Hi All,

I believe we must be pretty close to stable 3.4.0 release as I had only one
submission to merge since rc8 that I tagged at the end of last week!  The
revision was to make osgViewer's X11 PixelBuffer query for the SGIX
extensions at runtime rather than use them directly at compile time.  This
change is intended to make it possible to run the OSG on X11 systems that
don't provide support for the SGIX extensions.

   - Zip file containing source code : OpenSceneGraph-3.4.0-rc9.zip
   - Subversion tag for 3.4.0-rc8 : svn co

As before I'd like testing out on as many platforms as we can get, positive
and negative feedback is required so I know where we are at.  If there
aren't any reports of problems I'll go for the 3.4.0 on Wednesday.

    * include/osgViewer/api/X11/PixelBufferX11,
      src/osgViewer/PixelBufferX11.cpp: From Andy Skinner, "Someone was
      using our code on a system that does not seem to have the SGIX
      symbols used in osgViewer.cpp.

      I used osgSetGLExtensionsFuncPtr to remove the symbols. I don't
      know how to test this path, but it did remove the symbols from
      libosgViewer.so. I have also not been able yet to see if that was
      sufficient for our customer.

      I did this by looking at other cases, and I tried to follow some
      of the same practices in PixelBufferX11, like using _useSGIX in a
      similar way to the previous _useGLX1_3."
