[fxtf-drafts] [motion] default reference box for basic shape

ewilligers has just created a new issue for https://github.com/w3c/fxtf-drafts:

== [motion] default reference box for basic shape ==
[offset-path](https://drafts.fxtf.org/motion-1/#offset-path-property)
should specify the default reference box for a basic shape.

For comparison:

[shape-outside](https://drafts.csswg.org/css-shapes/#shape-outside-property)
If <shape-box> is not supplied, then the reference box defaults to margin-box.

[clip-path](https://drafts.fxtf.org/css-masking-1/#the-clip-path)
If no reference box is specified, the border-box will be used as reference box.
