83a4e1aaf9 Cycles: add voronoi features and distance settings from Blender.
Features to get the 2nd, 3rd, 4th closest point instead of the closest, and
various distance metrics. No viewport/Eevee support yet.

Patch by Michel Anders, Charlie Jolly and Brecht Van Lommel.

30bffb5a3a Nodes: add sqrt, ceil, floor and fract to math nodes.
This works for Cycles, Eevee, texture nodes and compositing. It helps to
reduce the number of math nodes required in various node setups.

799779d432 Cycles: change Ambient Occlusion shader to output colors.
This means the shader can now be used for procedural texturing. New
settings on the node are Samples, Inside, Local Only and Distance.

6862762685 Cycles/Compositor: Add arctan2 operation to the Math node
The Math node currently has the normal atan() function, but for
actual angles this is fairly useless without additional nodes to handle the signs.

Since the node has two inputs anyways, it only makes sense to add an arctan2 option.

7613ffc944 Cycles: switch to squared roughness convention for all nodes.
This was already done for the Principled BSDF to be compatible with typical
baked roughness maps in PBR workflows.

b5fe00d1ac Cycles: restore Particle Info Index for now, keep it next to Random.
It seems to be useful still in cases where the particle are distributed in
a particular order or pattern, to colorize them along with that. This isn't
really well defined, but might as well avoid breaking backwards compatibility
for now.

f6107af4cf Cycles: change Index output of Hair and Particle Info to Random, in 0..1 range.
These are used for randomization, so it's convenient if the index is already
hashed and consistent with the Object Info node.

f9ea097a87 Cycles: add Vector Displacement node and extend Displacement node.
This adds midlevel and object/world space for displacement, and a
vector displacement node with tangent/object/world space, midlevel
and scale.

Note that tangent space vector displacement still is not exactly
compatible with maps created by other software, this will require
changes to the tangent computation.

b129ea843a Cycles: change material output displacement to vector.
Previously only scalar displacement along the normal was supported,
now displacement can go in any direction. For backwards compatibility,
a Displacement node will be automatically inserted in existing files.

This will make it possible to support vector displacement maps in the
future. It's already possible to use them to some extent, but requires
a manual shader node setup. For tangent space maps the right tangent
may also not be available yet, depends on the map.

26f39e6359 Cycles: add bevel shader, for raytrace based rounded edges.
The algorithm averages normals from nearby surfaces. It uses the same
sampling strategy as BSSRDFs, casting rays along the normal and two
orthogonal axes, and combining the samples with MIS.

The main concern here is that we are introducing raytracing inside
shader evaluation, which could be quite bad for GPU performance and
stack memory usage. In practice it doesn't seem so bad though.

Note that using this feature can easily slow down renders 20%, and
that if you care about performance then it's better to use a bevel
modifier. Mainly this is useful for baking, and for cases where the
mesh topology makes it difficult for the bevel modifier to work well.

commit 3cd5eb56cf
Author: Pascal Schoen <pascal_schoen@gmx.net>
Date:   Fri Sep 16 08:47:56 2016 +0200

    Fixed a bug in the Disney BSDF that caused specular reflections to be too
    bright and diffuse is now reacting to the roughness again

    - A normalization for the fresnel was missing which caused the specular
      reflections to become too bright for the single-scatter GGX
    - The roughness value for the diffuse BSSRDF part has always been
      overwritten and thus always 0
    - Also the performance for refractive materials with roughness=0.0 has
      been improved

commit 7cb37d7119
Author: Pascal Schoen <pascal_schoen@gmx.net>
Date:   Thu Sep 8 12:24:43 2016 +0200

    Added selection field to the Disney BSDF node for switching between
    "Multiscatter GGX" and "GGX"

    In the "GGX" mode there is an additional parameter for changing the
    refraction roughness for materials with smooth surfaces and rough interns
    (e.g. honey). With the "Multiscatter GGX" this effect can't be produced at
    the moment and so here will be no separation of the two roughness values.

commit dbad91ca6d
Author: Pascal Schoen <pascal_schoen@gmx.net>
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)

commit 4f955d0523
Author: Pascal Schoen <pascal_schoen@gmx.net>
Date:   Tue May 24 16:38:23 2016 +0200

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

commit 1f5c41874b
Author: Pascal Schoen <pascal_schoen@gmx.net>
Date:   Tue May 24 09:58:50 2016 +0200

    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

    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.

116bab702e Fix T47639: OpenGL render with smoke and fire incorrect when using
transparency.

The issue is that we are rendering to a 0..1 clamped sRGB buffer with
unpremultiplied alpha, where the correct thing to do would be to render
to an unclamped linear premultiplied alpha buffer. Then we would just
make fire purely emissive without affecting the alpha channel at all,
but that doesn't work here.

So for now, draw fire and smoke separately using different shaders and
blend modes, like it used to before the smoke programs were rewritten
(see rB0372b642).

e4efa16b00 Fix T48663: The Soft Light blend type layer make the color darker in the
3D view

There was a misusage of the `outcol` and `texcol` params. The actual
formula should have been:

  incol = facm * outcol + fact * ((one - outcol) * texcol * outcol +
outcol * scr);

To make sure the result is consistent with material mode, reuse the
material blend function (mix_soft), similarly to what most other texture
blend modes do.

fe44eacf78 Environment lighting for the GLSL mode
Environment lighting (aka ambient) is a key component of any renderer.
It's implemented like the Environment lighting of BI render for Approximate Gather mode. It support "Sky Color" and "White" Environment lighting modes.

It would be great if the user could see actual lighting conditions right in the Blender viewport instead of waiting for the renderer to complete the final image, exporting for external renderer or for a game engine.
