Introduced in 4434a30d40
The above commit changed many of the `wm.radial_control` default
keybinds used in various paint modes to support accessing the "unified"
properties on a per-mode basis. While the base Blender keymap and the
industry compatible keymap were updated, this change was not applied
to custom keymaps, leading to confusing behavior for the users.

Ensure that `__main__.__file__` is not set to "<blender string>" when
spawning the subprocess for the background downloader. Blender sets this
value when executing a Python string from C++ code. However, this value
causes issues with Python's `multiprocessing` module, as it expects that
IF the attribute is set, it contains the actual file of the actual main
module. Clearing it works fine, as `__file__` is optional anyway.

Add a [Python code generator][1] that takes an OpenAPI definition and
outputs the corresponding data model as [dataclasses][2]
This is intended to be used in the Remote Asset Library project, to
create, download, parse, and validate information of a remote asset
library.
[1]: https://koxudaxi.github.io/datamodel-code-generator/
[2]: https://docs.python.org/3/library/dataclasses.html
## Running the Generator
The generator is a Python script, which creates its own Python
virtualenv, installs the dependencies it needs, and then runs the
generator within that virtualenv.
The script is intended to run via the `generate_datamodels` CMake
target. For example, `ninja generate_datamodels` in the build
directory.
## Details
The virtualenv is created in Blender's build directory, and is not
cleaned up after running. This means that subsequent runs will just
use it directly, instead of reinstalling dependencies on every run.
## Generated Code & Interaction with Build System
It is my intention that the code generation _only_ happens when the
OpenAPI specification changes. This means that the generated code will
be committed to Git like any hand-written code. Building Blender will
therefore _not_ require the code generator to run. Only people working
on the area that uses the generated code will have to deal with this.

Add a new package `scripts/modules/_bpy_internal/http`, containing
classes to download files via HTTP.
The code is intentionally put into the `_bpy_internal` package, as I
don't intend it to be the end-all-be-all of downloaders for general
use in add-ons. It's been written to support the Remote Asset Library
project (#134495), where it will be used to download JSON files (to
get the list of assets on the server) as well as the asset files
themselves.
The module consists of several parts. The main ones are:
`class ConditionalDownloader`
: File downloader, which downloads a URL to a file on disk.
It supports conditional requests via `ETag`/`If-None-Match` and
`Last-Modified`/`If-Modified-Since` HTTP headers (RFC 7273, section 3.
Precondition Header Fields). A `304 Not Modified` response is
treated as a succesful download.
Metadata of the request (the response length in bytes, and the above
headers) are stored on disk, in a location that is determined by the
user of the class. Probably in the future it would be nice to have a
single sqlite database for this (there's a TODO in the code about
this).
The downloader uses the Requests library, and manages its own HTTP
session object. This way it can handle TCP/IP connection reuse,
automatically retry failing connections, and in the future
HTTP-level authentication.
`class BackgroundDownloader`
: Wrapper for a `ConditionalDownloader` that manages a background
process for the actual downloading.
It runs the downloader in a background process, while ensuring that
its reporters (see below) get called on the main process. This way
it's possible to do background downloading, while still receiving
progress reports in a modal operator, which in turn can directly
call Blender's Python API. Care was taken to [not use Python
threads][1]
`class DownloadReporter`
: Protocol class. Objects adhering to the protocol can be given to a
`ConditionalDownloader` or `BackgroundDownloader`. The protocol has
functions like `download_starts(…)`, `download_progress(…)`,
`download_error(…)`, which will be called by the downloader to
report on what it's doing.
I chose to make this a protocol, rather than an abstract superclass,
because then it's possible to make an Operator a DownloadReporter
without requiring multi-classing.

Deprecation meta-data support for RNA properties.
- Properties may have a deprecated note and version.
- Warnings shown when these are accessed from Python.
- A note is included in the generated documentation.
Support for marking functions as deprecated can be added in the future.
Ref !139487
"Strip" generally is a sequencer or animation strip, but in this
context it is a string manipulation action for file names. It is
defined as part of the Path Mode defined in the FBX and OBJ exporters.
Those exporters are defined in Python and C++, respectively. This
commit changes both exporters to use the "File browser" translation
context.
In addition, the tooltip for "Relative" from the FBX exporter was
changed to match its OBJ counterpart, and the "Strip Path" mode was
also matched to the other version which reads better as an enum item.
Reported by Ye Gui in #43295.
Commit 9ce0a2d1d5 added the ability to specify translation contexts to
node UI panels, but it failed to update the regex that extracts them.
This commit solves that by adding the proper `add_panel` function to
the extraction regex.
Reported by Satoshi Yamasaki in #43295.
Job names displayed in the status bar were not extracted or
translated. This commit adds a regex to the bl_i18n_utils settings to
detect `WM_jobs_get()`, and the `RPT_` translation macro to translate
the message in the UI.
About 30 new messages are translated.
Reported by Ye Gui in #43295.
Geometry Nodes' Add > Input > Import menu includes file format items
such as "Standford PLY (.ply)", "STL (.stl)", "Text (.txt)". The
latter needs to be translated because "Text" is a generic format.
These items are declared using a custom function
`node_add_menu.add_node_type`, with a `label` argument. This commit
adds the `label` argument to the function arguments that can be
extracted from specific node declaration functions, and specifies the
argument position for each:
"add_node_type", "add_node_type_with_outputs", "add_simulation_zone",
"add_repeat_zone", "add_foreach_geometry_element_zone",
"add_closure_zone".
There is currently no facility to specify a translation context but it
could be easily added if the need arises.
Most of these functions do not actually declare new, unique messages,
but it could happen in the future. In addition, two messages were
extracted using manual `iface_()` calls, which are no longer needed
after this change.
Reported by Ye Gui in #43295.
This PR makes it easier to add keyframes for strips in preview.
This works same way as in 3D viewport, using keying sets. Pressing I
key adds keyframe to default keying set, pressing K dhows menu with
available keying sets. For VSE, location, rotation and scale properties
are available for now. Other existing keying sets are not valid for
VSE.
Deleting keyframes and potentially adding more keying sets will be
handled in separate PR.

