The only issue I found with glean right now is that hw.blend_func isn't properly initialized and if an app calls glBlendFunc( GL_ONE, GL_ZERO ); the actual function will be GL_ZERO,GL_ZERO. This caused the BlendFunc test to fail unless polygon stipple was enabled...
It's possible that this might have been the actual cause of the conformance problem, and what we did just worked around it.
I only had a quick look at the old code. It was somewhat different looking but it's certainly possible that the same bug was present.
But since there's no stipple on/off bit then tests with stipple disable should fail too if all ones stipple fails. Maybe the tests touched BlendFunc somewhere so that the bug only showed itself with all ones stipple...
Unless someone objects I'll re-enable the all ones pattern (and fix the bug with BlendFunc).
No objection here.
