GRIM: Correct diffuse reflectance.

Browse source 
Determined by keping a single directional light source enabled, as they are
not subject to attenuation (having no position), and comparing with
original software renderer.
Default DirectX material reflects all diffuse light, so 1.0f coefficient is
likely correct.
