grafx - Extensible Java Graphics Package Code

Drawing vertices first, in Donut.

Some little changes here and there. A big change is that the pixel is first
come takes precedence in the z buffer. Other stuff drawn later at same z value
will not be drawn.

Removing some error checking code in Donut.

Fixing the bug in drawPoint(), which was related to normals and ununiform
scale.

Making xCoord and yCoord 'final' in drawPoint() in RasterDepthGraphics.

Adding a bit of temporary error checking code which makes sure that the facet
normals are correct.

First pass at revisiting the drawing of polygon vertices. Not tested, but
compiles.

Making getPointAlias() a static function, because it's algorithm-related, and
not state-related.

Making a preliminary implementation of VectorUtils.sliverContainsSamplePoint().
Had to make some necessary changes to VectorUtils, to the new functions there.

Dropping the EPSILON back face culling from drawPoint(). Adding function
dotProductXY() to VectorUtils.
