fix(shaders): the highlight of the sun is multiplied by the cosine of its light, so surfaces no longer glare milky white under a low sun; headlights light a surface with 1.35 of its diffuse colour and add a GGX highlight of their own scaled by specgloss and param_specular instead of multiplying the whole light by one plus param_specular; normalmap, parallax, detail, shadowless, sunless and default_detail materials read param_glossiness as a Phong exponent, roughness = (2 / (n + 2))^1/4, instead of 1 - 1/n or a fixed mirror
