[Mesa-dev] [PATCH V2 00/12] i965: gl_ClipDistance support for Gen4/5.

[Chris Forbes]

This series adds support for GLSL-1.30 clip distances on Gen4/5, and
extends max clip planes to match the 1.30 requirement on Cantiga and later.

Passes 2000/2004 glsl-1.30 piglits on Ironlake. The missing 4 tests here are
bugs in handling unusual `switch` control flow, and affect all gens.

Passes 1975/2004 glsl-1.30 piglits on Cantiga.

I would appreciate someone testing this on original Gen4, to ensure
that I haven't regressed anything there.
