341ffb2361 Further work on cleaning up SceneView and Camera, in particular moving strereo
support out of Camera and into SceneView. Also enabled the option to set the
projection and modelview matrices directly on SceneView thereby removing the
dependance on osg::Camrea to control the view of the scene.

360247225e Added new osg::DrawPixels class with encapsulates glDrawPixels as and
osg::Drawable.  Added osg::Image::readPixels to osg::Image.

Made osg::LightSource to default to cullActive set to false to that LightSource
nodes don't get culled by default.

6f65e86057 Further work on removing Camera references from NewCullVisitor and releted
classes, this work paves the way for making osg::Camera an optional
extra rather than a requirement for rendering.

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.

56cee8c711 Move the applying of Projection and ModelView matrices into osg::State so that
it now maintains references to the last applied matrices, automatically doing
lazy state updating.  This simplifies the various places in the OSG which
were previously doing the applying, add paves the way for managing the
projection matrix within the scene graph.

Remove MemoryAdapter and mem_ptr as they arn't being used, and can potentially
confuse users by their existance.

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.

b53b3038eb _cullMaskRight was not being initialized in the constructor which was
resulting in some sporadic problems when running stereo - occoasionally the
right eye view wouldn't appear!

c49c62ee15 Integrated various changes worked on at the Glasgow Science Center. Changes
include change the CameraManipulators so they work with double for time
instead of float.  Also added support for DataType to osg::StateAttribute
and StateSet so that they can be set to either STATIC or DYNAMIC, this
allows the optimizer to know whether that an attribute can be optimized
or not.

a6aa57a255 Added support for seperate traversal masks for standard, left and right
cull traversals.  This allows one to create seperate rendering for left
and right eyes when doing stereo.

386b87d4a0 Cleand up the root Makefile.
Moved CullVisitor/RenderStage/RenderStageLighting across to managing lights
entirely within RenderStageLighting, and changed the management of modelview
matrices so that RenderLeaf now stores the absolute modelview matrix, rather
than a model matrix as done previously. The later allows RenderLeaf's to do
a glLoadMatrix rather than a glPushMatrix/glMultMatrix/glPopMatrix.

d9398af300 Fixed a bug in the drive manipulator which was due to it using the local
coords of the intersection point with the scene rather than the world
coord value for that point.  The code now uses
osgUtil::Hit::getWorldIntersectionPoint() method for getting the world coords.

Added support for getWorldIntersectionPoint to Viewer.cpp.

Put and #ifdef around the setting of the default display list visitor so
it nolonger sets in under IRIX. This is a world around to the IR graphics
imbending lighting info into display lists, if the display lists are
created before state is set up it produces lighting artifacts such as
flickering.  Remove the the default display list init visitor removes
these problems, display lists are then built on the fly and drawables
a drawn for the first time.

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.

98c8447ae9 Fixed the osg::Light so that it requires the user to explicitly define which
OpenGL light is being operated on, and also now relies upong the standard
osg::State handling of OpenGL modes to switch on the appropriate lights.

The previous static counter mechansim for the light number was causing a
redundent light to be created when the osg plugin created the first osg::Light
to use a prototype for other osg::Light's to be cloned from in the
.osg plugin execution.

The static count mechanism also prevent the lights modes being controlled
independantly from the setting of the light paramters themselves.  This
meant that a light once created was global, and couldn't be turned off
locally via the OSG's support for OpenGL mode enabling/disabling.  This
has been overcome with the new implementation, the user has complete
flexiblity of when and where to use the different lights at their
disposal.

19c99dc94c Further work on improving stereo support in the OSG.
Renamed the osg::VisualsSettings to osg::DisplaySettings, and
osgUtil::VisualsRequirementsVisitor to osgUtil::DisplayRequirementsVisitor.

Added support for OSG_SCREEN_HEIGHT into osg::DisplaySettings, and added
a DisplaySettings* to the constructors of osg::SceneView and osg::Camera.

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.
