option to the osgoccluder demo.
First the osgGA classes have been generalised a little to better support
new GUIEventHandler subclasses.
Second osgGLUT has a new option for registering a user defined event handler,
the allows the application to add externally extra options to the osgGLUT viewer.
Third, the osgoccluder demo now works in two modes. The original create
four occluder sides to wrap an loaded model, the second an interactive
mode which allows the users to add occluders to the model by pointing
to points and pressing 'a' to add a point, the 'e' to end the occluder
polygon, polygons must be convex, planer and be defined in an anitclockwise
order. To start the osgoccluder in this mode one simple runs it with the
'-c' option. Run osgoccluder with no parameter to get a list of options.
is orientated towards the viewer.
Changed the lightmodel ambient level to 0.1,0.1,0.1 instead of 0.0, so that
a small amount of ambient lighting is available to render back surfaces.
The osgreflect and osgprerender suffered unexpected behaviors because of
no lighting on the backfaces.
all unsed texture units can be turned off simply within Drawables such
as Geometry and GeoSet. This can be used to prevent bleed of arrays from
one object to the next - which can cause crashes.

Have renamed osg::Transparency osg::BlendFunc to bring it in line with
the
rest of the OSG's StateAttribute classes which are named after their
OpenGL counterparts. include/osg/Transparency still exists and is
simply
a typedef to BlendFunc and is enclosed in a #ifdef USE_DEPRECTATED_API
block.
The matrix methods in the osg::Transform class have been
moved/replicated in
a osg::MatrixTransform sublcass from osg::Transform. The old matrix
functionality is still present in the osg::Transform class but is guard
by #ifdef USG_DEPRECATED_API blocks. One should now think of
osg::Transform
as being a Transform Node base class. MatrixTransform has all the
functionality of the original Transform class, so should be used
instead.
