[vtkusers] vtkMDI + SetParentId() + SetWindowId()

Just for clarification: You are not forced to use a call to
SetParentId() when trying to catch the double click message. It also
works fine with a single

   this->renWin->SetWindowId(this->GetSafeHwnd());

instead of using

   this->renWin->SetParentId(this->m_hWnd);

Maybe this is the intended way to subclass a MFC window.
