Re: [svgwg] Add a method to return the path direction (tangent) angle at a given distance

Oops, again! Animation software isn’t as consistent as I thought.

I just checked how [Apple Motion](https://www.apple.com/final-cut-pro/motion/) works, and it uses the direction of the next segment at vertices (and behaves strangely at the end). Here’s a screen capture of it:

![apple-motion5-mp](https://user-images.githubusercontent.com/6185066/28773231-6436d620-75f1-11e7-8045-ec45c808422c.gif)

I don’t have access to After Effects right now, but it worked the same way as CSS Motion Path when I tried it. Unfortunately, [After Effects help documentation about motion paths](https://helpx.adobe.com/after-effects/using/assorted-animation-tools.html) doesn’t go into details like that.

It would be nice to know why the Chromium team decided to implement motion paths the way they did. When I [requested the addition](https://github.com/w3c/fxtf-drafts/issues/108) to CSS Motion Path, I just wanted Chrome’s behavior to be documented somehow.
