Bug 1031: Remove Deprecated Classes and Methods (JOGL)

Removed Deprecated Class:
  - com/jogamp/opengl/util/TGAWriter.java
    - Use TextureIO w/ .tga suffix

  - com/jogamp/opengl/util/awt/Screenshot.java
    - Use:
      - com.jogamp.opengl.util.GLReadBufferUtil, or
      - com.jogamp.opengl.util.awt.AWTGLReadBufferUtil
      The latter for reading into AWT BufferedImage

      See: TestBug461FBOSupersamplingSwingAWT, TestBug605FlippedImageAWT

  - javax/media/opengl/GLPbuffer.java
    - Use:
      caps.setPBuffer(true);
      final GLAutoDrawable pbuffer = GLDrawableFactory.getFactory( caps.getGLProfile() ).createOffscreenAutoDrawable(null, caps, null, 512, 512);
    - See: TestPBufferDeadlockAWT, ..

Removed Deprecated Methods:
  - Constructor of AWT-GLCanvas, SWT-GLCanvas, AWT-GLJPanel
    with argument 'final GLContext shareWith'
    See GLSharedContextSetter, i.e. glCanvas.setSharedContext(..) !

  - GLDrawableFactory.createOffscreenAutoDrawable(..)
    with argument 'final GLContext shareWith'
    See GLSharedContextSetter, i.e. offscreenAutoDrawable.setSharedContext(..) !

  - GLDrawableFactory.createGLPbuffer(..),
    see above!

  - com.jogamp.opengl.util.av.AudioSink 'enqueueData(AudioDataFrame audioDataFrame)',
    use 'enqueueData(int, ByteBuffer, int)'

  - GLSharedContextSetter.areAllGLEventListenerInitialized(),
    migrated to GLAutoDrawable !

  - GLBase's
    - glGetBoundBuffer(int), use getBoundBuffer(int)
    - glGetBufferSize(int), use getBufferStorage(int).getSize()
    - glIsVBOArrayBound(), use isVBOArrayBound()
    - glIsVBOElementArrayBound(), use isVBOElementArrayBound()

  - NEWT MouseEvent.BUTTON_NUMBER, use BUTTON_COUNT
