- changed FGSubsystem::update(int) to FGSubsystem::update(delta_time_sec); the argument is now delta time in seconds rather than milliseconds - added FGSubsystem::suspend(), FGSubsystem::suspend(bool), FGSubsystem::resume(), and FGSubsystem::is_suspended(), all with default implementations; is_suspended takes account of the master freeze as well as the subsystem's individual suspended state - the FDMs now use the delta time argument the same as the rest of FlightGear; formerly, main.cxx made a special case and passed a multiloop argument - FDMs now calculate multiloop internally instead of relying on main.cxx There are probably some problems -- I've done basic testing with the major FDMs and subsystems, but we'll probably need a few weeks to sniff out bugs.
