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