Am I correct in guessing that the otherwise undefined value ID_SEPARATOR is
actually -1?  Interestingly, when Microsoft uses ID_SEPARATOR in MFC, it
uses 0 (see VC98\MFC\Include\AFXRES.H).

Is there a reliable way of querying wxWindows for an unused id?  One way of
doing it would be to increment starting at wxID_HIGHEST and to use
FindWindow to ensure that there isn't already something using the id (just
in case one of the randomly assigned ids happens to conflict).
