grafx - Extensible Java Graphics Package Code

Carrying over RasterFloatGraphics changes that were identified and solved in
Blockout code, having to do with RasterFloatPixBuff.getWidth() and
RasterFloatPixBuff.getHeight() calls, in the seldom used constructor. This is
a one line code correctness change that leaves everything else intact,
including copyright notices and dates. It was a major bug, if used in that
way, with the RasterFloatPixBuff object.

Making some adjustments in TetrisBoard code, but still not happy with the
perspective view. These changes are to tidy up the rendering code, of well
boxes, somewhat.

In LocalBlockoutBoard, removing three cases where
RasterFloatGraphics.setClip(null) was being used, immediately after
instantiation of that RasterFloatGraphics. The constructor of that class calls
that method internally, so it was a wasted effort. We have to be careful to
not remove calls to this setClip(null) method when it's actually doing
something important, and not immediately following the constructor.

Fixing major bug where RasterFloatGraphics, when used with a
RasterFloatPixBuff object, would call that buffer's getWidth() method twice,
to get the width and height, instead of calling getWidth() once and
getHeight() once. This resulted in all sorts of clipping issues, it even
resulted in an ArrayIndexOutOfBoundsException in some cases, in the game of
Blockout.

Adding 'excellent9.blo' which has some latest and greatest features, in the
BLO file info string. I would like to still add the next block after the game
terminates, somehow.

Trying to fudge the perspective projection. I don't like the way this is
turning out.

Starting to make some corrections related to perspectives and rendering order.

Making some slight progress on Tetris. The orthographic projection is making
more sense now.

Clearing up some really confusing bits with respect to OrthographicProjection
and with respect to PerspectiveProjection.

Removing an extraneous whitespace from the code in LocalBlockoutBoard.
