<h3>Log Message</h3>
<pre>Fixed backgrounds don't paint in blurred inset areas
https://bugs.webkit.org/show_bug.cgi?id=135712
Reviewed by Simon Fraser.
Source/WebCore:
Background geometry calculations for fixed background need to use the larger
visible rect.
The first version of this patch caused a regression because it universally
adjusted the value for top to account for the inset whether or not the
viewportRect location was adjusted for the same. This version fixes that — those
two changes go hand-in-hand.
