Subject: Working:     APX 2500         ES 2.0 + FixedFunction GLSL         ES

javax.media.opengl.glsl
    - Shader and program state management
    - Loading and merging shader source code
    - Loading binaries incl. auto selection
      of the binary file in respect to the supported binary format.
      I.e. in case of GLES2.GL_NVIDIA_PLATFORM_BINARY_NV:
        source: com/sun/opengl/impl/glsl/fixed/shader/ashader.fp
        binary: com/sun/opengl/impl/glsl/fixed/shader/bin/nvidia/ashader.bfp

      ShaderCode sc = ShaderCode.create( gl, gl.GL_VERTEX_SHADER, 1, FixedFuncPipeline.class,
                                         "shader", "shader/bin", "ashader");

      (Derivation of com.sun.javafx.graphics.gl2es2.ShaderUtil)

javax.media.opengl.sdk.glsl
    CompileShaderNVidia implements abstract CompileShader
      Toolkit to convert JOGL shader source to binaries,
      according to the location rule as described in ShaderCode.

    Example: Converts all fixed function shader to binaries.
      jogl/src/classes/com/sun/opengl/impl/glsl/fixed/shader/scripts/nvidia-apx/glslc-ff.bat

    (Generalization of com.sun.javafx.graphics.gl2es2.PrecompileNVShader)

Fixed function now resides in 'jogl.fixed.jar'
    - contains shader source and binaries
    - contains the implementation

GL2ES2:
    - removed glShaderBinaryOrSource()
    - use glCreateLoadShader() for binary and
          glCreateCompileShader() for source
    - using addition glGetError() check for shader upload/compilation
    - Skipping 'glValidateProgram' in case of ES2 and no compiler,
      since it fails on APX2500 ..
    - added: (caching the results)
        "public Set glGetShaderBinaryFormats()"
        "public boolean glShaderCompilerAvailable()"
    - shader-name and binary-data buffer: use 'remaining()'
      instead of 'limit()'

BufferUtil:
    - adding variant: <Type>Buffer new<Type>Buffer(<type>[] values, int offset, int len)

Working on all profiles ES1 + ES2 (CVM) with lighting:
    demo.es1.cube.Cube
    demo.es1.cube.CubeImmModeSink
    demo.es1.cubefbo.Main
    javabullet.demos.genericjoint.GenericJointDemo
