Firefox doesn't render gifs properly when fill mode is on

[mattandrews]

It looks to me like this line is the offending one – this.element.style.webkitTransform should probably be this.element.style.transform, right? If I copy the calculated scale value from Chrome and manually apply it in Firefox it works.

Incidentally, when I've been playing with this (eg. a grid of 8 complex gifs), Firefox miscalculates the scale by around a factor of 10, but only occasionally. This is probably my implementation rather than x-gif itself, but thought it was worth noting.

... so it turns out @itsananderson already identified (and fixed!) this over a year ago in #25 – is there a reason it's not been merged or should I just switch to his fork?
