- // some properties can have 2, or 4 values relevant (x,y) or (t,l,r,b) for example
- //
- // this function provides support for those Lines, and is ported directly from 0.4
- // this is a lot of extra code for something so seldom used, so we'll put it here as
- // and optional core addition. you can create a new line, and use it during onAnimate
- // as you see fit.
