/**
 * Integer time frame in milliseconds, maybe specialized for texture/video, audio, .. animated content.
 * 

* Type and value range has been chosen to suit embedded CPUs * and characteristics of audio / video streaming and animations. * Milliseconds of type integer with a maximum value of {@link Integer#MAX_VALUE} * will allow tracking time up 2,147,483.647 seconds or * 24 days 20 hours 31 minutes and 23 seconds. *

*

* Milliseconds granularity is also more than enough to deal with A-V synchronization, * where the threshold usually lies within 22ms. *

*

* Milliseconds granularity for displaying video frames might seem inaccurate * for each single frame, i.e. 60Hz != 16ms, however, accumulated values diminish * this error and vertical sync is achieved by build-in V-Sync of the video drivers. *
