We have a limited number of interpolants, and 2 were used for spotlights, but this is a fairly uncommon case, so we move the calculation to the fragment shader. A side effect of this is that we are not limited to two spot-light anymore from the shader's point of view. This essentially adds a vector transform per fragment, but on the other hand, it removes communication between the vertex and fragment shader, as well as interpolation of the position.
