HDR video files are properly read into Blender, and can be rendered out
of Blender.
HDR video reading / decoding:
- Two flavors of HDR are recognized, based on color related video
metadata: "PQ" (Rec.2100 Perceptual Quantizer, aka SMPTE 2084) and
"HLG" (Rec.2100 Hybrid-Log-Gamma, aka ARIB STD B67). Both are read
effectively into floating point images, and their color space
transformations are done through OpenColorIO.
- The OCIO config shipped in Blender has been extended to contain
Rec.2100-PQ and Rec.2100-HLG color spaces.
- Note that if you already had a HDR video in sequencer or movie clip,
it would have looked "incorrect" previously, and it will continue to
look incorrect, since it already has "wrong" color space assigned to
it. Either re-add it (which should assign the correct color space),
or manually change the color space to PQ or HLG one as needed.
HDR video writing / encoding"
- For H.265 and AV1 the video encoding options now display the HDR mode.
Similar to reading, there are PQ and HLG HDR mode options.
- Reference white is assumed to be 100 nits.
- YUV uses "full" ("PC/jpeg") color range.
- No mastering display metadata is written into the video file, since
generally that information is not known inside Blender.

The grid layout type for UI list is planned for removal in 5.0, see
blender/blender#110461.
In previous UI meetings, we talked about deprecating the Grid mode of
the UI list, which is not actually accessible in UI and was never used.
Nowadays, there is a new grid view that can be exposed in the API in
the future.
Initially, I wanted to remove references to layout_type in UI templates
in the text editor, because a lot of add-on developers on the
extensions platform base their lists on that code, and a lot of them
are therefore including soon to be deprecated code in their add-ons,
which I want to avoid in the future. But I thought we might as well
remove it from our python scripts as well, since it's just basically
redundant code that doesn't do anything. And also because many add-on
developers use bundled python scripts for references as well.

This changes the engine identifier back to `BLENDER_EEVEE`.
We keep the `BLENDER_EEVEE_NEXT` identifier around for
versioning reasons (have to detect when it is the active
engine of a older file).
This also rename a bunch of pannels that were using `next`
in their name.
This is a breaking change for Addons compatibility.

ProRes is a common intra-frame codec in post-production work, supported
by a wide range of post-production software.
This PR adds support for direct output from Blender using the ProRes
codec from FFmpeg. Alpha is supported, along with 8 and 10-bit channel
images.

Add a "Pixel Density" sub-panel to render output settings which
can be used to set the density (as pixels per inch for example).
This is then written to images that support pixel density.
Details:
- The scene has two values a PPM factor and a and base unit.
- The base unit defaults to pixels per inch as this is the most
common unit used.
- Unit presets for pixels per inch/centimeter/meter are included.
- The pixel density is stored in the render result & EXR cache.
- For non 1:1 aspect renders, the density increases on the axis
which looks "stretched", so the PPM will print the correct
aspect with non-square pixels.

Before this patch, Video Output using FFmpeg video
display lot of parameters.
But some of theses have a meaning only for some codec
(mainly lossy gop codecs : H264, H265, AV1...)
Hide not useful parameters for codec :
'DNXHD', 'FFV1', 'HUFFYUV', 'PNG', 'QTRLE'
- DNXHD : intra frame codec, encoding setting depends of a profile
- FFV1/QTRLE : Intra or P frames only. Lossless codec
- HUFFYUV/PNG : Intra lossless codec

