// JoystickPos queries the current position of one or more axes of a joystick.
// The positional values are returned in an array, where the first element
// represents the first axis of the joystick (normally the X axis). Each
// position is in the range -1.0 to 1.0. Where applicable, the positive
// direction of an axis is right, forward or up, and the negative direction is
// left, back or down.
//
// Note: If len(axes) exceeds the number of axes supported by the joystick, or if
// the joystick is not available, the unused elements in the pos array will be
// set to 0.0 (zero).
//
// Note: The function returns the number of actually returned axes. This is
// the minimum of len(axes) and the number of axes supported by the joystick.
// If the joystick is not supported or connected, the function will return 0 (zero).
