// Tips: Use with ImGuiDockNodeFlags_PassthruDockspace!
// The limitation with this call is that your window won't have a menu bar.
// Even though we could pass window flags, it would also require the user to be able to call BeginMenuBar() somehow meaning we can't Begin/End in a single function.
// So if you want a menu bar you need to repeat this code manually ourselves. As with advanced other Docking API, we may change this function signature.
