I suppose we should work to thread the layout scope even further. Pretty big
change that though. *puts on mental TODO*

 
     removeFromCacheAndInvalidateDependencies(object, needsLayout);
 
     // Invalidate resources in ancestor chain, if needed.
     LayoutObject* current = object->parent();
     while (current) {
         removeFromCacheAndInvalidateDependencies(current, needsLayout);
 
         if (current->isSVGResourceContainer()) {
             // This will process the rest of the ancestors.
             toLayoutSVGResourceContainer(current)->removeAllClientsFromCache();
             break;
         }
 
         current = current->parent();
     }
 }
 
 }
