grafx - Extensible Java Graphics Package Code

Carrying over a line drawing bug fix from com_nerius_grafx, where the bug had
been fixed in 2009 or thereabouts. The fix had not been "imported" into
blockout until now. I recently fixed a bug that may be related, by offering a
cheesy workaround. May have to back out the cheesy fix from blockout now.

In GrafxPolyFillDemo.java, moving a single line of code, because it had been
moved in the com_nerius_grafx "duplicate" code area.

Carrying over a change that was made in com_nerius_grafx "duplicate" code.
GrafxLineDrawDemo.java changed, one line moved.

Changing clip used to update a block freeze event, expanding by one pixel in
each direction, to circumvent a rare bug that was occurring.

Changing sleep times between blockout board events in MainBugTest.java.

Adding MainBugTest.java, which is a snippet of code that exposes a bug related
to line drawing the well.

Upping size of frame.

Changing brain overload level. A bit easier.

Removing an extra newline at end of file.

Very minor changes to LaunchTestGameLogic.java - adding comma in copyright
notice and upping the dimensions of window a bit.
