70861ef70e Converted osg::LOD from used n+1 successive ranges to n min/max ranges,
one min/max pair per child. Converted the rest of the OSG to use the new
osg::LOD node.

f11410928f Simplified the depth calculation code in CullVisitor so that it always computes
the depth of all drawables, so that it is always safe for RenderBin sort routines can use
these values directly.

Add an example of a RenderBin::SortCallback to sgv.cpp.

12226e4371 Converted the instances of const built in types being returned from methods
and passed as paramters into straight forward non const built in types,
i.e. const bool foogbar(const int) becomes bool foobar(int).

b23a48a763 Renamed the osg::EarthSky to osg::ClearNode to make it more obvious what
role it has play and make it more relevant to non vis-sim applications.

d2aa4270ce Added support for CullVisitor to contain a osg::State. This used when
cull Callbacks require the contextID for  doing operations on texture
objects, for example.  Modified CullVisitor SceneView and Drawable

348419219d Created new helper class osg::CullStack to handle the accumulation of projection,
modelview and culling sets, to be used during travesal of the scene graph, such
as the cull traversal.

5feba17410 Added new osg::OccluderNode which subclasses from osg::Group, and will
provide hooks for adding ConvexPlanerOccluders to the scene.

553db68bc4 Added osgUtil::CullVisitor::getCurentRenderGraph() and getRootRenderGraph()
methods which replace getRenderGraph(). Small changing of order of push/pop
of StateSet's in SceneView to clean things up.

d140decb44 Added pixelSize method to CullVisitor, and converted small feature
culling to use the pixelSize method instead of a ratio of radius to
distance from eye point.  setSmallFeatureCullingPixelSize() method
has also been added to provide the user with finer control of small
featyre culling.

f0e7e8e48b Removed CullViewState from the distribution, moved CullViewState::CullingMode
into CullVisitor, and then removed all references to CullViewState from other
parts of the scene graph.

use osg::Transform::ComputeTransformCallback.

56dc083330 Added support for compute the near and far planes and then applying to
the current projection matrix into CullVisitor itself.  Similar code to
support this has been moved out of SceneView completely.

Added Matrix:: infront of the definition of the static
osg::Matrix::inverse(Matrix) method which was missing.

e17261c45f Changed the osg::Billboard comution so that it get passed in the current
modelview matrix rathan than an identity matrix, this matrix is then modified
locally.

Changed the osg::Matrix set methods so they are inline.

Added a few useful comments to MemoryManager.cpp to help people understand
the assert's better.

f8340f9ef5 Removed the cached matrices from osg::Camera, so that
osg::Camrea::getModelViewMatrix() and osg::Camera::getProjectionMatrix() are
calculated on the fly.  Removed various redudent methods, including the
project and unproject methods which are better supported within osgUtil::SceneView.

Added a computeWindowMatrix() method to Viewport, to make it easier to construct
a MV*P*W matrix for converting local coords into screen coords and visa versa.
Converted SceneView and CullVisitor to use this new method.

f2ffbdd469 Copied NewCullVisitor over top of CullVisitor and then removed NewCullVisitor.
Added some defines to Image in prep for writing code to determine how big a
pixel is.

3351306d80 Added new osg::Projection node, and osgUtil::NewCullVisitor which are work
in progress for the new support for controlling the projection matrix from
within the scene graph.

Also Added osg::State::getClippingVolume(), getProjectionMatrix() and
getModelViewMatrix() with allows drawables to access the current projection,
and model view matrices and the view frustum in local coords to the drawable.

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.

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.

cb8025d913 Renamed osg::Matric::makeIdent() to osg::Matrix::makeIdentity() to make
it consistent with the rest of the osg::Matrix naming.  Updated OSG
distribution to account for new name.

Added support for the STATIC/DYNAMIC osg::Transform::Type to the .osg
ASCII reader/writer plugin and the flt reader plugin.

Removed the non cost version of osg::Transform::getMatrix() as this could
by pass the dirty mechinism.
