  /*
    Light colors will be multiplied by material colors. Light can't really be transparent,
    so we'll use alpha to represent intensity. This means we must multiply resultant light
    colors by light alpha, and then hard-code alpha 1 to avoid polluting transparency.
    
    The reason we use LIGHT_*.a instead of _*.a is because _*.a has been tainted by attenuation.
    A light's intensity, regardless of distance or relative brightness, has not actually changed;
    attenuation has been factored into color already; we don't want to square the atten amt.
