Directional Light has "sides" #98
Description
This might be the same issue as #61, which is for top/bottom, but I'm not sure.
When creating a directional light (pointing downwards), if you pan the camera far enough to the left or right, you get darkness. I'm working around this for now by periodically dirtying all the static lights, but that's sorta ugly.
Is this expected? Am I supposed to poke static lights periodically, or should they "know" that the camera is panning near/past the last calculated light area?
