Changed the osg::LightSource so its Light attribute is now generalised to
...
be a StateAttribute. This allows alternative implementations of Lights
other than the standard osg::Light.

Added support for occluders occluding other occluders, which helps reduce
...
the number of occluder that will be used in cull traversal to only the
ones that will be effective. Note. Holes in occluders arn't handled in
this occluder occlusion test, will implement this later.

Added the length argument to a std::string argument, under Linux it

compiled with the default value npos, under Windows it broke the build,
add the npost excpilicity should get round this difference in implementation.

Rewrote the FileUtils support for data and library file paths, moving the
...
storage of the path lists into osgDB::Registry, and changed the data
structor from a char* to a std::deque. Changed a names of couple of the
convinience functions in osgDB/FileUtils to better reflect the two
public FilePathList's - DataFilePathList and the LibraryFilePathList.
Added support into the osgDB::Registry::readNode/Image/Object methods
for pushing and popping the path of the current file being loaded.

Added occluder hole test code into the osgoccluder demo. The code works,
...
but I've commented it out right now as the Geode physically representing
the occluder doesn't yet have a hole in it - just a cosmetic thing.

Checked in Macro Jez's additions to osgText to support .osg IO make it
...
a fully functioning NodeKit.
Also reimplement notify() to try an prevent a crash which has been caused by
to objects in notify.cpp being initiliazed twice, the second time the auto_ptr
holding the dev/null ofstream was being initilized to 0.

Checked in migration from osgUtil based GUIAdapter code to Neil Salter's
...
osgGA (Gui Abstraction). This may break users code, but all it should
require to fix the builds should be a change from
osgUtil::CameraManipulator (etc) to osgGA::CameraManipulator and
include <osgUtil/CameraManipulator (etc) to osgGA/CameraManipulator and
the extra dependency of the link line.
