from: DEEP_COPY_STATESETS = 8,
to: DEEP_COPY_STATESETS = 1<<3,
showing clearly that this isn't the _value_ 8, but the _bit_ 8. this is an old pattern i see (and like to promulgate) to make code a bit more readable and maintainable.

From Robert Osfield, refactored the FrameBufferObejcts::_drawBuffers set up so that its done
within the setAttachment method to avoid potential threading/execution order issues.
Introduced code in BoundgingSphere, BoundingBox, ProxyNode and LOD to utilise the above settings.
Added Matrix::value_type, Plane::value_type, BoundingSphere::value_type and BoundingBox::value_type command line
options that report where the types of floats or doubles.
and a new scheme for computing the scaling when using autoscale that introduces smooth
transitions to the scaling of the subgraph so that it looks more natural.
Attached is a fixed version of OverlayNode.cpp. I fixed CustomPolytope::cut( osg::Plane ) method. Bug was apparent in such scenario:
Let P1 be some random frustum polytope
Let P2 be the polytope that was created from P1 bounding box (P2 contains P1 entirely)
Then ignoring precision errors: P1.cut( P2 ) == P2.cut( P1 ) == P1. But this condition was not always met. Cut failed when some of the polytope reference points happened to lie exactly on some intersecting planes in both P1 & P2 (plane distance was = 0).
I only use CustomPolytope for my shadowing stuff so I did not test how this affects rest of OverlayNode.cpp.

Also attached is a minor precision improvement for osg::Plane intersect method (double version).
----3----
I have also one observation regarding osg::Plane - There are two intersect vertices methods (float and double flavour):
inline int intersect(const std::vector<Vec3>& vertices) const
inline int intersect(const std::vector<Vec3d>& vertices) const
I guess osg::Plane won't compile when someone changes default vec3 typedef to vec3d. Shouldn't the first method be changed to use vec3f explicitly ? Ie:
inline int intersect(const std::vector<Vec3f>& vertices) const"
pbuffer functions or exactly ask for the extensions we need to call the
apropriate glx extension functions for and around pbuffers extensions.
The glx 1.3 version of this functios are prefered. If this is not pressent we
are looking for the glx extensions and check for them.
Prevously we just used some mix of the glx 1.3 functions or the extension
functions without making sure that this extension is present.
