[Nouveau] [RFC PATCH 00/11] Implement ARB_cull_distance

[Tobias Klausmann]

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 UsesClipCullDistanceOut
  gallium: add support for arb_cull_distance
  nouveau/codegen: sort in galliums cull_distance semantic into the
    drivers bitmask
  nouveau/nvc0: implement cull_distance as a special form of clip
    distance
