68f37c4dcb From Tim More and Robert Osfield, implementation of ARB_timer_query based GPU timing stats syncronization. 
Initial email from Tim : "I've implemented using a timestamp, available with ARB_timer_query and OpenGL 3.3, to gather GPU stats. This is nice because it can accurately fix the GPU draw time with respect to the other times on the stats graph, rather than having to estimate the wall time of the end of GPU drawing. This also prevents anomalies like the GPU phase starting before the draw phase..."
Changes to Tim's submission by Robert:  Removal of need for swap buffer callback in ViewerBase.cpp, by
integrating a osg::State::frameCompleted() method that does the stats timing collection.  Introduction of a
GraphicsContext::swapBuffersCallbackOrImplementation() method that calls the State::frameCompleted() and
the swap buffers callback or the swapImplementation as required.

327b67a305 Added CMake support for specifying what OpenGL target and features that the OpenSceneGraph build should use. 
Added use of the new Cmake generated #define's for optionally compiling parts of the OpenSceneGraph's OpenGL support for the various OpenGL targets

6a56b6e6be Refactored osg::Geometry::drawImplementation(..) to use new osg::ArrayDispatchers that encapsulate the task 
of dispatch osg::Array data as OpenGL attributes.

ef1c9d9e3c From David Fries, "The Extensions object was calling _gl_get_query_objectui64v but 
checking _gl_get_query_objectuiv_arb which is a different function
pointer.  Changed to check the function being called.

This is against the subversion trunk."

c58ff9b656 From Lionel Lagarde, "The copy constructor of the nodes and the drawables do : 
Node::Node(Node &node, copyop) :
  _stateSet(copyop(node.getStateSet()),

It doesn't call the setStateSet method of osg::Node (or osg::Drawable). So the parent
list of the state set is not updated with the new node (drawable)."

ff565128af Introduced new osg::discardDeletedOpenGLObjects() methods, and usage of it in 
GrpahicsContext::close() to handle cases where deletingOpenGLObjects is no possible,
such as when GraphicsWindowEmbedded is used.

409cdd0b28 Intoduced a new setGLExtensions template method to do a copy of void* pointer to 
local function pointer to avoid compiler warnings related to case void*.

Moved various OSG classes across to using setGLExtensions instead of getGLExtensions,
and changed them to use typedef declarations in the headers rather than casts in
the .cpp.

eac3dc1963 From Paul Melis, "Here is a list of fixes to misspelled APIs. Unfortunately, more than one 
of these are public APIs and therefore will break linkage to existing
shared libraries."

d1a1b1d95c Added more comprehensive releaseGLObjects(State*=0) throughout Nodes, 
Drawables,StateSet, and osgDB::Registry.

Added cleanup_frame() from to osgProducer::OsgCamerGroup to help with proper

a1bda0dab8 Added support for per context extension string. 
Note, this required adding a unsigned int context ID to the osg::isGLUExtensionSupported(,)
and osg::isGLExtensionSupported(,) functions.  This may require reimplementation
of end user code to accomodate the new calling convention.
