[Mesa-dev] [PATCH] i965: Use sample barycentric coordinates with per sample shading

[Chris Forbes]

I would have expected explicit qualifiers to trump everything. I
wonder why that was removed -- Ian?

It seems there's a clear precedent established by the other drivers,
though -- so I think we should stick to it.

Bonus for us: since our centroid support is a bit bogus and requires
workarounds, we get to emit slightly better code this way :)