Previously, code related to reading/writing movie files via ffmpeg was
scattered around: some under blenkernel, some directly in generic
imbuf headers, some under intern/ffmpeg. Some of the files were named
with not exactly clear names. Some parts not directly related to movies
were including ffmpeg headers directly (rna_scene.cc).
What is in this PR:
Movie and ffmpeg related code is now under imbuf/movie:
- IMB_anim.hh: movie reading, proxy querying, various utility functions.
- IMB_movie_enums.hh: simple enum definitions,
- IMB_movie_write.hh: movie writing functions.
- intern: actual implementation and private headers.
- ffmpeg_compat.h: various ffmpeg version difference handling
utilities,
- ffmpeg_swscale.hh/cc: scaling and format conversion utilities
for ffmpeg libswscale,
- ffmpeg_util.hh/cc: misc utilities related to ffmpeg,
- movie_proxy_indexer.hh/cc: proxies and timecode indexing for movies,
- movie_read.hh/cc: decoding of movies into images,
- movie_write.cc: encoding of images into movies.
- tests: basic ffmpeg library unit tests that previously
lived under intern/ffmpeg.
Interface changes (at C++ level, no Python API changes):
- Mostly just movie related functions that were BKE_ previously, are now IMB_.
- I did one large-ish change though, and that is to remove bMovieHandle
struct that had pointers to several functions. Now that is
IMB_movie_write_begin, IMB_movie_write_append, IMB_movie_write_end
functions using a single opaque struct handle. As a result, usages
of that in pipeline.cc and render_opengl.cc have changed.

Part of overall #118493 task: video input/output support at 10 and 12
bit/component formats. (note: this is still LDR videos just at higher
precision; there's no HDR handling (yet)).
Movie reading/playback: when movie file pixel format has >8 bit
components, decode those into a floating point ImBuf result. Previously
all movies were decoded into 8 bit/channel ImBufs, so 10- and 12-bit
movie pixel colors were getting quantized.
Movie output: when ffmpeg video with suitable codec is selected,
there's a color depth setting under Encoding block. Currently that is:
- 10 bit option for H.264, H.265, AV1 (VP9 could do 10 bit in theory too,
but ffmpeg that is built in Blender does not have that compiled in)
- 12 bit option for H.265, AV1
When "lossless" is picked, then similar to how for regular 8-bit video
it switches from YUV 4:2:0 to 4:4:4, this also switches to 4:4:4
10- or 12-bit variant.
Pull Request: https://projects.blender.org/blender/blender/pulls/129298
Now can pick "H.265 / HEVC" in the video codec dropdown.
Implementation notes:
- Remap CRF value (which is for H.264) slightly to better match H.265
CRF range (e.g. default Medium 23 -> 28).
- Set lossless mode via appropriate private param, and use 4:4:4 YUV
format just like for some other video codecs when in lossless.
- Currently there are no built-in presets for H.265. Maybe later, especially
if/when we'll add 10 bit or HDR videos.

Part of modernizing scripts in Blender, where the previous convention
was to use percentage formatting which has become the "old" way to
format strings in Python.
See proposal for details #120453.
Ref !120552
The previous commit introduced a new `RPT_()` macro to translate
strings which are not tooltips or regular interface elements, but
longer reports or statuses.
This commit uses the new macro to translate many strings all over the
UI.
Most of it is a simple replace from `TIP_()` or `IFACE_()` to
`RPT_()`, but there are some additional changes:
- A few translations inside `BKE_report()` are removed altogether
because they are already handled by the translation system.
- Messages inside `UI_but_disable()` are no longer translated
manually, but they are handled by a new regex in the translation
system.

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.

- The official spelling of FFMPEG is FFmpeg (upper, then lower case).
- The normal vector copy and paste operators shoud be singular because
they can only be used on a single element.
- The "Parent File" file browser operator goes up one level in the
file hierarchy. It should be called "Parent Directory", like the
current description "Go to the parent directory".
- "Mass Vertex Group" used to define the mass, but was reused at some
point and now actually defines cloth pinning so it should be called
"Pin Vertex Group", as in the UI.
- The Transformation constraint's Map To Type suffered from a
typo (probably of -> on).
- "Fall-off" is more commonly spelled "Falloff".
- "Effected" should really be "Affected" in this case.
- Rephrase the descriptions for the curve painting tools drawing
plane, which did not seem to match what the settings do. Namely,
they allow selecting in which plane to draw curves using the Curve
Draw tool.

- "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.

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).
