This fixes the issue where sun shadowmaps needs a very big bias value to
make any difference.
The bias is now in world space and not dependant on shadow bounds.
Unfortunatelly this breaks compatibility with previous version and old
scene are likely to need user intervention to fix.
Also fixes the property range.
Fix T71661 EEVEE shadow from sun on incorrect face
This patch will allow the user to select the EEVEE renderpass to be
shown in the viewport by default the combined pass will be shown.
Limitations:
* Viewport rendering stores the result in a `RenderResult`. RenderResult
is not aware of the type of data it holds. In many places where RenderResult
is used it is assumed that it stores a combined pass and the display+view
transform are applied.
I will propose to fix this in a future patch. But that is still being
designed and discussed.

Most of the renderpasses in EEVEE used post-processing on the CPU. For
final image rendering this is sufficient, but when we want to display
the data to the user we don't want to transfer to the CPU to do post
processing to then upload it back to the GPU to display the result.
This patch moves the renderpass postprocessing to a GLSL shader.
This is the first step to do, before we will enable the renderpasses in the viewport.

When rendering the Subsurface scattering lighting render layer with high
sample count render artifacts can appear. This patch will remove these
render artifacts by using a more precise texture format when samples
will be larger than 128. As with the new eevee-shadows it is more common
to use higher number of samples.
The reason why it was visible in the subsurface scattering is that every
sample could change the color. Adding different values will reduce
precision over the number of samples.
The subsurface color render layer also has this issue, but it is not noticeable as
the colors tend to be close to each other so the colors would
most of the time just shift the precision and hold up better.

Add option to change the Intensity of the HDRI in the 3d viewport. This works for both EEVEE and Cycles

This change implements the basics as described in {T68312} for the
shading modes.
* LookDev shading mode is renamed to Material Preview. It always uses Eevee as renderer, and is intended to provide a fast material preview suitable for texture painting, and texture and material setup.
* Rendered shading gains "Use Scene Lights" and "Use Scene World" options similar to current Material Preview. These will be enabled by default. When Use Scene World is turned off, HDRIs will be used for lighting instead. These options are available for EEVEE and Cycles.
* Renderers will be able to customize the shading settings panel and add additional settings.

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.
Related to T65761 Eevee render inconsistency between 3D View, Viewport render, and F12 Render
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`.

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.
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.
When using LookDev in Quad view the cache was only updated for the first
Q-view. The evaluation data of the last cache was not stored with the
lightprobe textures. As the evaluation data was reused between the
Q-views only the lightprobe textures of the first view was updated.
With this patch the evaluated data is stored amongside the actual
lightprobe textures.

This fix saves the camera matrices in order to not call
BKE_animsys_evaluate_animdata during each draw loop. This function tags
the view as dirty even if the camera does not move.
This effectivly, avoids the constant reset of TAA.
This was due to environement not being rendered with alpha blending. So
color was still written and contributed to the final render color. Now
we multiply by background alpha so that it removes any background pixels
intensity.
For this reason this made the (incorrect) final premult unecessary.
* 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.
