Intel Sandy Bridge Picks Up transform_feedback2, Should Allow WebGL 2.0 Support

For those stuck with older Intel Sandy Bridge hardware, the integrated graphics with Mesa Git should be capable of supporting WebGL 2.0.

It's not often that Intel still contributes significant hardware-specific feature work for their much older generations of hardware like Sandy Bridge, but Kenneth Graunke today wired in ARB_transform_feedback2 for Sandy Bridge. ARB_transform_feedback2 was added to the OpenGL 4.0 specification.

By implementing ARB_transform_feedback2, Ken commented with the patch enabling it at the end of the series, "rumor has it this allows people to use WebGL 2.0 on Sandybridge."
