the iMuse implementation. This allows the termination sequence to be done BEFORE object destruction, so that the destructor is not making calls that may not be appropriate during object destruction. (Virtual functions were the concern, although I'm not sure any of that was happening anyway. Oh well, better to be safe than sorry.) I implemented an empty terminate() in the base class, but the other MusicEngine derivatives may have stuff in their destructors that should be moved to this method. I didn't check. svn-id: r10452
