> Support offset-path: ray() function <size> and <contain>.
>
> As per https://drafts.fxtf.org/motion/#offset-path-property
> when offset-path is specified with ray() function and offset-distance
> is expressed as a percentage, the <size> part of the property should
> define the path length.
>

> equal to path length.
