grafx - Extensible Java Graphics Package Code

Adding beginnings of VIDEO-RECORDER.txt.

Making some minor code improvements when pausing for a certain time. These
section of code are quite intricate and tricky to get absolutely perfect.

Streamlining a bit by cutting out one call to Cronos.currentTimeMillis().

Showing how to use Cronos.Override. In SimpleGameLogic.

Move from System.currentTimeMillis() to Cronos.currentTimeMillis() in
LocalBlockoutBoard.

Forgot to call s_override.wait().

A first pass at Cronos.

Filling out the logic in Cronos. Next, I want to figure out how the enact a
change in the timekeeping. I don't want to pass objects around. I know it's
"unsafe" practice, but I want to be able to adjust this globally w/o passing
around any instance.

Rename GameChronos to Cronos, same string length as "System".

Adding a comment that conveys the purpose of GameChronos.