This new file can parse the file header (first few bytes) as well as the block
headers.
Right now, this is used by two places:
* `blendfile.py` which is used by `blend2json.py`
* `blend_render_info.py`
This new module is shipped with Blender because it's needed for
`blend_render_info.py` which is shipped with Blender too. This makes using it in
`blendfile.py` (which is not shipped with Blender) a bit more annoying. However,
this is already not ideal, because e.g. `blend2json` also has to add to
`sys.path` already to be able to import `blendfile.py`.
This new file could also be used by blender-asset-tracer (BAT).
The new `BlendFileHeader` and `BlockHeader` types may be subclassed by code
using it, because it wants to store additional derived data (`blendfile.py` and
BAT need this).
New tests have been added that check that the file and block header is parsed
correctly for different kinds of .blend files.

Change the maximum data-block name from 64 to 256 bytes by increasing MAX_ID_NAME value.
Also increase a few related non-ID data name max size, essentially the action slots identifiers, as these are the primary key used to match an Action's slot to an ID by name.
Other sub-data (bones, modifiers, etc.) lengths are not modified here, as these can be made actual dynamic strings in the future, while keeping (a reasonable level of) forward compatibility, during the course of Blender 5 release cycles.
Implements #137608.

This is replaced by geometry nodes, where volumes can now be generated from
point clouds and meshes with more control, and more efficient rendering as a
sparse volume.
No backwareds compatibility is provided, as this would be complicated, and
probably this feature was not used much in the past few years.
This node was supported in Cycles only, not by EEVEE.

Edit the language list to make it simpler to scan.
- Display languages in a form "Language (Variant)", such as
"English (US)" instead of "American English" and
"Portuguese (Brazil)" instead of "Brazilian Portuguese".
This allows alphabetical sorting by language first.
This does not apply to endonyms (languages in their own language).
- Use a dash instead of parentheses to separate the endonyms.
- Deduplicate languages (Automatic, American English, British
English), which all are in English and don't appear in another
language.
- Remove language categories as headers. They are replaced with
percentages in the language tooltips. The percentages are
generated in utils_languages_menu.py and stored in
locale/languages.

This allows to reduce the waiting time caused by
shader compilation on some GPU-driver combo.
A new settings in the User Preferences make it
possible to override the default amount of worker
threads and optionally use subprocesses.
We still use only one worker thread in cases where
there is no benefit with adding more workers
(like AMD pro driver and Intel windows).
It doesn't scale as much as subprocesses for material
shader compilation but that is for other reasons
explained in #139818.
Add some heuristic to avoid too much memory usage
and / or too many stalls.
Also add some heuristic to the default number of subprocess for
the platform that shows scalling.
Historically, multithreaded compilation was prevented by the
need of context per thread inside `DRWShader` module.
Also there was no good scaling at that time. But
nowadays numbers shows different results with
good scaling with reasonable amount of threads on many
platforms.
Even if we are going for vulkan in the next release
most of the legacy hardware will still use OpenGL for
a few other releases. So it is relevant to make this
easy improvement.
See pull request for measurements.

Removes various image filtering/mipmapping leftovers from
pre-2.80 days.
Code: removes all mipmap handling from ImBuf (which is about half of
ImBuf struct size), removes now unused "sample procedural texture
with mipmaps" code, now-unused FELINE filter, etc. The osatex
parameter to various CPU texture sampling functions is never
actually used, which means none of the mipmap code was ever executing.
User visible part: there were settings on the legacy Texture data
block (as used by Brushes etc.), under Sampling section: "MIP Map",
"Gaussian Filter", "Filter Type", "Eccentricity", "Minimum Size" --
they had no effect anywhere, so they are gone, and what remains is
only "Interpolation" and "Size".
RNA / Python API part: removes the ImageTexture RNA properties
corresponding to the above: filter_type, use_mipmap, use_mipmap_gauss,
filter_lightprobes, filter_eccentricity, use_filter_size_min.

e.g. stands for "exempli gratia" in Latin which means "for example".
The best way to make sure it makes sense when writing is to just expand
it to "for example". In these cases where the text was "for e.g.", that
leaves us with "for for example" which makes no sense. This commit fixes
all 110 cases, mostly just just replacing the words with "for example",
but also restructuring the text a bit more in a few cases, mostly by
moving "e.g." to the beginning of a list in parentheses.
