2nd big refactoring.

Goals are orthogonal components for:
	- OS Windowing system
		- NEWT, X11, Windows, MacOsX
	- GL Windowing GLUE
		- EGL, GLX, WGL, CGL
	- GL profiles
	- core and util packages
	- generate all Java components from any platform

All above goals are achieved.

TODO:

- Native compilation fix and test
- Check/Fix Win32, MacOSX and the mobile devices
- ..

+ *   <li>If the function is a GLU core function then the function is first
+ *   cross-referenced with the GLU specifications to find the minimum GLU
+ *   version required to <i>call</i> that GLU function. Then the following table
+ *   is consulted to determine the minimum GL version required for that version
+ *   of GLU:
+ *   <ul>
+ *   <li> GLU 1.0 requires OpenGL 1.0
+ *   <li> GLU 1.1 requires OpenGL 1.0
+ *   <li> GLU 1.2 requires OpenGL 1.1
+ *   <li> GLU 1.3 requires OpenGL 1.2
+ *   </ul>
+ *   Finally, <code>glGetString(GL_VERSION)</code> is used to determine the
+ *   highest OpenGL version that both host and display support, and from that it
+ *   is possible to determine if the GL facilities required by the GLU function
+ *   are <i>available</i> on the display.
+ *
+ *   <li> If the function is a GLU extension, the function name is

+ *
+ * <b>GLU_TESS_COMBINE</b>
+ * <UL>
+ *   The combine callback is called to create a new vertex when the
+ *   tessellation detects an intersection, or wishes to merge features. The

+ *   combination are given by <i>weight</i>; these weights always add up to 1.
+ *   All vertex pointers are valid even when some of the weights are 0.
+ *   <i>coords</i> gives the location of the new vertex.<P>
+ *
+ *   The user must allocate another vertex, interpolate parameters using
+ *   <i>data</i> and <i>weight</i>, and return the new vertex pointer
+ *   in <i>outData</i>. This handle is supplied during rendering callbacks.
+ *   The user is responsible for freeing the memory some time after

+ *   called.<P>
+ *
+ *   For example, if the polygon lies in an arbitrary plane in 3-space, and a
+ *   color is associated with each vertex, the <b>GLU_TESS_COMBINE</b>
