Jerky playback on Safari (iOS) using autoScrolling:false + dragAndMove:true

When I scroll slowly on iOS (iPhone), the playback is jerky.

Here's my simple code:

```

$(document).ready(function() {
var myFullpage = new fullpage('#fullpage', {
licenseKey: '-',
verticalCentered: true,
slidesNavigation: true,
scrollHorizontally: true,
scrollHorizontallyKey: "-",
dragAndMove: true,
dragAndMoveKey: '-',
responsiveSlides: true,
responsiveSlidesKey: "-",
responsiveWidth: 1000,
touchSensitivity: 15
});
});

```
