Re: outlines should not affect scroll dimensions.

I added a test case to http://hpaa.com/firefox/shadow.htm. Opera and
Safari/Chrome render outlines per spec, with no effect on scrollWidth. With
Firefox, however, the outline affects scrollWidth. I don't have IE8

Maybe it would be helpful to imagine 'effects layers' above and below each
element. Overflow has no meaning on effects layers. Like the canvas, they
extend infinitely in 2 dimensions and clip only to the viewport.
