There was a problem hiding this comment.
Using TEXTURE_MIN/MAX_LOD here works in all tests except for the unsigned integer formats (where it appears to sample from the wrong level). I'm not sure if that means there's something I don't understand, or if I've stumbled upon a bug. I'd be happy to change this code to also test the alternative way to choose which lod levels are sampled from, or to remove this (currently unreachable) branch if desired.
