I'm trying to say that we can just implement tex1D(s, coords) as if it were tex2D(s, float2(coords.x, 0.5)) in the intrinsic handler. Similarly tex1Dproj(s, coords) can be tex2Dproj(s, float4(coords.x, 0.5, 0, coords.w)). The only potential difference is that native throws different garbage into the y coordinate, depending on shader target, but I'm not really sure that it matters.
