grafx - Extensible Java Graphics Package Code

Still simplifying the polygon fill, bit by bit.

Further optimizations in polygon filling, avoiding repeated array lookup.

Adding m_offset to RasterDepthGraphics but as I was incorporating it I realized
that there may be some performance gains to be had in fillPolygon(), the
simplest version of that method.

Still working on Javadoc in new constructor.

The new RasterDepthGraphics constructor now has five additional input
parameters.

Adding new constructor to RasterDepthGraphics. Not done yet. I think two more
"shift" parameters will be needed, and the implementation of course.

Fixing SteepLine with recent API changes.

Fixing OnePixelSteepLine with recent API changes.

Adding a massive, massive, detailed comment to RasterDepthPixBuff.drawPixel().
This is Javadoc.

Shows how beautiful and fast the WIREFRAME is. We're getting well over 500
frames per second.
