You need to negate the Z fields of the "camera_arg". camera.refz will also 
need to be negated:

camera_arg  camera = {
    0.0, 0.0, 0.0,                      /* reference position */
    1.0, 1.0, -1.0,                     /* camera position */
    0.0, 0.0, -1.0,                     /* up vector */
    60.0,                               /* field of view */
    -1.0, 1.0,                          /* front & back */
    CAM_PARALLEL                        /* projection */
};
