3e0435febd From Jannik Heller , GL object deletion fix. 
"This submission changes deleteGLObject calls to scheduleGLObjectForDeletion, to ensure that the actual deletion happens from the correct thread (the graphics thread). This fixes the leak I reported in http://forum.openscenegraph.org/viewtopic.php?t=15567 , and possibly also http://forum.openscenegraph.org/viewtopic.php?t=15564."

161246d864 Refactored the GL object deletion management to use new osg::GraphicsObjectManager/GLObjectManager base classes, and osg::ContextData container. 
This approach unifies much of the code handling the clean up of OpenGL graphics data, avoids lots of local mutexes and static variables that were previously required,
and enables the clean up scheme to be easily extended by users providing their own GraphicsObjectManager subclasses.

b90503fdf5 Introduced new shader composition approach that utilizes #pragma requires(), #pragma import_defines() and #ifdef in GLSL to enable multiple different versions of shaders based 
on defines passed in from osg::StateSet::setDefine(..).

26a8f63212 From Wang Rui, "In the attached files I've added the Compute Shader support for OSG, as well as serializer updates and a new osgcomputeshaders example. My submission also include a setComputeGroups() function in Program for setting compute-shader work groups, and a bindToImageUnit() function in Texture for binding textures as image variables in shaders. 
All code are tested on Windows 7 + NVIDIA GFX 570 with the latest GeForce 310.70 Driver (BETA), which could support OpenGL 4.3.

Compute shader information can be found at "http://www.opengl.org/registry/specs/ARB/compute_shader.txt"

54afbb9ff8 From Jahannes Bauerle, "l discovered that the shader class(/src/osg/Shader.cpp) shows wrong behavior when using binary shaders . When shader objects are compared the reference pointer behind the _shaderBinary member is not included in the comparison. 
I included binary shaders into an osgt model file. These shaders only consists of the binary shader code, I did not supply the text version additionally. When loading the model  the osg::Optimizer threw away all shaders except the first one. In the current trunk version of the file two shader objects are identical despite differing _shaderBinary members as the compare method of the Shader class does not include the comparison of that member.

The fix in this submission adds the check for identity of the referenced binary shaders to the shader class.

When comparing two shader objects with text source shaders the new lines of comparison are not even executed as the comparison returns false in the previous lines when the text shaders differ.

With this fix I get expected behavior, the Optimizer handles the different shaders correctly."

2d28026654 From David Fries, "Fix remote X11 crash querying GL_NUM_EXTENSIONS 
In osg::isGLExtensionOrVersionSupported in src/osg/GLExtensions.cpp when
using indirect X11 rendering,
glGetIntegerv( GL_NUM_EXTENSIONS, &numExt );
is leaving numExt uninitilized causing the following glGetStringi to
return NULL when the extension number isn't present.  Passing NULL to
std::string() then crashes.  This is with the following nVidia driver.
OpenGL version string: 3.3.0 NVIDIA 256.35

I went ahead and initialized some of the other variables before
glGetInitegerv in other files as well.  I don't know for sure
which ones can fail, so I don't know which are strictly required.
