06fcbe0092 Don't add clearcoat BRDF to specular light as-is.
BRDF needs to be multiplied with N.L, the incoming light and attenuation. Also specular_blob_intensity should affect clearcoat.

cb0bf1edea Rename Schlick GGX to GGX.
Schlick's approximation and GGX are orthogonal concepts.

Furthermore, it's usage so far has been inconsistent: we don't even use it with anisotropic SchlickGGX, and Burley (Disney) diffuse does use it while its name doesn't indicate it.

The use of Schlick's approximation in Burley and GGX is an implementation detail and doesn't need to be reflected to the namig.

This one allows for complex shaders paired with a simple lighting shader to skip code that would otherwise be pointlessly (and wastefully) run during the light pass.
