// @description    The new downloads button has a nice progress animation (even if the conic-gradient anti-aliasing isn't great) but I'm not at all a fan of the new ultra-thin icon style itself. I've invested a lot of energy into restoring the previous, bolder icons, so I can't leave the downloads button untouched. The whole DOM structure has fundamentally changed so restoring the old animations was quite a challenge. I decided to keep the progress animation and simply thicken it, but the other animations are modified versions of the old ones. Changing the animations can be done in CSS, but it will break the javascript method that switches from the download icon to the progress animation, because it's listening for "animationend" events and checking the animation name. The original animations all had different names, while the new ones use the same name. We can't really make this work with just one set of keyframes, since the start and finish animations are very different. One is a "dip" and the other more like a "blip," so I had to change the animation names, which requires changing the callback. This standalone version of the script doesn't require any additional files, other than a script loader. It will modify the callback and load the CSS and icons itself. If you use my theme or my userChrome.au.css file, you should get the other version, since it's better to load icons from file than from data URIs.
