[Mesa-dev] [PATCH v2] r600g: Implement GL_ARB_sample_shading

Tested with v3. I get the same result as before: everything is fine 
except the gs-atan-vec2 test.

I don't know if this is of any value, but running the command manually 
in a shell gives the following: 
PIGLIT: {"result": "pass" }

I assume the test ran correctly, but not in the context of the piglit 
run, am I right?
