Relative imports are intentionally avoided in UI code (`scripts/startup/bl_ui`) because it makes it impossible to run individual files in isolation.
Common workflow for making mock-ups and quick UI edits is to load the UI file in Blender's text editor with "Edit Source" operator, make changes, and run the script to see the changes. But in the current version it's impossible because files include relative imports, which don't allow Python to run scripts individually.

Set `use_property_decorate = False` in the Animation panels in the
Properties editor. This has no visual effect right now, but if we ever
decide to add labels to the selectors, this will ensure that the layout
remains correct.
Context: `layout.template_action()` and `layout.template_search()` respond
differently to the default of `use_property_decorate = True`.
Add Action + Action Slot selectors to various Property Editor tabs.
This follows the pattern established in
f917b60036.
Support for `CacheFile` data-blocks is not included here. That needs
some discussion, as currently its interface is part of the Modifier
stack (and thus implemented in C++ and not Python, and using a
different layout).
Since this PR is about adding to the Property Editor, some data-blocks
that have no representation there are thus excluded (like `Mask`).
Even when they could actually use an Action+Slot selector somewhere.

Sun extraction convert part of light comming from the world to a
sun light which increases the quality of the rendering. The goal
of this feature is to workaround the limitation of the storage
techniques used for environment lighting inside EEVEE.
This first implementation works by clamping the world lighting and
summing the excess lighting and (and its incomming directions) to
deduce the sun position.
All the lighting is then transfered into this light power. The sun
angle is computed based on the directionnality of the excess lighting,
the more divergent the excess lighting is, the bigger the angle.
This has a few benefits:
- It's stable and behave well under animation. This is because we
average a lot of data.
- It's fast as it can be done inside the remap shader in one pass.
- It requires only one parameter, the clamp threshold.
However, it has some issue:
- It modifies the lighting as we change the incomming direction for
excess lighting away from the chosen sun direction. This could be fixed
by masking only lighting around the chosen sun direction (requires 2
passes, slower).
- Given that this only average the direction, it behaves poorly if there
two opposite bright light sources (it puts the sun in the middle). This
could be fixed by extracting more suns, but that becomes more complex
and requires even more passes.
- It looks bad if the summed lighting is not supposed to be a perfect
disk in specular reflections or if the sources are too divergent as the
disk is too big and the approximation fails short. This could be
mitigated by adding an upper bound to the sun radius. For now we
workaround this issue by exposing the sun angle parameter in the UI.
A more precise algorithm can be implemented in the future to avoid
having to deal with these limitations. A possibility is to use
importance sampling to randomize sun position. But that would be only
for final render.

EEVEE-Next world volume are infinite like Cycles. EEVEE-Classic world volumes
end at the clip_end of the camera/viewport. This can lead to confusion as
it would render different then expected.
This PR adds an operator to convert a world volume into a mesh volume. The
operator can be found in the shader editor (world mode) and in the properties
panel/World/Volume.
**Why an operator?**
As this alters the content of the scene we want the artist to be in control of
the conversion. Doing it automatic lead to a lot of complexity and cases that
might not be expected by the user.

The Volume input of the world didn't show up inside the property panel.
Reason was that the panel didn't have EEVEE-Next inside its list of compatible
engines.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
All probes (including the world background probe) are stored in a single texture. Each probe
can be of any resolution as long as it is a power of 2 and not larger than 2048. So valid options
are (2048x2048, 1024x1024, 512x512, etc).
Each probe can be stored in their own resolution and can be set by the user.
> NOTE: Eventually we would like to add automatic resolution selection.
The probes are packed in an 2d texture array with the dimension of 2048*2048. The number of
layers depends on the actual needed layers. If more layers are needed the texture will be recreated.
This can happen when a new reflection probe is added, or an existing reflection probe is made visible
to the scene or its resolution is changed.
### Octahedral mapping
Probes are rendered into a cubemap. To reduce memory needs and improve sampling performance the cubemap
is stored in octahedral mapping space. This is done in `eevee_reflection_probe_remap_comp.glsl`.
The regular octahedral mapping has been extended to fix leakages at the edges of the texture
and to be able to be used on an atlas texture and by sampling the texture once.
To reduce sampling cost and improve the quality we add an border around the
octahedral map and extend the octahedral coordinates. This also allows us to
generate lower resolution mipmaps of the atlas texture using 2x2 box filtering
from a higher resolution.
### Subdivisions and areas
Probes data are stored besides the texture. The data is used to find out where the probe is stored
in the texture. It is also used to find free space to store new probes.
This approach ensures that we can be flexible at storing probes with different
resolutions on the same layer. Lets see an example how that works
Code-wise this is implemented by `ProbeLocationFinder`. ProbeLocationFinder can view a texture in a
given subdivision level and mark areas that are covered by probes. When finding a free spot it returns
the first empty area.
**Notes**
* Currently the cubemap is rendered with a fixed resolution and mipmaps are generated in order to
increase the quality of the atlas. Eventually we should use dynamic resolution and no mipmaps.
This will be done as part of the light probe baking change.

- "Lens" can be a transparent object used in cameras, or specifically
its property of focal length
- "Empty" can be an adjective meaning void, or an object type. The
latter is already disambiguated using `ID_ID`
- "New" and "Old" are adjectives that can have agreements in some
languages
- "Modified" is an adjective that can have agreement in some languages
- "Clipping" can be a property of a camera, or a behavior of the
mirror modifier
- "Value" in HSV nodes, see #105113
- "Area" in the Face Area geometry node, can mean a measurement or a
window type
- "New" is an adjective that can have agreement
- "Tab" can be a UI element or a whitespace character
- "Volume" can mean a measurement or an object type. The latter is
already disambiguated using `ID_ID`
These changes introduce the new `BLT_I18NCONTEXT_TIME` translation
context.
They also remove `BLT_I18NCONTEXT_VIRTUAL_REALITY`, which I added at
one point but then couldn't find which messages I wanted to fix with
it.
Ref #43295
Pull Request: #106718
This commit implements described in the #104573.
The goal is to fix the confusion of the submodule hashes change, which are not
ideal for any of the supported git-module configuration (they are either always
visible causing confusion, or silently staged and committed, also causing
confusion).
This commit replaces submodules with a checkout of addons and addons_contrib,
covered by the .gitignore, and locale and developer tools are moved to the
main repository.
This also changes the paths:
- /release/scripts are moved to the /scripts
- /source/tools are moved to the /tools
- /release/datafiles/locale is moved to /locale
This is done to avoid conflicts when using bisect, and also allow buildbot to
automatically "recover" wgen building older or newer branches/patches.
Running `make update` will initialize the local checkout to the changed
repository configuration.
Another aspect of the change is that the make update will support Github style
of remote organization (origin remote pointing to thy fork, upstream remote
pointing to the upstream blender/blender.git).
