The GE normalizes with its own reciprocal square root, a 2 x 128 segment table like its reciprocal's (measured on gpu/probe exp69), and sums dot products and the world matrix rows like clip space rows. Used for normals, light vectors, the half vector, the normalized normal texgen source, and the world position. Bit exact on exp61, exp64 and exp69; point light attenuation is 99.9%.

To get to 100% compatibility, we will need a software renderer as there are games out there that do tricks that can't really be faked in a sensible way. Useful for homebrew too that mix sw and accel rendering.
