i.e. there's some bug with the OpenCL renders in Full lighting model (i.e.
when 'lightmodel' is 0). It shows up when you try to render ehy in the
default view and lightmodel.
I had to port code over from liboptical and librt to get Full lighting
model up so there might be something slightly off. I ported over the Phong
materials (default) but there might be a bug somewhere.
