The 'body' of seamless IFrames should default to 'margin: 0'
https://bugs.webkit.org/show_bug.cgi?id=90834
Reviewed by Antti Koivisto.
Source/WebCore:
Documents displayed in seamless iframes should override the 'body'
element's normal 8px default margins with 0px, in order to ensure that
contents are displayed flush with the boundries of the seamless box.[1]
This patch does so by adding a new pseudoclass to allow the user agent
stylesheet to specify a different margin for seamless documents.
