  // For some reason, the _COM_SMARTPTR_TYPEDEF macro causes errors when it is used in
  // a WinRT build. A bug submitted to Microsoft Connect was confirmed, its cause pinpointed
  // by a member of the Windows C++ libraries team, then 'Deferred' and forgotten about.
  //
  // Windows 8 now ships with the buggy header and it will probably not get fixed ever because
  // it might change the behavior of existing code (eg. people relying on a compilation error
  // for whatever reason might suddenly get perfectly working code). Hurray.
  // http://connect.microsoft.com/VisualStudio/feedback/details/751127
  //
  // Now Microsoft added a third smart pointer, Microsoft::WRL::ComPtr, with yet another
  // QueryInterface() concept. Its design isn't as crappy as the CComPtr and CComQIPtr,
  // but obviously whoever wrote it forgot about _com_ptr_t.
  //
  // This new member of the COM smart pointer zoo, Microsoft::WRL::ComPtr, only works in
  // C++/CX and is far less elegant than _com_ptr_t, so we use _com_ptr_t. End of story.
