820f0c24c4 Mesh: Add versioning to convert old face maps to boolean attributes
See #105317

In 46cf093270, face maps were just converted to an integer
attribute. While the internal data remains the same that way, we lose
the names and some convenient methods of interaction. This commit
additionally converts each face map to a separate boolean attribute
using the old name. This does require that no attributes were using that
name already.

Each boolean attribute can be thought of as a selection, accessible in
geometry nodes and properly interpolated by mesh processing
algorithms. The selections no longer have to be unique, meaning
one face can be part of multiple selections.

9859622a66 BKE_reports: make the API thread-safe.
This commit makes using (most of) `BKE_report` API safe in
multi-threaded situation.

This is achieved by adding a `std::mutex` lock to the `ReportList`
struct (in a slightly convoluted way unfortunately, due to this being a
DNA struct). This lock is then used to make most operations on
`Reportlist` data thread-safe.

Note that while working on this, a few other minor issues aroze in
existing usages of Reportlist by the WM code, mainly the fact that
`wm_init_reports` and `wm_free_reports` were both useless:
  - init was called in a context where there is not yet any WM, so it
    was doing nothing.
  - free was called on a WM that would be later freed (as part of Main
    freeing), which would also call cleanup code for its `reports` data.
Both have been removed.

Further more, `wm_add_default` (which is the only place where a WM ID is
created) did not initialize properly it reports data, this has been
fixed.

This change is related to the wmJob thread-safety tasks and PRs (#112537,
!113548).

2d703e9200 I18n: add label declaration to node sockets so they can be shortened
In !112591, nodes got the ability to group sockets into panels. The
labels for these sockets are automatically shortened if they begin
with the same text as their parent labels. For instance, "Transmission
Weight" will be shortened to just "Weight" because it is under the
"Transmission" panel.

While this is a good heuristic for English, it breaks down in
languages which do not have the same word order.

This commit adds a `.short_label()` callback to socket declarations so
that a shortened label can be explicitly declared.

It also adds two regexps to the translation script so that these new
fields can be extracted to the .po translation files. One extracts the
label with a translation context, the other without. Only the one
without context is currently in use.

The current automatic shortening logic is kept and will be used only
if a shortened label is not manually provided.

Fixes #112970: Node socket labels under panels are not shortened when
translated.

20d8f27ed2 Geometry Nodes: Add default input option for node groups
In order to recreate the behavior of some builtin nodes
which have implicit inputs for ID/Index or positions, provide
a hard-coded list of default/unconnected fields for sockets.

The point is to let assets recreate the behavior of builtin
nodes in a simple way that's easy to change in the future if
this becomes a more generalized feature. A hardcoded list
makes this predictable and simple in the meantime.

When the option is set to something besides "Default Value"
it overrides the "Hide Value" option. Otherwise the default
input would conflict with the visible default value button.

This makes it possible to add #109846 as an asset in the
essentials bundle. The design is meant to be easily
extendable for shader nodes, though that isn't included
in this commit.

f43426f0de GPv3: Rename layer domain to just "Layer"
We had a short discussion on this change. "Grease Pencil Layer" is
just a bit too long, especially in the UI. Even though "Layer" might be
ambiguous, it shouldn't be in the context of geometry nodes. There are
currently no other "Layers" and if there were, using the same domain
name could be fine (just like we reuse the point domain for e.g. vertices
in meshes and control points in curves).

This also renames the internal enum to `ATTR_DOMAIN_LAYER`

25a1cea8e2 EEVEE-Next: Scene Reflection Probe Resolution
This PR reuses the scene specific reflection probe resolution for all
reflection light probes in the scene. The target is to have a automatic
detection for the resolution. But as long as we don't have a mechanism
for detection it is better to not introduce a new UI element that will
be removed within the foreseen future.

This setting is currently used by EEVEE and EEVEE-Next. EEVEE supports
resolutions upto 4096px. This will be clamped to 2048 when using
EEVEE-Next.

The motivation for this is that EEVEE-Next will soon replace
EEVEE and 4096 can then be removed from the choices that the user can
made. Adding as separate option could need synchronization, and that
option would also be temporary as it will be removed by the resolution
detection mechanism.

1ccba4d9fe Nodes: Use index instead of reordering for draw order
Currently nodes are reordered so that the "on top" nodes are last in
the list. Node order changing for simple operations like selection
means we either have to reevaluate the node tree data-block on
selections or accept that the evaluated order can be different from the
original. Currently we do the latter (see d76a0e98ba), but
makes it complex to access nodes by index, and is hard to reason about.

