grafx - Extensible Java Graphics Package Code

Making a first pass at the NewBlockStartsEvent logic. It's complete but
untested.

Making incremental progress towards the NextBlockListener logic in
SynchronizedModeGamePlayback.

Spiffy up SynchronizedModeGamePlayback a little bit, getting ready for reading
new block starts events for NextBlockListener.

Removing src/com/nerius/grafx/d2/Bug.java since the bug seems to be fixed.

Removing error data, since the bug is now probably fixed.

There was a definite problem in the polygon clipper for fillPolygon(). We now
ensure that the start edge starts strictly inside the clip boundary, not just
on the border.

Some more minor work on comments.

Adding some basic comments to FloatPolyEdge.

This is the sort of output print block that reported error.

Starting to add NextBlockListener to SynchronizedModeGamePlayback.
Will need to sift through stream, then rewind.
