* Add basic support for enumerating computed styles
The old code was so broken, it was enumerating the style attribute
instead of the computed styles.
So this patch implements a basic enumeration, but not including custom
properties whose computed value is not the guaranteed-invalid value.
* Feedback
This deviates from css2, but it's mandated by css-align, and matches
what other browsers do when no margin is 'auto'.
When some margin is 'auto', this should keep the proper round-tripping
behavior that Gecko and WebKit lack, and Blink recently adopted.

They are not transitionable:
https://drafts.csswg.org/css-transitions-1/#transitionable
There are some new failures in background-image-interpolation.html,
but I think the test is wrong, because it expects background-image
to be transitionable, even though the spec defines it with a discrete
animation type.
