Make zoom using ctrl+mouse wheel work in win aura. Windows non-aura had a hack that was a layering violation which sent a custom win32 message from RenderWidgetHostViewWin to WebContentsViewWin. Instead do this properly from RenderWidgetHostImpl to its delegate (WebContentsImpl), which works for both aura and non-aura windows builds.
