tilting. Development
