spotLightCone
Define a spot light's angular falloff via inner and outer cones (half-angles in radians). Both angles are clamped to 0.00873, π/2 to avoid precision issues. Ignored for directional and point lights. For Type.FOCUSED_SPOT (physically correct), outer cone angle affects total illumination. For Type.SPOT, outer cone and illumination are decoupled (easier to tweak).
