This will have multiple benefit.
TODO detail benefits (culling, more explicit, handling of clipping planes)
For now the view usage is wrapped to make changes needed more progressive.
There is now a checkbox to enable/disable depth of field per camera. For Eevee
this replace the scene level setting. For Cycles there is now only an F-Stop
value, no longer a Radius.
Existing files are converted based on Cycles or Eevee being set in the scene.

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`.

When using Intel GPU EEVEE did not display anything. This was due to an
internal shader compilation bug inside the intel drivers. We had fixed
this for other vertex shaders. The same change we have to apply to other
vert shaders that want to limit the need of Matrix multiplications.
This is the angular diameter as seen from earth, which is between 0.526° and
0.545° in reality. Sharing the size with other light types did not make much
sense and meant the unit was unclear.

This is a big change that cleanup a lot of confusing code.
- The instancing/batching data buffer distribution in draw_instance_data.c.
- The selection & drawing code in draw_manager_exec.c
- Prety much every non-meshes object drawing (object_mode.c).
Most of the changes are just renaming but there still a chance a typo might
have sneek through.
The Batching/Instancing Shading groups are replace by DRWCallBuffers. This
is cleaner and conceptually more in line with what a DRWShadingGroup should
be.
There is still some little confusion in draw_common.c where some function
takes shgroup as input and some don't.
Cycles lights now use strength and color properties of the light outside
of the shading nodes, just like Eevee. The shading nodes then act as a
multiplier on this, and become optional unless textures, fallof or other
effects are desired.
Backwards compatibility is not exact, as we can't be sure which renderer
the .blend was designed for or even if it was designed for a single one.
If the render engine in the active scene is set to Cycles, lights are
converted to ensure overall light strength remains the same, and removing
unnecessary shader node setups that only included a single emission node.
If the engine is set to Eevee, we increase strength to remove the automatic
100x multiplier that was there to match Cycles.

This change the logic a bit, when 2 bsdfs using SSS are mixed, we use the
one with the biggest radius (on a per pixel basis).
This change from previous behavior which was to select input 1 if radius
was greater than 0.
Note: Some adjustments were made compared to the diff mainly for code
readability and made the default ball size 150px.

Workbench/Eevee now displays multiple multi-materials correctly.
Iterate over pbvh nodes when doing object iteration. This makes the
rendering process more streamlined and allow for using different materials.
This change will make possible to:
- Add culling pass of each pbvh leaf node. (speedup if zoomed on a small
area)
- Reduce number of lead node iteration.
- Reduce code complexity
- 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.
