067619d1fb Removed Lighting.cpp from repository, it is nolonger used and was just hanging 
around erroneously.

20e5751a4a Updated the osgUtil::Optimize so that the call to Optimize::StateVisitor is 
#ifdef out under Win32 and STL port isn't being used. This prevents crashes
due to MS's flacky STL implementation.

ccc3d3fd8a Added osgUtil::Optimizer which contains four visitor each designed for doing 
different types of optimization on the scene graph - state optimization,
flattening static transforms, combining LOD's and removing redundent groups.
The new Optimizer replaces the once seperate OptimizerStateVisitor.

54d490e24b Added support for specifying whether view frustum and small feature culling 
should be applied to a node or its child with the new osg::Node::setCullingActive()
flag.  A mechanism has been implemented so that if child has its culling disabled
then their parents, all the way up to the root are also have their culling
implicitly disabled.

The osg::CullVisitor has updated to take account of
both the explicit control via setCullingActive and the implicit culling
disabling through children being disabled.

This feature is useful for nodes which don't have a bounding volume to cull
against, earth sky implementations and light sources.

The default osg::Node::_cullingActive is true, i.e. culling is enabled by
default.

60d33f91f8 Reverted Bryan's changes to FrameStamp w.r.t std::tm structure which doesn't 
compile under Win32 and IRIX.  Will need to find another solution.

8aefce4524 Fixed then normal smoothing function in the .3ds loader and the 
osgUtil::SmoothingVisitor so that unused normals at left at 0,0,0 insead
of being normalized, which results in (nan,nan,nan).

0bce843960 Completed implementation of a the new CombineLODsVisitor, ideal for use with 
the .flt loader.  Code is stuff currently in sgv, but will be moved out once
more testing has been done.

OrientationConverter and the flattenTransformVisitor in sgv.

659f7ad1ab Modified Veiewer.cpp so that when toggling the light with 'l' the light can 
be overrided to off and overrided to on, previoulsy it only overrided to off.

from Robert.

59077fed15 Added support for automatic creation of global StateAttributes to osg::State, 
these global attributes are created by cloning any attributes which are
applied during rendering, the clone in a shallow copy, which will set up
default valus for that attribute.  This should prevent attribute bleed
from one stateset to the next when the global StateSet doesn't contain
an attribute used within the scene graph.

right hand rule rotation.

7c54b58306 The writeImage/Object/Node methods in the .osg and .pfb reader/writer didn't 
have the new ReaderWriter::Options* structure passed to them, which meant the
the virtual functions didn't bind with the new base class methods and wern't
called on a write.

d66bfdbbc5 Updated pfb loader to load pfb files into osg. Still broken for loading osg 
files into Performer, however.

Robert Osfield
06dafa487e Added osgDB::ReaderWriter::Options class to the ReaderWriter base class, support 
for settings options in osgDB::Registry, and added the paramter to all of the
reaader/writer plugins.  The Options structure by default has an string attached
for packing basic options, however, it also can be subclassed to encapsulate
any users defined option data. In the later case both the client code *and*
the plugin need to be aware of subclass, the plugin will need to use
dynamic_cast<> to assertain its type.

45eefec3f0 Fixed TransformFunctor code so that it now uses the inverse of the 
transformation matrix to transform the normal.

6bb865af25 Fixed a bug in Matrix::invert(..) which did not set full_realised=true, 
so that one Matrices which had not previously be initialized we're
erronously initialized later in the code resetting it to identity.

39ea16aad7 Added osg::StateSet::merge(const StateSet& rhs) merges merges the modes and

0e8c2ef89b Quick 'n dirty fix to TrackballManipulator to get the rotations doing the 
right things after the Quat fixes.

c6f11afbf6 Quaternions were assigning inverted values during conversion to matricies. 
This is probably due to an error on the gamasutra web page demonstrating this.
It caused left-handed rotations rather than right handed rotations.  Should be
fixed now.

1e4a0cadf5 Changed the naming and calling convention of the new Drawable::AttributeFunctor 
and have updated GeoSet to use mutable values for the _numverts etc, allowing
osg::GeoSet::computeNumVerts() to be a const operation. osg::GeoSet::getNumVerts
is now a const once more, so avoiding compilation problems.  Also chaned the new
osgconv orientation code to use a Drawable::AttributeFunctor so it can work on
other Drawables other than just GeoSets.

to the the Drawable base class.

d5ed4e2305 Added an implemention of basic state sorting to the RenderBin, but have commented 
out the sort operation as Peformance benifit is currently negligable, will need
to improve on the sort functor to see real benifits.
