Latest push updates the test to fall in line with the others in sampler.shader_test - like SampleBias it mostly just checks to make sure that it properly recognizes the function signature, and otherwise produces a result similar to plain Sample(). Porting over the full d3d12 test ended up being a pretty beefy task since it does a per-pixel test with mips, so I fell back to what the HLSL tests were already doing and will let the d3d12 test do the hard work :sweat_smile:
