grafx - Extensible Java Graphics Package Code

Changing default options in Donut.

Changing the fine mesh tesselations a tad.

Making some optimizations to Donut. Mostly just going through it with a fine-
toothed comb, adding comments, etc.

Adding printOptions() to Donut.

Adding launch-3d-donut-demo.sh script.

Adding launcher scripts for 2D polygon filling and line drawing demos.

Adding scripts/clean.sh.

Adding some launcher scripts and adding svn:ignore property for generated build
directory.

Adding 2D rendering demo code. Already made some changes to SimpleDemo.

Adding class com.nerius.grafx.d3.demo.Donut class and ALL OF THE DEPENDENCIES
to get it to run. A library is useless without proof that it can work, and a
demonstration of how it works.