Instead of reordering nodes, store the ui order in the node itself
and sort the nodes before drawing them or doing any processing
that depends on the "depth."

The "selected_nodes" list in the context is no longer ordered by the
recent selection.

61b463d5e4 EEVEE-Next: Planar Probe Pipeline
This PR is contains the initial capture pipeline for planar probes.

It requires work to generate the correct view to capture and to include
the result during ray tracing. These will be developed in a separate PR.

This PR detects if a planar probe is active in the scene. If this is
the case the planar probe pipeline will be activated. During rendering
this is done by querying the depsgraph, during viewport drawing this
is done during sync. If an planar probe is detected and the pipeline
wasn't activated. The pipeline will be activated and the sampling
will be reset to ensure the pipeline is filled with all objects.

Per object the user can set the visibility of the object in planar
reflections.

For a reflection plane the resolution and clipping offset can be set.
EDIT: Resolution option was removed because too complex to
implement with the little time we have at the moment.

7e87435cf4 GPv3: Initial drawing tool
This PR implements an initial drawing tool that can already be used for testing.
While this is not fully feature complete (compared to the current grease pencil draw tool) the following is already implemented:

* Pressure support for radius and opacity.
* Material color and vertex color support.
* New active smoothing algorithm based on curve fitting.
* Simplify algorithm as a post-process step.

Some deliberate limitations include:
* The drawing plane is always the front plane. Drawing on surfaces is also not supported.
*

The current approach has not been optimized for performance yet. The goal was to have a straightforward implementation
first and then focus on performance later.

There are numerous parameters in the code that are hard-coded for now. These should be exposed at some point, potentially as user settings.

b4de568cc4 EEVEE-Next: Tests support
Enable tests for EEVEE Next.

As a workaround for allowing the use of EEVEE Next (still an
experimental feature) with `--factory-startup`, `arg_handle_engine_set`
enables the feature when `-E BLENDER_EEVEE_NEXT` is used.
In addition, EEVEE Next is always registered, so it's available when
calling `WM_init`.
If it's actually disabled, it will be immediately unregistered after that.

Notes:
- `get_gpu_device_type` always fails with error:
  > GPU API is not available in background mode
- Setup and tests are the same as EEVEE. There are many tests that
  only make sense for Cycles, and many EEVEE Next features that are
  not actually tested.

012289b1e7 Geometry Nodes: deduplicate code to deal with dynamic socket amounts
The goal of this refactor is to reduce the amount of boilerplate code that is
necessary to have a dynamic number of sockets on nodes. This is achieved
by making the code more reusable. Currently, only the simulation and repeat
zone nodes make use of this. However, even with just those two, the amount
of code is reduced already. The benefit of this refactor will become even more
significant as more nodes support a dynamic number of sockets. For example,
the bake node and for-each zone will also benefit from this.

We could probably make some of the utility functions non-templates using type
erasure. This could reduce the compilation overhead when the number of nodes
with item arrays increases. The main reason for why everything is templated
now is that it made this refactor easier. Without this patch, all the code was
essentially "manually templated". So the implementations look still similar to
before now, just that concrete types are replaced with template parameters.

No user-visible changes are expected.

75c947a467 Compositor: Use RBF Interpolation in Keying Screen node
This patch changes the interpolation algorithm utilized by the Keying
Screen node to a Gaussian Radial Basis Function Interpolation. This is
proposed because the current Voronoi triangulation based interpolation
has the following properties:

- Not temporally stable since the triangulation can abruptly change as
  tracking markers change position.
- Not smooth in the mathematical sense, which is also readily visible in
  the artists sense.
- Computationally expensive due to the triangulation and naive
  rasterization algorithm.

On the other hand, the RBF interpolation method is temporally stable and
continuous, smooth and infinitely differentiable, and relatively simple
to compute assuming low number of markers, which is typically the case
for keying screen objects.

This breaks backward compatibility, but the keying screen is only used
as a secondary input for keying in typical compositor setups, so one
should expect minimal difference in outputs.

As an alternative to !109746 (where it was made sure all places would
make the right assumption about mat_nr starting at 1), this PR now
changes the mat_nr to be zero-based.

This is more in line with other places handling material indices.

fb556c75df Snap: New icons
For Blender 4.0 we decided to support individual icons for different
snap elements.

This was originally contributed by Erik Abrahamsson as !107054 with
some contributions by myself (Germano).

This set of icons being simple geometric symbols, that should be
familiar to CAD artists.

