Undocumented scroll event argument positionX

[1deadpixl]

I stumbled onto the second argument passed to the scroll event, positionX, and am wondering if it's reliable to use it. It's not in the documentation, but it looks like it's been there since v2.0.0. Can I use this in production and not worry about it being removed in the future?

Here's the line where the scroll event gets returned with 2 arguments: progress, positionX https://github.com/metafizzy/flickity/blob/e2706840532c0ce9c4fc25832e810ad4f9823b61/js/animate.js#L94

Thanks!

It may not be removed, but I may change how it is calculated. I think I wasn't 100% certain I provided a good measurement. It may not work with wrapAround.

Is wrapAround compatibility on the roadmap? 😬 Having issues with different outputs for keyboard navigation and dragging! Progress seems to be inconsistent, too.
