--- Comment #1 from Jason Ekstrand <jason at jlekstrand.net> ---
Did a little digging tonight with Ken.  The mix test fails all seem to be
because of some imprecision in LRP.  Ken found some documentation that
indicates it may have something to do with the fact that the destination is an
MRF.  The cube tests are all because we are failing to set the "Base Mip Level"
parameter in SAMPLER_STATE.  It turns out we've been failing to set this since
the dawn of time but we've never noticed until now.  I've got a patch that I'll
send once Jenkins is done with it.
