Swipe trails needs move faster.

@Nikhil.tom I found two things behind this. The trail was redrawn with a small built-in animation on every finger move, so it always ran a bit behind your finger. It was also drawn as straight segments between touch points, which is where the jagged corners came from. Now it follows the finger directly and the curves are smoothed. It also disappears faster after you lift your finger; before it kept crawling toward the end point for about half a second. This will be in 2.1.3, the next App Store update.

The swipe trail moves really well and I’m not noticing any jagged curves.
