From Wojciech Lewandowski, "ref_ptr usage changes made on 9th of June broke VirtualProgram used in osgShaderCompositor example. Taking the opportunity I modified the code a little to use earth sphere as default model. Cow.osg used previously was not looking good in advanced example. I also changed default to advanced example, because its more informative with labels describing virtual programs used to render the objects."
