Added OSG_VERTEX_BUFFER_HINT env var to osg::DisplaySettings with VERTEX_BUFFER_OBJECT/VBO, VERTEX_ARRAY_OBJECT/VAO and NO_PREFERENCE to allow one to foce on VBO or VAO usage.
Restructred BufferObject assigned in osg::Geometry
Added
To enable the sync of swap buffers set the env var OSG_SYNC_SWAP_BUFFERS to ON or 1, to switch off set to OFF or 0.
One can also use the --sync command line option for application that pass on command line options to the osg::DisplaySettings::instance().

Added new WindowSystemInterface::setDisplaySettings() method to provide a mechanism for passing settings onto the WindowSystemInterface so it can then set up the system appropriately.
Added assignment of the DisplaySettings to the WindowSystemInterface in Viewer/ComppsiteViewer::realize().
DisplaySettings now define COLOR and DEPTH as defaults for implicit buffers. Consequently Camera by default uses the same defaults through USE_DISPLAY_SETTINGS_MASK. However, particular Camera mask can be easily overriden through Camera::setImplicitBufferAttachmentMask method. I hope, that in this way we can have global control over implicit buffer defaults, and we can still retain fine grained control at Camera level.
I have also replaced original unsigned ints used to store masks to signed ints because complier resolves enums as signed integer (I got a number of warnings with unsigned int)."
Moved the handling of DisplaySettings into Traits constructor.
Added support for s/getGLContextVersion(), s/getGLContextFlags() and s/getGLContextProfileMask() to osg::DisplaySettings.
Added command line and env var support for setting the GLContextVersion, GLContextFlags and GLContextProfileMask to osg::DisplaySettings.
stereo format to work. It's a good thing I tested these on a TV
before submitting them since I did indeed have a bug. One thing I
did not test was to see how this would work in windowed mode. Does
the interlaced stereo code have support for 'absolute' positions?
For example a given pixel on the screen is always shown in a given
eye no matter where the graphics context is placed?
"
osg::DisplaySettings class. OsgCameraGroup will now read the setting
from the DisplaySettings instead of hardcoding the value. I added the
following commandline option to be able to set the multisample value:
--samples <num>
One thing to note, OsgCameraGroup would previously check if the
computer is an SGI and set multisample to 4. I retained this check in
DisplaySettings to be backwards compatible."
to and command line arguments to set it.
Added support for using the DisplaySettings::getDisplayType() to detect use
of a Head Mounted Display when doing stereo so that the asymtric frustum can
be switched off.
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.
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.
