Rudimentary standalone example using the fixed pipeline by Julien Gouesse

This program displays a simple 3D rendering of a polygon using JOGL. Please note though that this code is a demonstration of the use of JOGL and as such makes use of immediate mode drawing commands; this serves to show how the conventional C style API is used through JOGL, but it is strongly recommended to make use of modern OpenGL techniques.
