This patch series adds the needed support for this extension to the various parts of mesa to finally enable it for nvc0. Dave Airlie (1): glsl: lower cull_distance into cull_distance_mesa Tobias Klausmann (10): glapi: add GL_ARB_cull_distance mesa/main: add support for GL_ARB_cull_distance mesa/prog: Add varyings for arb_cull_distance mesa/st: add support for GL_ARB_cull_distance glsl: Add a helper to see if an array was unsize in the shader glsl: Add arb_cull_distance support i965: rename UsesClipDistanceOut to UsesClipCull...
