* Integer time frame in milliseconds, maybe specialized for texture/video, audio, .. animated content.
* <p>
* 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.
* </p>
* <p>
* Milliseconds granularity is also more than enough to deal with A-V synchronization,
* where the threshold usually lies within 22ms.
* </p>
* <p>
* 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.
