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.

This patch implements the Vector Blur node for the Realtime Compositor.
The implementation is a direct and mostly identical port of the EEVEE
motion blur implementation with the necessary adjustments to make it
work with the compositor.
The exposed parameters in the node does not match those exposed in
EEVEE, so only the parameters shared between both are currently
implemented. In the future, we should make a decision to either unify
both, or just consider them independent implementations, with the
possibility of sharing the full or part of the code.
Further, it would also make sense to port the implementation to the CPU
compositor, since the new implementation is higher in quality while also
being faster.
The default value of the node shutter setting was changed to 0.25 to
approximately match the default settings of EEVEE and Cycles, since in
their default settings, they evaluate the previous and next frames at
plus and minus 0.25.

There was one functional issue with the previous API which was its
use in `VolumeGrid<T>::grid_for_write(tree_token)`. The issue was
that the tree token had to be received before the grid is accessed.
However, this `grid_for_write` method might create a copy of the
`VolumeGridData` internally and if it does, the passed in `tree_token`
corresponds to the wrong tree.
The solution is to output the token as part of the method. This has two
additional benefits:
* The API is more safe, because one can't pass an r-value into the methods
anymore. This generally shouldn't be done, because the token should
live at least as long as the OpenVDB tree is used and shouldn't be freed
immediatly.
* The API is a bit simpler, because it's not necessary to call the
`VolumeGrid.tree_access_token()` method anymore.
This simplifies the code that creates the zone socket mappings at the cost of
slightly more memory per zone, which is not significant.
Previously, `IndexRange` was used where it now uses `Vector<int>`.

Even if related, they don't have the same performance
impact.
To avoid any performance hit, we replace the Diffuse
by a Subsurface Closure for legacy EEVEE and
use the subsurface closure only where needed for
EEVEE-Next leveraging the random sampling.
This increases the compatibility with cycles that
doesn't modulate the radius of the subsurface anymore.
This change is only present in EEVEE-Next.
This commit changes the principled BSDF code so that
it is easier to follow the flow of data.
For legacy EEVEE, the SSS switch is moved to a
`radius == -1` check.
`set_default_remaining_node_outputs` didn't work because the mapping
between the original node group sockets and the lazy function outputs
wasn't set up during the construction of the node type, as done by the
bake node and others.
The GPU Directional Blur node does not match CPU. This is because GPU
accumulates the scale, while the CPU increments it. This patch
incremenets the scale for the GPU to make them match.
This commit adds a new helper to define expected properties when a
target needs to use the unity build feature.
That new helper does what was already done for existing cases, and in
addition add the target to the Ninja 'heavy' pooljobs if relevant.

Texture filtering does not work in the GPU compositor. That's because
filtering is set after textures are bound. It works in the viewport
compositor because the textures come pre filtered from the DRW texture
pool.
Along with the 4.1 libraries upgrade, we are bumping the clang-format
version from 8-12 to 17. This affects quite a few files.
If not already the case, you may consider pointing your IDE to the
clang-format binary bundled with the Blender precompiled libraries.
Some common headers were including this. Separating the includes
will ideally lead to better conceptual separation between CustomData
and the attribute API too. Mostly the change is adding the file to
places where it was included indirectly before. But some code is
shuffled around to hopefully better places as well.
This patch implements the defocus node for the Realtime Compositor. The
implementation does not match the CPU compositor implementation, but
uses a new formulation that is more physically accurate and consistent
with Blender's render engines.
The existing CPU implementation is questionable starting from its circle
of confusion calculation, to the morphological operations applied on the
CoC radius, to ignoring the maximum CoC radius in the search kernel, and
ending with the threshold parameter used to reduce artifacts. Therefore,
it should be reimplemented along with this same implementation using a
more consistent methodology.
EEVEE and Workbench already have a GPU defocus method, which can be
ported to the compositor and used as the preview defocus algorithm.
While this implementation will be updated to be a more accurate method
that produces the same structure as the ported EEVEE implementation.
The new formulation ignores the threshold parameter for now, as well as
the preview parameter.

Add a new normal mode called "Custom" which directly interpolates
a "custom_normal" attribute to the evaluated points for the final
normal. Extend the "Set Curve Normal" node with this mode and
give it the ability to set the custom normal value.
This is intentionally a very basic implementation of custom normals.
In particular, the storage is not rotation invariant. So the normals
are expected to be set procedurally at the end of the modifier stack.
On the other hand, it is very easy to understand and explain.

Except for vertex groups and a few older color types, these
are generally replaced by newer generic attribute types.
Also remove some includes of DNA_mesh_types.h, since it's
included indirectly by BKE_mesh.hh currently.
This is the initial implementation for the volume grid sockets that has been
discussed during the November 2023 geometry nodes workshop.
It adds initial support for passing volume grids around in sockets. Furthermore,
it adds two new nodes. Both are initially hidden under the "New Volume Nodes"
experimental option until we have a few mode nodes.
* **Get Named Grid**: Gets or extracts a volume grid from a volume geometry
based on the grid's name.
* **Store Named Grid**: Puts a volume grid back into a volume with a name.
`SocketValueVariant` is extended to support grids besides single values and fields.
Next steps:
* Implement grid socket shape and inferencing (currently, they just look like
single values).
* Add implicit conversions between grid types.
* Implement nodes that operate on the grids (#116021).
* Improved spreadsheet and viewer support.

