b09052002c Eevee: Add support for volumetrics in node tree. 
Only volume scatter is implemented for now.

2eef097831 GPU Codegen: Add new closure socket type. 
This allow specialized shaders to redefine the closure interface to fit their needs.

For instance, Volumetric closure needs to pass more than one vec4 (absorption vec3, scattering vec3, anisotropy float).

a1a40bfe70 GPUTexture : Un-clamp float rect datas. 
We do not need it anymore because we do not use glu anymore. And we need full range for HDRI Lighting.

87dd9c31a0 GPU: split GPU_material_from_nodetree in two 
Add GPU_material_from_nodetree_find to avoid having to construct other
arguments which won't be used in the case the material is exists.

0394c04a7f Eevee: Add Planar reflection blurring. 
This method is very cheap and inaccurate. This will fill the gap untill better model is supported.

6f0b80425b Fix shaders not working in Eevee 
Not a single node based shader was working since a recent merge from
master.

The merge brought changes from the principle bsdf shader where
unsupported gl_ProjectionMatrix was still being used.

779c950098 Eevee: Ambient Occlusion: Initial implementation. 
Implement GTAO (Ground Truth Ambient Occlusion) which is a special case of Horizon Based Ambient Occlusion that is more physically accurate.
Also add a bent normal option to sample indirect irradiance (diffuse lighting) with the least occluded direction.

ed59d03bfc GPUFramebuffer: Add recursive downsampling function. 
This special case function enables rendering to a miplevel while using the miplevels above as texture input.
This is needed for some algorithm (i.e. creating a min-max depth pyramid texture).

14ea0c5fcc Fix T51849: change Cycles clearcoat gloss to roughness. 
This is compatible with UE4 and more consistent with specular and transmission
roughness, even if it deviates from the original Disney BRDF.

5c5c09439a Clean node names and organize menus for eevee 
This makes the node menus aware of the Cycles/Eevee distinction, and
only show the relevant nodes for the current engine. Names have also
been changed to accomodate for the new output node system.

aaf37e1216 Implement Eevee output node system 
This makes Eevee consistent with Cycles, by having a single output node,
and multiple shader nodes that connect to it.

Note that node systems for Eevee saved before this will be missing the
output node, and thus will show an invalid material. This is easily
resolved by connecting the shader output to a new output node.

f2cc6c9254 TexFace removal part 2 
- Derived-mesh drawing.
- All non UV members of TexFace structs.

MTexPoly is now redundant but keeping with a dummy member,
will check on complete removal later.

7a9ad029dd Remove TexFace, per-face images 
TexFace complicates the now more popular shading pipeline by having
per-face images, see: T51382 for details.

To keep the ability to select a per-material edit-image
(used with UV-mapping workflow), the material now stores an image
which will be set when changing images in edit-mode.

This is used as a bake-target when not using Cycles too.
