Gallium3D Softpipe Hits GLSL 3.30 Compliance

The Gallium3D "Softpipe" driver as the most crude software fallback driver now supports GL Shading Language 3.30.

Dave Airlie of Red Hat sent in a number of Softpipe-related commits on Tuesday. This work surrounds the Softpipe driver that is used in non-hardware-GPU, software-fallback purposes beyond LLVMpipe that at least leverages LLVM for greater CPU acceleration abilities.

For a while now, LLVMpipe has supported OpenGL 3.3 fully beyond just the GL Shading Language requirements, while now the more basic Softpipe is catching up, per recent commits that will ultimately be found in Mesa 10.3.