Remove most includes of this header inside other headers, to remove unnecessary
indirect includes which can have a impact on compile times. In the future we may
want more dedicated "_fwd.hh" headers, but until then, this sticks with the
solution in existing code.
Unfortunately it isn't yet possible to remove the include from `BKE_geometry_set.hh`.
Each value is now out of the global namespace, so they can be shorter
and easier to read. Most of this commit just adds the necessary casting
and namespace specification. `enum class` can be forward declared since
it has a specified size. We will make use of that in the next commit.
This refactors how volume grids are stored with the following new goals in mind:
* Get a **stand-alone volume grid** data structure that can be used by geometry nodes.
Previously, the `VolumeGrid` data structure was tightly coupled with the `Volume` data block.
* Support **implicit sharing of grids and trees**. Previously, it was possible to share data
when multiple `Volume` data blocks loaded grids from the same `.vdb` files but this was
not flexible enough.
* Get a safe API for **lazy-loading and unloading** of grids without requiring explicit calls
to some "load" function all the time.
* Get a safe API for **caching grids from files** that is not coupled to the `Volume` data block.
* Get a **tiered API** for different levels of `openvdb` involvement:
* No `OpenVDB`: Since `WITH_OPENVDB` is optional, it's helpful to have parts of the API that
still work in this case. This makes it possible to write high level code for volumes that does
not require `#ifdef WITH_OPENVDB` checks everywhere. This is in `BKE_volume_grid_fwd.hh`.
* Shallow `OpenVDB`: Code using this API requires `WITH_OPENVDB` checks. However, care
is taken to not include the expensive parts of `OpenVDB` and to use forward declarations as
much as possible. This is in `BKE_volume_grid.hh` and uses `openvdb_fwd.hh`.
* "Full" `OpenVDB`: This API requires more heavy `OpenVDB` includes. Fortunately, it turned
out to be not necessary for the common API. So this is only used for task specific APIs.
At the core of the new API is the `VolumeGridData` type. It's a wrapper around an
`openvdb::Grid` and adds some features on top like implicit sharing, lazy-loading and unloading.
Then there are `GVolumeGrid` and `VolumeGrid` which are containers for a volume grid.
Semantically, each `VolumeGrid` has its own independent grid, but this is cheap due to implicit
sharing. At highest level we currently have the `Volume` data-block which contains a list of
`VolumeGrid`.
```mermaid

Volume --> VolumeGrid --> VolumeGridData --> openvdb::Grid
```
The loading of `.vdb` files is abstracted away behind the volume file cache API. This API makes
it easy to load and reuse entire files and individual grids from disk. It also supports caching
simplify levels for grids on disk.
An important new concept are the "tree access tokens". Whenever some code wants to work
with an openvdb tree, it has to retrieve an access token from the corresponding `VolumeGridData`.
This access token has to be kept alive for as long as the code works with the grid data. The same
token is valid for read and write access. The purpose of these access tokens is to make it possible
to detect when some code is currently working with the openvdb tree. This allows freeing it if it's
possible to reload it later on (e.g. from disk). It's possible to free a tree that is referenced by
multiple owners, but only no one is actively working with. In some sense, this is similar to the
existing `ImageUser` concept.
The most important new files to read are `BKE_volume_grid.hh` and `BKE_volume_grid_file_cache.hh`.
Most other changes are updates to existing code to use the new API.

Use the standard "elements_num" naming, and use the "corner" name rather
than the old "loop" name: `verts_num`, `edges_num`, and `corners_num`.
This matches the existing `faces_num` field which was already renamed.

Extract:
- Compositor error messages.
- `bUnitDef`s were broken after cleanup commit 2b77cd726d. Since each
unit's "display name" is now preceded by a consistent "name_display"
comment, the regex which extracts the unit is greatly simplified.
It now relies on the presence of the comment instead of the struct
order.
- "Preset" menu and "Apply Preset" button from the curveprofile
template.
- Operator labels from the catalog context menu.
Disambiguate:
- "Bake Data": can mean "Which data to bake" (verb), or "The data that
were baked" (noun).
- "Cache" in the Simulation Nodes panel is a verb, not a noun.
- "Mix" in the snapping menu is a noun, not a verb.
- "Top" and "Bottom" can mean the upper part of an object or the
highest point or element of something like a menu or list.

A similar issue was fixed in the commit below for inserting implicit
conversions for links, but it wasn't corrected for conversions in
muted nodes.

Make the naming consistent with the recent change from "loop" to
"corner". Avoid the need for a special type for these triangles by
conveying the semantics in the naming instead.
- `looptris` -> `corner_tris`
- `lt` -> `tri` (or `corner_tri` when there is less context)
- `looptri_index` -> `tri_index` (or `corner_tri_index`)
- `lt->tri[0]` -> `tri[0]`
- `Span<MLoopTri>` -> `Span<int3>`
- `looptri_faces` -> `tri_faces` (or `corner_tri_faces`)
If we followed the naming pattern of "corner_verts" and "edge_verts"
exactly, we'd probably use "tri_corners" instead. But that sounds much
worse and less intuitive to me.
I've found that by using standard vector types for this sort of data,
the commonalities with other areas become much clearer, and code ends
up being naturally more data oriented. Besides that, the consistency
is nice, and we get to mostly remove use of `DNA_meshdata_types.h`.
