This one is my fault. Due to a preprocessing mishap, the values for the
surface albedo and specular values were being set to (0.0, 0.0, 0.0).
The compiler correctly spotted that I was multiplying the light values
by this constant zero value later on and optimized out the light values
entirely.

Sorry for the noise!
