- // This small animation shows the advantage of being able to create
- // cyclic animations using the +KC command line switch or the
- // equivalent INI-file setting.
- //
- // Trace this animation with and without the cyclic animation option
- // to see the difference. Without the cyclic animation flag set the
- // first and the last frames are the same.
