Point shadows + falloff

Should this be an enum like pc.scene.LIGHTTYPE_*? Personally, I'm starting to dislike this style of enum. It's very C++-like. I'd kind of prefer to use strings. e.g. light.setType('point'); instead of light.setType(pc.scene.LIGHTTYPE_POINT); The problem is, there's already an existing style of enums and we have to be mindful of that. :(
