OpenSceneGraph/include/osgManipulator/Scale2DDragger
Robert Osfield 0adf26ec6e From Wang Rui, "The osgManipulator serializers are ready now. I need to modify the
META_OSGMANIPULATOR_Object macro to ensure these classes could work
with their wrappers, and a few naming styles should be changed as
well. Fortunately everything seems to compile fine under Windows and
my new Ubuntu system.

And I finally find the problem of the
serializers/osgTerrain/Terrain.cpp, it just missed an "osg::Group"
before "osg::CoordinateSystemNode" indicator. With the small fix
attached now VPB could generate terrain with osgt/osgb formats."
