grafx - Extensible Java Graphics Package Code

Getting RocketmanSND to compile with some clever hacks.

Reducing the MAX setting in PackString; halving it.

Making a revision to PackString whereby output is divided into multiple lines
if it's too long.

RocketmanSND won't compile because the string literal is too long. Trying to
fix.

Adding placeholder for RocketmanSND.

Adding audio/loops/rocketman.au. This audio is really better suited for a rate
of 16,000 and not 8,000.

Implemented pause/resume with the new audio dispatch thread framework and
surprisingly it not only compiles but also works, on first pass, without any
debugging effort (only studying code). This is an EXTREMELY COMPLICATED piece
of code and I need to rest a little, then have another look at it later.

Changing some control flow to avoid nesting in ModernAudioClip.

Renaming m_startedOffMillis to m_startedMillis because the data type is being
changed from int to long. This simplifies the code, but limits easy access to
this data member from multiple threads (which wasn't being employed anyways).
m_constrTimeMillis is being removed as well because it is no longer needed.

Using more advanced thread communication in setting of m_startedOffMillis.
