http://www.w3.org/TR/css3-box/#intrinsic0 (and also CSS2 10.6)
Since CSS doesn't attempt to specify the intrinsic width of a document in an
iframe, maybe HTML5 should specify that the intrinsic width of a document
- if the CSS width property is specified on the html element, the margin-box
of the page at that width (which may have overflow)
- else, if the CSS min-width property is specified on the html element, the
margin-box of the page at that width (which may have overflow)
- else, the smallest width the page can have without horizontal scrolling
and the intrinsic height of the document is:
- if the CSS height or min-height property are set, similar to above,
- else, the smallest height the page can have at the intrinsic width of the
document without vertical scrolling
