f848c54ba3 Made the following name changes to Matrix and Quat to clean them up and make
the functionality clear given the name.  This will break user code unfortunately
so please be away of the following mapping.

  osg::Matrix::makeTrans(..)?\026 -> osg::Matrix::makeTranslate(..)
  osg::Matrix::makeRot(..)?\026   -> osg::Matrix::makeRotate(..)
  osg::Matrix::trans(..)?\026     -> osg::Matrix::translate(..)

  osg::Quat::makeRot(..)?\026     -> osg::Quat::makeRotate(..)

Also updated the rest of the OSG distribution to use the new names, and
have removed the old deprecated Matrix methods too.

a434abafd7 Fixes for IRIX build.
Updates to the osg::Transform, adding preMult and postMult methods and
deprecating the old preRotate,preTranslate,preScale.

Updated the rest of the OSG so that it nolonger uses the deprecated
osg::Transform nodes.

Renamed osgUtil::SceneView::setGlobalState() to
osgUtil::SceneView::setGlobalStateSet() so that the name reflects its
functionality better.  Updated osgGLUT::Viewer etc to cope with new
name change.

879a753ee2 Fixed osgUtil::Optimizer::FlatternStaticTransformsVisitor so that the
apply(osg::LOD) scaled the ranges in addition to transform the center
point and children.

d4926589dc Fixed bug related to osgUtil::Optimizer::FlatternStaticTransform::Visitor's
apply(Billboard& ) method which was apply the accumulated transform to
the billbaord geometry when it should have been applying the matrix without
the transform component.

5e6153b428 Added methods to support isNaN,isInfinte and valid to osg::Vec* and osg::Math,
and added a guard to IntersectVisitor which uses these new methods to prevent
invalid segments being added.

Robert Osfield
25c8b05914 Integrated Geoff Michel's updates to Stats code, whilest move all text rendering
back in the viewer from the Statistics header.

Added a osg::State::captureCurrentState(StateSet&) method and a copy constructor
to osg::StateSet.

7082abb8ad Added support for an osgUtil::SceneView::init() traversal which is called once
per scene view.  The user can attach a NodeVisitor to do init for them, or
leave it to the default which is to use the osgUtil::DisplayListVisitor
which compiles all display lists and texture objects.  The init traversal
is called automatically by the first call to either app() or cull(), so
should not be called by user code during initialization. This ensures
that a valid graphics context has been established before OpenGL is initialized.

osgUtil::DisplayListVisitor has also been updated to use a bit mask for options, and the addition of
compilation of texture objects (via StateAttribute::compile) has also been
added.

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.

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).

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

3da57d6d22 Added a osg::DegreesToRadians() and osg::RadiansToDegrees() method to osg/Math,
updated the ReaderWriterBMP.cpp (mods sent in my Geoff Michel) and
moved the osgUtil::Statistics to osg::Statistics in preperation to adding it
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.

2c6e85442b Integrated changes for MacOSX, submitted by Phil Atkin, with small mods by
Robert Osfield to maintain compatability under Linux.

7a7a26c2ea Added include/osg/EarthSky and src/osg/EarthSky to cvs.
Also move osg across to using radians for angular paramters by default.
By defining USE_DEGREES_INTERNALLY you can get the OSG to revert to
the old style degrees. This later feature is deprecated and only meant
for helping comptability in the interim.

430c8606e9 Added osg::EarthSky node to the core osg library, and added support for it into
osgUtil::SceneView, osg::CullVisitor, osgPlugin/osg and updated the hangglide
demo to use the new earth sky node.

fc1fa57275 Added support for osg::StateSet comparison operators and using this new feature
added support in osgUtil::OptimizeStateVisitor for removing duplicate
StateSet's from the scene graph, previously only duplicated StateAttributes
we're removed.

736e0f73c3 o Added osgUtil::StateOptimizeVisitor which traversing the scene
graph and builds up a map of all StateAttributes and StateSets
    and then removes the duplicates. This promotes state sharing
    throughout the scene graph which inturn can significantly improve
    performance thanks to reduced state changing. Particularily
    effective on datasets where a great deal of duplicated state
exists.
  o Added pure virtual compare(const osg::StateAttribute&)
    method to osg::StateAttribute, and implemented it in all the
    subclasses from StateAttribute. Added <,== & != operator
    on StateAttribute and Matrix to support new StateOptimizeVisitor.
  o Added META_Object, META_Node and META_StateAttribute macros to
    Object, Node and StateAttribute respectively which define the
    standard pure virtual methods such as clone, className
    & isSameKindAs.  Changed all the appropriate header files to
    use these macro's rather define them in each header, these cleans
    up the headers considerably.
  o Corrected the implementation of osg::Light::getType so it correctly
    uses a unique type for each of the OpenGL lights (GL_LIGHT0..
    GL_LIGHT7 relates to osg::StateAttriburte::LIGHT_0..LIGHT_7.
  o Changed the definition of osg::StateStateAttribute::Type to
    is now a unsigned int rather than an enum, and have changed the
    name of the previous Type enum list to be Types.  This makes it
    more consistent with the difination of values found in
StateAttribute
    and also easier to extend with having to cast to an enum.
  o From Pail Fredrikson, updated Maitrx.new implemention which uses
    the same matrix orientation as the original Matrix implemention.

81f553aaee o Updated Metrowerks files for MacOS. They aren't 100% there yet,
but getting there.

  o First cut of osgcluster demo.  Very simple beginings.  Alas
    I only one PC here so I can't test it in its current guise.

  o New support for NodeCallbacks, via AppCallback attached to
    osg::Node's, and a default osgUtil::AppVisitor which calls them on
    each frame.

  o Support for traversal masks in osg::NodeVisitor, osg::Node
    which allows nodes to be switched on or off via a bit mask.

  o Suppport for traversal number (frame number) and reference time
    into osg::NodeVisitor to handle syncronization of app and cull
    traversals.  This also assist clustering as traversal number
    master to slaves.
