Can anyone tell me what the issue actually is?

Conform does things like turn on stipple but set an all-ones pattern to ensure that triangle rasterization is invarient over such noops.


I can no longer remember exactly how the g400 was failing to pass this test.

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.
