No-duration tweens:
* Tweens with a 0-second duration set the property immediately at the time of the tween call, or after any delay.
* This behavior has advantages and disadvantages. It is recommended that you purposefully use 0-second tweens * to set properties that are handled by the engine at any time in your program, since this will * effectively stop any potentially running tweens on that property. (Trying to set a property while it is being tweened * usually has no effect.) However in some dynamic programs you may want tweens that end up having no duration to also * skip their delay and/or callbacks and events - this can be controlled with SKIP_LEVEL.

* 2. No-change tweens:
* Tweens at times end up being generated that affect no visual change. Normally the actionscript_video_com_mosesSupposes_fuse_ZigoEngine operates under its * legacy behavior, which is to run such tweens regardless. This can be good (the program's sequence will continue * on a schedule) or bad (the tween is essentially invisible and will fire callbacks and events on update and end, * which may cause confusion). In some cases you may want to skip past tweens that don't do anything visually.
