easeInSine breaks path animation

Hey, While working on some sample animations using anime I discovered a weird bug. When I use easeInSine as easing, it breaks path animation. If I change it to anything else, everything works correctly.

Here is the codepen that shows this bug http://codepen.io/hinok/full/ObdaRp/

I’m using anime 1.1.2.

Edit

I’ve found another equation for easeInSine like below

easeInSine: (t) => {
  return 1 + Math.sin(Math.PI / 2 * t - Math.PI / 2);
},

If I override anime.easings, animation looks correctly.

const tryToFixEasing = {
  /* @source https://gist.github.com/gre/1650294#gistcomment-1924831 */
  easeInSine: (t) => {
    return 1 + Math.sin(Math.PI / 2 * t - Math.PI / 2);
  },
};

anime.easings.easeInSine = tryToFixEasing.easeInSine;

So it seems that there is a problem with easing equation.

@juliangarnier btw could you unveil when do you plan to release v2 😃?
