21beb236d2 Added support for occlusion of holes in occluders, and cleaned up the
interface to ShadowVolumeOccluders.

b3c26d5634 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.

5e85cd59ab 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.

247cb3ff7e 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.

e1ba8a6292 Added osg::CollectOccludersVisitor which is a helper class for finding active

348419219d Created new helper class osg::CullStack to handle the accumulation of projection,
