...perhaps other hw has them totally separate, > dunno. With my limited experience about other hardware i'd go with seperate clip/cull and let the drivers figure out the right way to place them. That gives us the freedom to have it the way nv50/nvc0 works and other ways, like seperated clip/cull_distances if needed. Maybe we should just consider nouveau and radeon and decide by the hw of these often used drivers.

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...
