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.

     window_->SetParent(NULL);
   }
   window_->set_ignore_events(!params.accept_events);
