Fixed-function GL differentiates point and directional lights with the w of the position. Is there a branchless way to do that in a shader?

@warrenm I just realized I can do better. A directional light is just a point light whose position varies depending on where it's measured.
@CastIrony I’m concerned about implementing falloff with this approach, but it’s ripe for further thought. Thanks for the suggestions!
