/**
* A movie track gives access to the static resources of
* a movie (image and audio data, global informations).
*
* @author Werner Randelshofer, Hausmatt 10, CH-6405 Goldau, Switzerland
* @version 1.6.3 2011-09-09 Fixes computation of total duration.
*
1.6.2 2011-08-23 Animation frame duration was too long by 1 jiffie.
* method getTotalDuration always included time of wrapup frames, even if they
* were not played.
*
1.6.1 2010-10-06 Fixes infinite recursion in method isPlayWrapupFrames.
*
1.6 2009-12-24 Added support for color cycling.
*
1.5 2009-11-20 Added support for videos which don't have wrapup frames.
*
1.4 2005-09-16 Property "swapSpeakers" added.
*
2005-01-22 Method isPlayWrapupFrames added.
*
2004-12-30 Getter/Setter for nbPalettes added.
*
1.1 2003-04-25 Wrapup frames can be treated like regular frames.
*
