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"
