So, I looked at code in the aura shell, and I believe you may be able to safely
add a new TYPE_PANEL to InitParams::Type, and a corresponding type to WindowType
in ui/aura/client/window_types.h. I don't see any code that is triggered on
TYPE_WINDOW that is relevant to panels.

Done.

   // TODO(beng): do this some other way.
   delegate_->OnNativeWidgetSizeChanged(params.bounds.size());
   can_activate_ = params.can_activate;
   DCHECK(GetWidget()->GetRootView());
   if (params.type != Widget::InitParams::TYPE_TOOLTIP) {
     tooltip_manager_.reset(new views::TooltipManagerAura(this));
   }
