| // 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. |
