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.

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.

In the Python API, helper function `gpu_extras.presets.draw_texture_2d`
still used batch type `TRI_FAN`, which is deprecated since Blender 3.2.
In this patch the batch type is changed to `TRIS`.

When landing #134860 we didn't yet have documentation for the Path
Templates feature. Now that we do, we can refer users to it.
This PR adds a reference to the docs in the type info of properties that
are marked as supporting Path Templates.

Rework internals of how VSE caching is done. Primarily to make all the
caching logic more understandable from development point of view, but
also has several user visible implications (more details in the PR):
- Simpler and fewer caching UI options,
- Disk cache is gone (primary reason: proxies are kinda the same thing),
- VSE cache size set in preferences is actual size used for VSE caches
now (previously caching stopped as soon as whole Blender used that
much memory, even if some memory usage was not about VSE at all),
- Certain scenarios of cache invalidation are faster now.

This adds basic templating support to render output paths. By putting
"{variable_name}" in the path string, it will be replaced by the named
variable's value when generating the actual output path. This is similar
to how "//" is already substituted with the path to the blend file's
current directory.
This templating system is implemented for both the primary render output
path as well as the File Output node in the compositing nodes. Support
for using templates in other places can be implemented in future PRs.
In addition to the "{variable_name}" syntax, some additional syntax is
also supported:
- Since "{" and "}" now have special meaning, "{{" and "}}" are now
escape sequences for literal "{" and "}".
- "{variable_name:format_specifier}", where "format_specifier" is a
special syntax using "#", which allows the user to specify how numeric
variables should be formatted:
- "{variable_name:###}" will format the number as an integer with at
least 3 characters (padding with zeros as needed).
- "{variable_name:.##}" will format the number as a float with
precisely 2 fractional digits.
- "{variable_name:###.##}" will format the number as a float with at
least 3 characters for the integer part and precisely 2 for the
fractional part.
For the primary render output path: if there is a template syntax error,
a variable doesn't exist, or a format specifier isn't valid (e.g. trying
to format a string with "##"), the render that needs to write to the
output path fails with a descriptive error message.
For both the primary and File Output node paths: if there are template
syntax errors the field is highlighted in red in the UI, and a tooltip
describes the offending syntax errors. Note that these do *not* yet
reflect errors due to missing variables. That will be for a follow-up
PR.
In addition to the general system, this PR also implements a limited set
of variables for use in templates, but more can be implemented in future
PRs. The variables added in this PR are:
- `blend_name`: the name of the current blend file without the file
extension.
- `fps`: the frames per second of the current scene.
- `resolution_x` and `resolution_y`: the render output resolution.

Exposes bézier handle data through a new `GreasePencilStrokePointHandle`
class on each point, which provides `position`, `type`, and `select` for both
`point.handle_left` and `point.handle_right`.
Also removes the old separate point attributes:
* `handle_left_type`, `handle_right_type`
* `select_handle_left`, `select_handle_right`

This adds two new python properties to `GreasePencilStrokePoint`
* `select_handle_left`: The selection of the left handle of this point
* `select_handle_right`: The selection of the right handle of this point
These could already be written to using `drawing.attributes[".selection_handle_left"]`
and `drawing.attributes[".selection_handle_right"]`, but this makes it
easier to work on individual points from the higher-level
python API.

Remove long-deprecated constraints that will likely never be
implemented in this form.
- Rigid Body Joint Constraint was removed in 2.80, but some references
remained in the code. Versioning code was written that tried to
remove them on load, but since constraint initialization code sets
the type to CONSTRAINT_TYPE_NULL before versioning gets a chance,
the versioning code ended up never running. This has all been
removed.
- Python/Script Constraint never worked since 2.50 and showed an error
message in the UI panel.
These constraints now load as 'null' constraint, as seems to be
(looking at the code) the way that Blender currently deals with
removed constraint types. These still show up in the outliner and
python API, but have no UI panel. Removing such constraints completely
will be left for another time, as it is beyond the scope of removing
these two specific constraint types.

Some paths in Blender support the `//` prefix for blend-file relative
paths however this is not communicated anywhere.
Support declaring this with a new flag which can be applied to filepath
& dirpath typed properties.
This is used to:
- Show red-alert when "//" are used in paths which don't support a relative prefix.
- Show a warning in the tooltip that the relative suffix is used when unsupported.
- Python warns if this prefix is ever used in an assignment or
function argument.
Resolves#133456.

Make the 'Available' keying set look at the F-Curves for the assigned
slot, instead of the backward-compatible API (which only sees the F-Curves
for the first slot).
Pull Request: https://projects.blender.org/blender/blender/pulls/137131
Previously when an action was baked, the slot name was not retained.
This causes problems when switching between actions because the slot
will not automatically be assigned.
This is now fixed by ensuring that the name of the last assigned slot
is used to create the new slot.

In Geometry Nodes a geometry is represented by a `GeometrySet`. This is a
container that can contain one geometry of each of the supported types (mesh,
curves, volume, grease pencil, pointcloud, instances). It's possible for a
`GeometrySet` to contain e.g. a mesh and a point cloud.
This patch creates a Python wrapper for the built-in `GeometrySet`. For now,
it's main purpose is to consume the complete evaluated geometry of an object
without having to go through complex hoops via `depsgraph.object_instances`. It
also also allows retrieving instances that have been created with legacy
instancing systems such as dupli-verts or particles.
In the future, the `GeometrySet` API could also be used for more kinds of
geometry processing from Python, similar to how we use `GeometrySet` internally
as generic geometry storage.
Since we can't really have constness guarantees in Python currently, it's
enforced that the `GeometrySet` wrapper always has its own copy of each geometry
type (so e.g. it does not share a `Mesh` data-block pointer with any other place
in Blender). Without the copy, changes to the mesh in the geometry set would
also affect the evaluated geometry that Blender sees. The copy has a small cost,
but typically the overhead should be low, because attributes and other run-time
data can still be shared. This should be entirely thread-safe, assuming that no
code modifies implicitly shared data, which is forbidden. For historic reasons
there are still cases like #132423 where this assumption does not hold in all
cases. Those cases should be fixed. To my knowledge, this patch does not
introduce any new such issues or makes existing issues worse.