Note that Face and Volume share the same icon (circle). This is
deliberate since they communicate a similar functionality - are not
aimed at precision snapping the same way the vertex or perpendicular
are.

Also note that later we should also try to change the icons shown in
the snap menu to match the symbols that the artists see in the preview
window.

———

On the decision process:

The version currently in main (and rolled back here) was an initial
attempt of aggregating more information to the icons (e.g., by aligning
the icons to the target edges) while making them more suitable to
Blender. After presenting both options to (parts of the) community,
there was nothing fundamentally broken found with either option, though
options diverged over personal preference.

With that in mind, in the latest UI module meeting it was agreed to use
the original proposal then.

This final call was proposed by Dalai Felinto on his role of
commissioner (stakeholder) for the snap polishing tasks (#73993) and
designer for the related Snap Base design #66484.

———

This commit reverts commit 9c2e768f5b.

The reverted icons (referred originally as minimalistic icons) may be
proposed later as a separate theme option.

bc7034d9fd CurvesGeometry: Add initial vertex group support
This PR adds vertex groups to `CurvesGeometry` as well as an attribute read/write accessor.

This is also in preparation for GPv3. Since the goal is to have full compatibility with the current grease pencil features, vertex groups need to be supported.

Grease Pencil allows filtering by vertex group for modifiers.To support this, it also makes sense to have read/write access for vertex groups in the attributes API.

In the future, vertex groups should be just another custom attribute on meshes/curves/grease pencil. There are some more issues to be solved before that can happen. This step gets us a bit closer since the vertex weight data is stored in `CustomData`.

86a0d0015a VSE: Improve retiming UI
Currently retiming is quite awkward, when you need to retime multiple
strips strips in sync. It is possible to use meta strips, but this is
still not great. This is resolved by implementing selection.

General changes:
Gizmos are removed, since they are designed to operate only on active
strip and don't support selection.
Transform operator code is implemented for retiming data, which allows
more sophisticated manipulation.
Instead of drawing marker-like symbols, keyframes are drawn to
represent retiming data. Retiming handles are now called keys. To have
consistent names, DNA structures have been renamed.
Retiming data is drawn on strip as overlay.

UI changes:
Retiming tool is removed. To edit retiming data, press Ctrl + R, select
a key and move it. When retiming is edited, retiming menu and
context menu shows more relevant features, like making transitions.
Strip and retiming key selection can not be combined. It is possible to
use box select operator to select keys, if any key is selected.
Otherwise strips are selected.
Adding retiming keys is possible with I shortcut or from menu.
Retiming keys are always drawn at strip left and right boundary. These
keys do not really exist until they are selected. This is to simplify
retiming of strips that are resized. These keys are called "fake keys"
in code.

API changes:
Functions, properties and types related to retiming handles are renamed
to retiming keys:
retiming_handle_add() -> retiming_key_add()
retiming_handle_move() -> retiming_key_move()
retiming_handle_remove() -> retiming_key_remove()
retiming_handles -> retiming_keys
RetimingHandle -> RetimingKey

Retiming editing "mode" is activated by setting `Sequence.show_retiming_keys`.

ad169ba67a Geometry Nodes: support baking individual simulations
Previously, it was only possible to bake all simulations at once. This is great
for simple use-cases that, but in more complex setups one can have independent
simulations that should also be baked independently. This patch allows baking
individual simulation zones.

Furthermore, each simulation zone can now also have its own bake path and
simulation frame range. By default the simulation frame range is the scene frame
range, but it can also be customized on the scene or simulation zone level. The
bake path is generated based on the modifier bake path by default, but can be
set to another absolute or relative (to the .blend file) path.

The timeline drawing has been modified as well to be able to show more information
in the case when some simulations are baked and others are not. Instead of showing
a line for every simulation, it shows a condensed view of the important information
using at most two lines:
Is something baked? Is something valid or invalid? Also see #112232.

73460903fa Asset Shelf: Transparent asset shelf header with background for buttons
Draw the background of the asset shelf header fully transparent, with an opaque
background with rounded corners behind sections containing buttons. This
reduces the visual space consumed by the asset shelf, and makes the header
follow a tabbed folder metaphor better. Also, this works much better with our
click-through feature, where transparent parts of regions without buttons are
passed through the region under it (we might want to consider unifying code
here a bit).

The edge to drag for region resizing respects the transparent sections.
When there is little space between sections, the sections get merged so that
there are no small gaps in the bar.

Part of #107881.

Note that the core of this is implemented in a generic way, so this can be
reused for other regions.
