<h3>Log Message</h3>
<pre>Eliminate a request for layout every time an item is added to the stage of the graphics benchmark
https://bugs.webkit.org/show_bug.cgi?id=151289
Patch by Said Abou-Hallawa <sabouhallawa@apple.com> on 2015-11-13
Reviewed by Simon Fraser.
Cache the stage size when it is created instead of requesting every time
an object is added via clientWidth and clientHeight.
