Alpha blended Transparency is now using dual source blending making it
fully compatible with cycles Transparent BSDF.
Multiply and additive blend mode can be achieved using some nodes and are
going to be removed.
We check if the previous iteration (sample) was using a valid double buffer.
If it wasn't, we request another iteration.
This fix the issue for viewport,viewport render and image render.

This is enabled with bl_use_eevee_viewport = True. It allows external engines
to generate an Cycles/Eevee shader node setup to emulate their materials in
the realtime viewport, or to leave it to users to do manually.
Removed bl_use_exclude_layers and bl_use_shading_nodes that did nothing
anymore. This should not break API compatibility, any scripts setting those
should continue to work the same as before.
Also adds descriptions for some RenderEngine settings.
This is too generic flag, and it might be used by anything, starting from
changes in transform ending with changes in ID properties.
The check here is to be as specific as possible. If that is not possible
the decision must be documented.

This is to simplify the usage of Volumetrics.
Now it automatically detect if there is any Volumetric material in the
view and allocate the needed buffer if any.
EEVEE assumed that the OGL renderer did FSAA, as the FSAA was removed we
needed to revalidate this assumption. The temporal sampling only inited
the matrices during init phase. As now we need to update the matrices
for every sample rendered the code for updating the matrices was
isolated in a new function `EEVEE_temporal_sampling_update_matrices`.

- Add `render_aa` and `viewport_aa` sampling setting for workbench. 0
samples means no AA, 1 sample uses FXAA and more samples will use
TAA.
The viewport `gpu_viewport_quality` can still limit viewport anti-aliasing
method.
- Use TAA when rendering images. (this used to be CPU based FSAA)
- Removed `R_OSA` related settings.

Make Lookdev works with bloom and TAA by rendering it before TAA and fixing
the motion vectors of the lookdev balls.
Rework Lookdev to remove much of its complexity. Use simpler matrices with
more understandable setup code.
Viewport now displays alpha checkerboard pattern like Cycles does when
film alpha is set to "Transparent".
Some small workarounds were necessary for Depth of Field and correct TAA
support.
* Use simple default view transform for color pickers, as Filmic does not work
well for all types of colors. We better handle this with an option and tagging
of colors as emissive or albedo like.
* For solid/workbench we also no longer use Filmic, as there is not enough contrast
and it's not really needed since this is not physically based lighting.
* For lookdev always take into account the view transform and look. Other view
settings like exposure are only taken into account if scene lighting is used,
since these are often dependent on scene light intensity.

Add 'G_draw' for all draw manager globals,

Connection between `ts` and `globals_ubo` wasn't obvious,
now called `G_draw.block` & `G_draw.block_ubo`.
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.

The crash only occurs with Intel 3rd generation GPUs.
It occurs because the program needs to be used at least once in the opengl context in which it is created.
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 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.

There was an issue caused by Antialiasing being done after DoF. Move TAA
after DOF and Motion Blur.
Also certain pixel with lower CoC would be spread all over the background
because the neighbooring pixel have higher CoC. So we need to apply some
bilateral filtering when downsampling. Currently we limit the influence of
neighbor pixels with a CoC inside the range [MaxCoC-2, MaxCoC].
This ignores the scene color managment view settings for solid mode and
lookdev when not using scene lights and world. The scene settings are
intended for tweaking renders and should not affect studio lighting and
matcaps.
There may be cases where a simple sRGB transform is better than Filmic
and we could add configuration for this. Not sure if it really matters
and it may be better if we just assume matcaps and studiolights are all
created for one view transform.

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.
There was a Full Shading bool that was shared across the WP, VP and TP
modes. This commit makes some changes:
- Replace the bool with a factor. This gives the user more control on
the visibility.
- Also draw it on top of the Material and Rendered mode so the user can
control what he needs. In certain cases you don't want to see the final
rendered material, but the actual texture.
- Removed the skipping of objects when in paint modes. As now the paint
modes are blended.
Note: Metaballs only support the first material slot. Splicing it per
material would create empty Batches. In order to overcome this we set
the batch for other materials to NULL. We added extra checks in EEVEE
and Workbench to not draw when the geom is NULL.
