For clang-format not to wrap definitions.

Needed for clang formatting to workaround bug/limit, see: T53211

Also contains some code typo fixes (mostly, adtaptative -> adaptive,
former is nearly innexistant in English, let's stick to simple valid
words ;) ).

Object visibility is now handled by the depsgraph iterator, but this API
was incomplete as it made no distinction for visibility of the object itself,
particles and generated instances.
The depsgraph iterator API now includes information about which part of the
object is visible, and this is used by Cycles to replace the old custom logic.
Cycles and EEVEE visibility should now be consistent, which unfortunately does
means some subtle compatibility breakage for both.
Fixes T58956, T58202, T59284.

There were at least three copies of those:
- OB_RECALC* family of flags, which are rudiment of an old
dependency graph system.
- PSYS_RECALC* which were used by old dependency graph system
as a separate set since the graph itself did not handle
particle systems.
- DEG_TAG_* which was used to tag IDs.
Now there is a single set, which defines what can be tagged
and queried for an update. It also has some aggregate flags
to make queries simpler.
Lets once and for all solve the madness of those flags, stick
to a single set, which will not overlap with anything or require
any extra conversion.
Technically, shouldn't be measurable user difference, but some
of the agregate flags for few dependency graph components did
change.

This setting can be tweaked to improve glossy reflection cubemaps.
It increases the sample count for each roughness level.
This settings affect the lookdev mode quality as well.
|
|
This enables reducing the noise comming from very bright light sources
(like a sun) that can be found in distant HDRIs.
The lost energy may be replaced manually by a sunlight that compensate the
this loss.
This clamping only concerns Reflection Cubmaps and is done on all on all
of them.
Setting to 0.0 disables it (default).

This is a parameter that will make the interpolation between irradiance
cells of a same Irradiance Volume smoother, reducing the weight of the
light leaking correction factors.
It is usefull in some cases to avoid harsh lighting transition that can
happen when a sample point it near a surface.

This makes it possible to tweak indirect lighting in the shader.
Only a subset of the outputs is supported and the ray depth has not exactly
the same meaning:
Is Camera : Supported.
Is Shadow : Supported.
Is Diffuse : Supported.
Is Glossy : Supported.
Is Singular : Not supported. Same as Is Glossy.
Is Reflection : Not supported. Same as Is Glossy.
Is Transmission : Not supported. Same as Is Glossy.
Ray Length : Not supported. Defaults to 1.0.
Ray Depth : Indicate the current bounce when baking the light cache.
Diffuse Depth : Same as Ray Depth but only when baking diffuse light.
Glossy Depth : Same as Ray Depth but only when baking specular light.
Transparent Depth : Not supported. Defaults to 0.
Transmission Depth : Not supported. Same as Glossy Depth.
Caveat: Is Glossy does not work with Screen Space Reflections but does work
with reflection planes (when used with SSR or not).
We have to render the world twice for that to work.

This was caused by some threading conflict.

This new option is located in the shadows options in the render settings.
This approach is simple and just randomize the shadow map position (not
the lamp itself) and just let the temporal supersampling do the average of
all the shadowing. The downside is that is needs quite a large number of
samples to give smooth results and individual sample position can remain
visible.
Enabling this option will make the viewport refresh all shadow maps every
redraw so it has a serious performance impact.
This approach is not physicaly based at all and will not match cycles.

Was caused by a threading issue. The lightcache was free before the endjob
function pass it to the scene.
Also fix cache reuse if size matches.

Was caused by the normal pass being enbaled in the renderlayer settings.

This does not include all the struct and type renaming. Only files were
renamed.
gwn_batch.c/h was fusioned with GPU_batch.c/h
gwn_immediate.c/h was fusioned with GPU_immediate.c/h
gwn_imm_util.c/h was fusioned with GPU_immediate_util.c/h

This separate probe rendering from viewport rendering, making possible to
run the baking in another thread (non blocking and faster).
The baked lighting is saved in the blend file. Nothing needs to be
recomputed on load.
There is a few missing bits / bugs:
- Cache cannot be saved to disk as a separate file, it is saved in the DNA
for now making file larger and memory usage higher.
- Auto update only cubemaps does update the grids (bug).
- Probes cannot be updated individually (considered as dynamic).
- Light Cache cannot be (re)generated during render.
