`<scale-up-animation>` animates the scale transform of an element from 0 to 1. By default it
scales in both the x and y axes.

Configuration:
```
{
  name: 'scale-up-animation',
  node: <node>,
  axis: 'x' | 'y' | '',
  transformOrigin: <transform-origin>,
  timing: <animation-timing>
}
```
-->

    is: 'scale-up-animation',

    behaviors: [
      Polymer.NeonAnimationBehavior

      } else if (config.axis === 'y') {
