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.

Form Richard Schmidt, "The following features were added:
...
* the glsl plugin now supports processing #includes. The file extension sets the shader type.
* the registry releases gl objects of the shared state manager

From Stephane Lamoliatte, "Here is a patch wich improves the support for geometry shaders in OpenSceneGraph.
...
It adds new PrimitiveSet constants for the specific geometry shader primitive types :
- LINES_ADJACENCY
- LINE_STRIP_ADJACENCY
- TRIANGLES_ADJACENCY
- TRIANGLE_STRIP_ADJACENCY
It also adds some missing features to the glsl reader plug'in.

From Bryan Thrall, "The attached ReaderWriterGLSL.cpp conveniently sets the shader type when
...
the filename extension is "vert" or "frag" but still lets this be
overridden by the Options (for those crazy people who store their
fragment shaders in .vert files :) )."
