Unless it's significantly faster for you than for me, we need the speed to
come from somewhere. I believe we can  save varyings by computing things
as uniforms - hazeColor for instance actually is a uniform, I just don't
know how to compute it outside the shader and pass it. The whole relative
geometry between sun and eye is uniform.
