grafx - Extensible Java Graphics Package Code

Allowing auClipSource to be null. Ensuring that it's okay with code fixes.

Making progress on PlaybackRecorder and LaunchPlaybackRecorder.

Adding initial thoughts for PlaybackRecorder. Very much work in progress.

Adding dependency on package com.nerius.game.util because of recent changes to
SynchronizedModeGamePlayback, which uses Cronos. The idea is to be able to
record smooth video, at e.g. 50 frames per second.

Now using Cronos in SynchronizedModeGamePlayback, instead of
System.currentTimeMillis() and Object.wait(millis). This is so that smooth
video can be made from recorded games. Still working on that part.

Simplify the suspend/wait logic in SynchronizedModeGamePlayback. This is a
real challenge to get concise and correct, with minimal lines of code.

Increasing dimensions of game. For the higher levels we need more clarity.

Adding comment of how Cronos is being used.

In SimpleGameLogic, no longer using Cronos. Cronos is useful for doing video
recordings. There is no reason for it to be used in SimpleGameLogic, so far as
I can see; in fact it may only open up possibility for cheats.

More work on VIDEO-RECORDER.txt.
