Hmm, I see your point. Fractional values don't have a lot of meaning in the views, but without a fraction from somewhere we don't capture all of GL semantics. I guess this is the underlying reason GL has such a wide variety of ways of specifying the min/max level also. And finally, it seems like DX10 has done the same thing - with both integer min/max in views and float min/max in the sampler state. It looks like we really do want to keep them both.
