c52207b637 Added new Transform::ReferenceType enum ABSOLUTE_RF_INHERIT_VIEWPOINT to support 
internal RTT cameras that wish to use the main cameras view/eye point for LOD and other
distance based tests.

f36bc69c58 Made the more of the OSG's referenced object desctructors protected to ensure 
that they arn't created on the stack inappropriately.

Split the implemention of Matrix up so that it is a simple no referenced counted
class and can be safefly created on the stack.  To support referenced counting a
seperate subclass now exists, this is RefMatrix which inherits from both Matrix and
Object.

ff8b4c001d Rewrote the osg::Drawable::AttributeFunctor and PrimtiveFunctor to make 
them more consistent with each other. This does mean an API change, so
dependanct code in the OSG has been updated accordingly.

Robert Osfield
8036901ea1 Rewrote osg:Statistics so that it is PrimitiveFunctor as is now completely 
decoupled from osg::Drawable.  The Drawable::getStats() virtual method
no longer exists.

Updated the Viewer to use the osg::Statistics incarnation and reformated stats
to clean it up.

c4c97a0f64 Moved the code referencing osg::BoundingBox::isValid() and 
osg::BoundingSphere::isValid() across to use the valid() methods, the later
being more consitent with other classes such as osg::ref_ptr<>.

cbeeeefdab Added osg::Drawable::PrimitiveFunctor and TriangleFunctor subclass for 
querrying the primitive data inside Drawables.  Moved various support
classes over from being osg::GeoSet based to osg::Geometry based.

84d2d01163 Added support for osg::MemoryManager which is based upon Paul Nettle's 
memory manager published at flipcode.com.  This can be turned on
with the OSG_USE_MEMORY_MANGER option which then uses custom global
new and delete operators as well as provide osgNew and osgDelete macro's
which add ability to log line and file from which calls are made.

Updated osg,osgUtil,osgDB,osgText and osgPlugins/osg to use osgNew/osgDelete,
and fixed memory leaks highlighted by the new memory manager.

8c9609b331 Added the fallback of intersecting with the a drawables bounding box, if the drawable 
isn't a GeoSet and hence supported by the IntersectVisitor's GeoSet primitive
intersections code.

c726abd773 Integrated fixes to the detailed depth calculation in the CullVisitor from 
Sasa, and fix to the IntersectVisitor's management of path from Sean.

a703130aa0 Have taken a few more steps towards support for view dependant transformations 
by adding a ComputeTransformCallback to osg::Transform, and have now removed
the recently added AutoTransform since it is nolonger required.  Have also
updated CullVisitor to account for the new ways for tracking transformation
matrices in the scene.

7b370fcb57 Made the LineSegment destructor protected to force users to create segments 
on the stack thus ensure that they arn't created locally and have their
memory deleted incorrectly.

Also updated the IntersectVisitor so that it no used osg::ref_ptr<> internally
for storing all data. Have also move the IntersectState helper class to inside the
IntersectVisitor which simplifies the external interface to the class.

06bd9fda5b Have made osg::Transform more extensible via additions of new getLocalToWorldMatrix() 
and getWorldToLocalMatrix(), computeLocalToWorld() and computeWorldToLocal()
methods.

Have updated the CullVisitor, IntersectVisitor and Optimizer to use the
new osg::Transform::getLocalToWorldMatrix() which has the same functionality
as the old getMatrix() but is now supports subclasses of osg::Transform
transparently.

Have added osg::PositionAttitudeTransform as subclass of osg::Transform
which manages the transform as position and attitude via a Vec3 and Quat
respectively.

acf256c466 UPdates to CullVisitor so that it keeps in sync with the new method paramter 
change in osg::Billboard.

Removed in instance of an object being passed () brackets, have removed the
brackets to avoid an amiguity with the compiler intepreting it as a function.
