-void FrameView::updateCompositingLayersAfterStyleChange()

I considered removing this method and was on the fence. But, with changing the
update type to CompositingUpdateAfterCompositingInputChange it's clearly better.

-{
-    RenderView* renderView = this->renderView();
-    if (!renderView)
-        return;
-    renderView->compositor()->setNeedsCompositingUpdate(CompositingUpdateAfterStyleChange);
-}

     if (m_frame->settings() && m_frame->settings()->compositedScrollingForFramesEnabled())
         return renderView->compositor()->inCompositingMode();
     return false;
