    i965: Add support for correct GL_CLAMP behavior by clamping coordinates.

    This removes the stupid strict-conformance fallback code I broke when
    adding ARB_sampler_objects.

oglc case texedge also failed due to b126a0c0cb30b1e2f2df1953fe14d8596d1cf4f7.
Comment 2 Eric Anholt 2011-05-20 13:29:23 UTC 
Can you confirm that the problem still exists before if you remove INTEL_STRICT_CONFORMANCE?  Ironlake border color handling is broken, so if you didn't have that software-fallback knob set, I expect these tests will fail beforehand as well.

(Please remove INTEL_STRICT_CONFORMANCE from testing.  We want QA to be testing the code paths that actual users experience, and as a result we're planning on just removing that environment variable since it's harmful to testing).
Comment 3 fangxun 2011-05-24 02:51:55 UTC 
If remove INTEL_STRICT_CONFORMANCE, these cases always fail.
Comment 4 Gordon Jin 2011-05-24 19:32:24 UTC 
Eric/Ian, I'm not pursuing this. Feel free to close it as wont fix.
