Returns the duration of the animation path, in seconds. The duration is dependent on the control point times, loop mode, and constant speed setting.

The duration is typically the time between the first and last control points, but can be affected by the following factors:

• When moving at a constant speed, the duration will depend on the total distance between control points and the constant velocity setting.

• When the loop mode is set to viz.CIRCULAR, the time between the last and first control point will be added to the duration.

The duration is NOT affected by the path speed factor (<animationpath>.setSpeed).
