The short description is "Implementation of the
ARB_tessellation_shader extension in Mesa This includes * Piglit tests
* Mesa front-end implementation * GLSL compiler support for two new
shader targets * driver back-end implementation"

The backend implementation is for IvyBridge. I'm not sure if I'm
allowed or should post more of the proposal.

But, I'm not sure what point you're making?
