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().
CID 11677: Uninitialized scalar field (UNINIT_CTOR)
Non-static class member _minimumNumberAccumAlphaBits is not initialized in this constructor nor in any functions that it calls.
Non-static class member _minimumNumberAccumBlueBits is not initialized in this constructor nor in any functions that it calls.
Non-static class member _minimumNumberAccumGreenBits is not initialized in this constructor nor in any functions that it calls.
Non-static class member _minimumNumberAccumRedBits is not initialized in this constructor nor in any functions that it calls.
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.
Therefore I have changed all the occurances of atof by asciiToFloat or
asciiToDouble.
I believe that it is safe to do so at least for all the plugins.
Included here are also asciiToFloat conversion of environment variables. One
might argue that these should be locale dependent. But IMO these should be
set and interpreted by osg independent of the current locale.
