    <thetext>Implement rendering for CSS object-view-box 

This includes painting the view box sub region of replaced elements, using the view box dimensions as the element&apos;s natural size, and triggering the correct style invalidation on property changes. 

Spec: https://drafts.csswg.org/css-images-5/#the-object-view-box 
Depends on: https://bugs.webkit.org/show_bug.cgi?id=316220</thetext>
