anisotropic rotations

Improvement of the SSS in the Disney shader

* Now the bump normal is correctly used for the SSS.
* SSS in Disney uses the Disney diffuse shader

Better calculation of the Disney diffuse part

Now the values for NdotL und NdotV are clamped to 0.0f for a better look
when using normal maps

Now one can disable specular reflactions again by setting specular and
metallic to 0 (cracked this in the previous commit)

Rollback attempt to fix sss crashing, it prevented crash by disabling sss completely, thus useless

Attempt to fix Disney SSS

commit dbad91ca6d46f5a4a6f2ba7ed4c811ffa723942f
Author: Pascal Schoen <[email protected]>
Date: Wed Jul 20 11:13:00 2016 +0200

Added a roughness parameter for refractions (for scattering of the rays
within an object)

With this, one can create a translucent material with a smooth surface and
with a milky look.

The final refraction roughness has to be calculated using the surface
roughness and the refraction roughness because those two are correlated
for refractions. If a ray hits a rough surface of a translucent material,
it is scattered while entering the surface. Then it is scattered further
within the object. The calculation I'm using is the following:

RefrRoughnessFinal = 1.0 - (1.0 - Roughness) * (1.0 - RefrRoughness)

Author: Pascal Schoen <[email protected]>
Date: Tue May 31 11:18:07 2016 +0200

Added parameters IOR and Transparency for refractions

With this, the Disney BRDF/BSSRDF is extended by the BTDF part.

Author: Pascal Schoen <[email protected]>
Date: Mon May 30 15:08:18 2016 +0200

Added an additional normal for the clearcoat

With this normal one can simulate a thin layer of clearcoat by applying a
smoother normal map than the original to this input

SVM and OSL are both working for the simple version of the Disney BRDF

Disney node can be used without SVM and started to cleanup the OSL implementation

There is still some wrong behavior for SVM for the Schlick Fresnel part at the
specular and clearcoat

added output parameter to the DisneyBsdfNode

That has been forgotten after removing the inheritance of BsdfNode

commit f91a28639884cbda7804715b910d64abba0718ef
Author: Pascal Schoen <[email protected]>
Date: Tue May 17 10:40:48 2016 +0200

removed BsdfNode class inheritance for DisneyBsdfNode

That's due to a naming difference. The Disney BSDF uses the name 'Base Color'
while the BsdfNode had a 'Color' input. That caused a text message to be
printed while rendering.
