Subject: - Fixed rootrel.build usage, this works properly through gluegen,
 jogl-demos and this build.   You can say -Drootrel.build=build-x86_64 for
 example.

- Fixed jogl-demos in regard to this changeset

- Gluegen
    - Fixed gluegen BuildComposablePipeline's 'getGL*' methods.
      Now they return 'this', otherwise the pipeline would be broken/removed.

    - Add BuildComposablePipeline CustomPipeline, which allows customized
      class composition with an interface (to be wrapped),
      prolog class and the downstream class.

    - Add GlueGen (incl. ant task) 'outputRootDir' to be able to set a
      top output root dir via ant / commandline.

- GL fixed function
    - Package 'javax.media.opengl.sub.fixed.*' defines some fixed function interfaces.
      This allows partitioning of custom implementation.

    - Using gluegen's new CustomPipeline to compose a GLFixedFuncIf implementation,
      using a GL downstream and a GLFixedFuncHookIf prolog.
      The latter implements the fixed functionality.
      Example is the GLFixedFuncImpl.
        gl.getContext().setGL( new GLFixedFuncImpl(gl, new FixedFuncHook(gl.getGL2ES2())) ) ;
      or
        gl.getContext().setGL( new GLFixedFuncImpl(gl, gl.getGL2ES1()) ) ;

   -  The example GLFixedFuncHookIf impl FixedFuncPipeline/
      can be instantiated with custom shader code.


- ES2 and all other interfaces only contain the original functionality,
  besides minor convenient data access methods.

- Fix: GL2ES2 createCompileShader() and createLoadShader() is moved to ShaderCode util class.

- Updated PMVMatrix

- Add: GLAutoDrawable.setContext() .. and all it's implementations
  Necessary to set a new GLContext.

- Add: GLContext getAttachedObject(int) and putAttachedObject(int, Object),
  to allow the user to attach application specific and TLS sensitive objects to the GLContext.
