Add throttled rendering in the render engine

[tonilastre]

Currently the issue happens if user runs orb.view.render() within the high volume event like OrbEventType.MOUSE_MOVE, e.g.

orb.events.on(OrbEventType.MOUSE_MOVE, (event) => {
  // Do something
  orb.view.render();
});

The render call by the user will affect the performance because it is an additional render call to the internal rendering. There should be a way to define FPS (frame per second) where the rendering engine would throttle rendering calls in order to satisfy defined FPS.

Fixed in release v0.1.3.
