85f1b7358a Eevee: Planar Reflection: Remove distance approximation. 
This commit separate the depth texture into another texture array.
This remove the need to output radial depth into alpha.
Unfortunatly it's difficult to recover position from the non linear depth buffer when applying reflection without adding a bunch of stuff.
This is in preparation of SSR planar reflections.

c5f4342692 Eevee: SSR: Small fixes 
- Encode normals for other opaque bsdf so they are not rejected by the normal facing test.
- Early out non reflective surfaces.
- Add small offset to raytrace to avoid self intersection.
- Fix fallback probes not appearing.

1d00a66f5d Eevee: SSR: Encode Normal in buffer and add cubemap fallback. 
Normals can point away from the camera so we cannot just put XY in the buffer and reconstruct Z later as we would not know the sign of Z.

2a84331f02 Eevee: SSR: Output ssr datas to buffers. 
Output in 2 buffers Normals, Specular Color and roughness.
This way we can raytrace in a defered fashion and blend the exact contribution of the specular lobe on top of the opaque pass.

An id is given to each glossy node in order to determine which specular lobe is using ssr.

d35c24f87b Eevee: Transparency: Add support for blend ADD and MULTIPLY. 
This introduces a new transparency pass.
It bypass the radial distance encoding in alpha for the transparent shaders.

05bef13b53 Eevee: Add support for Alpha clip and Hashed Alpha transparency. 
Hashed Alpha transparency offers a noisy output but has the benefit of being correctly ordered. Noise can be attenuated with Multisampling / AntiAliasing.

Also Use World normal instead of view normal as input.

This enables texturing of the noise via procedural or baked textures.
Note that it gets quickly really heavy.

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).

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.

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.

8d7b98bfd3 OpenGL: cleanup material shader GLSL 
prefer vector math over scalar
prefer * over /
shorten vec3(x, x, x) to vec3(x)
use clamp, max, etc. instead of custom logic
declare loop vars as part of for loop
spacing
