  22 /* This is a small class which can be used by all ports
  23    to temporarily suspend the busy cursor. Useful in modal
  24    dialogs.
  25
  26    Actually that is not (any longer) quite true..  currently it is
  27    only used in wxGTK Dialog::ShowModal() and now uses static
  28    wxBusyCursor methods that are only implemented for wxGTK so far.
  29    The BusyCursor handling code should probably be implemented in
  30    common code somewhere instead of the separate implementations we
  31    currently have.  Also the name BusyCursorSuspender is a little
  32    misleading since it doesn't actually suspend the BusyCursor, just
  33    masks one that is already showing.
  34    If another call to wxBeginBusyCursor is made while this is active
  35    the Busy Cursor will again be shown.  But at least now it doesn't
  36    interfere with the state of wxIsBusy() -- RL
