This refactors how a geometry nodes node tree is converted to a lazy-function
graph. Previously, all nodes were inserted into a single graph. This was fine
because every node was evaluated at most once per node group evaluation.
However, loops (#108896) break this assumption since now nodes may be
evaluated multiple times and thus a single flat graph does not work anymore.
Now, a separate lazy-function is build for every zone which gives us much
more flexibility for what can happen in a zone. Right now, the change only
applies to simulation zones since that's the only kind of zone we have.
Technically, those zones could be inlined, but turning them into a separate
lazy-function also does not hurt and makes it possible to test this refactor
without implementing loops first. Also, having them as separate functions
might help in the future if we integrate a substep loop directly into the
simulation zone.
The most tricky part here is to just link everything up correctly, especially
with respect to deterministic anonymous attribute lifetimes. Fortunately,
correctness can be checked visually by looking at the generated graphs.
The logging/viewer system also had to be refactored a bit, because now there
can be multiple different `ComputeContext` in a single node tree. Each zone
is in a separate `ComputeContext`. To make it work, the `ViewerPath` system
now explicitly supports zones and drawing code will look up the right logger
for showing inspection data.
No functional changes are expected, except that the spreadsheet now shows
"Simulation Zone" in the context path if the viewer is in a simulation.
The default value of the "sharp_face" attribute is False like other
boolean attributes. That mistakenly changed behavior in addons
that created meshes with `Mesh.from_pydata`. To fix, add an
argument with a default value that maintains the behavior
from before, and add convenience, `shade_smooth` and
`shade_flat` methods.
This patch adds support for two of the three selection domains in the Edit Mode tool settings: point and stroke.
Affected selection operators: select all, lasso select, select pick, box select.

Add a quaternion rotation socket type, and using the recently added
rotation attribute type, support the type in most of the multi-type
geometry nodes, and modifier attribute inputs and outputs.
The socket is still exposed with an XYZ Euler default value.
In the future we can add modes to this rotation value similar
to object rotations.
Rotation values have no implicit conversions to other types.
Nodes to convert to and from rotation values will be added
in a follow-up commit.
For now, the new socket type is hidden behind and experimental
option, because we haven't chosen the final color for it yet.

Adds an optional list of panels to node trees. Each socket can be
assigned a panel. UI panels will be created in the future in the
modifier for these grouped sockets.
Panels are stored as a pointer array in node trees, next to socket
declarations. Each panel has a name, but it does not have to be unique.
In future a panel might also store whether it is visible by default and
similar information.
C API and RNA API are both added. Panels and their socket
assignments are accessible to users through another list in the "Group"
tab of the node editor sidebar.
Sockets in the same panel will remain together even when adding,
removing, or moving sockets or panels, renaming, etc.
A socket can be moved up or down within a panel but each panel
remains a contiguous block. Actual tree views may be created later.

Store subdivision surface creases in two new named float attributes:
- `crease_vert`
- `crease_edge`
This is similar to 2a56403cb0.
The attributes are naming conventions, so their data type and domain
aren't enforced, and may be interpolated when necessary. Editing tools
and the subdivision surface modifier use the hard-coded name. It might
be best if these were edited as generic attributes in the future, but
in the meantime using generic attributes helps.
The attributes are visible in the list, which is how they're now meant
to be removed. They are now interchangeable with any tool that works
with the generic attribute system-- even tools like vertex paint can
affect creases now.
This is a breaking change. Forward compatibility isn't preserved for
versions before 3.6, and the `crease` property in RNA is removed in
favor of making a smaller API surface area with just the attribute API.
`Mesh.vertex_creases` and `Mesh.edge_creases` now just return the
matching attribute if possible, and are now implemented in Python.
New functions `*ensure` and `*remove` also replace the operators to
add and remove the layers for Python.
A few extrude node test files have to be updated because of different
(now generic) attribute interpolation behavior.

No user visible changes expected.
Needed for the asset shelf (#102879).
Adds a UI operator triggered on Ctrl+F that will attempt to start
filtering for the hovered UI view, typically enabling a filter text
button.
View items can implement their own filter method, there's no default
one. Maybe we should add default or re-usable string filtering method
though.
Filtering is applied after constructing the view and filtered out (as
in, invisible) items are kept in storage, so that their state
(selection, active, etc.) is preserved. The filtered state is cached in
the item, so this is only done once per redraw.
Caused by 5ca65001ea (which was already patched with ae7c71ef09 and
fa5cc84a0a)
Getting the right modifier would still fail / throw errors when not done
from the modifier extra ops dropdown.
Only there, a 'modifier' attribute is set for context (via
`uiLayoutSetContextPointer` in `modifier_ops_extra_draw`).
So now check if a 'modifier' attribute is set for context (and fallback
to using the active modifier instead).
This way, polling errors in F3 search are gone and you can actually
execute the operators which are also in modifier extra ops dropdown from
elsewhere (e.g. F3 search).

Face maps were added as a prototype of a new rigging solution during
2.8 development. Their storage is redundant with the newer generic
attribute system (specifically with integer face attributes), and
they were never used much. This commit removes the face map list
and converts the storage to an attribute with the name `face_maps`.
There is nowhere to store the face map names anymore, so those
are not kept.
It probably still makes sense to have a feature like mesh face gizmo
selection for rigging. But the design and implementation woulds likely
have to change significantly, including possibly changing the storage
type, and making use of the generic attribute system instead of a
special type.
See #105317 for more discussion.
The RNA function `FCurve.update()` now also deduplicates keys. This is done
in a way that is independent of key selection; simply the last key in the
list of keyframes 'wins' and overwrites earlier ones. It is exactly the
same as `FCurve.keyframe_points.deduplicate()`.
The filter is used to reduce noise while preserving edges. It can be used to create a cartoon effect from photorealistic images.
It offers two variations:
1) Classic aka isotropic kuwahara filter: simple and faster computation. Algorithm splits an area around a single pixel in four parts and computes the mean of the region with the lowest standard deviation.
2) Anisotropic Kuwahara filter: improves the classical approach by considering the direction of structures of regions
This patch implements both approaches above as multi-threaded operations for the full-frame and tiled compositor.

The graph editor has the function to hide the display of FCurves and to only draw keyframes on selected curves.
Both options were not respected when executing the frame jump operator,
meaning it would jump to potentially hidden keyframes.
This patch adds a new operator that is specific to the Graph Editor and that respects those features.
The only possible issue that could arise from this is a slight confusion for the user
why they behave differently between editors.
Especially with only the Graph Editor and the 3D view open.
In general I think it's an improvement and follows the "you can only modify what you see" mantra in blender

This implements the `VIEW3D_OT_select_box` for the new grease pencil data-block.
Note that this also adds a `get_evaluated_grease_pencil_drawing_deformation` function, but there are TODOs left.
This will have to be updated once the modifier logic is in place.
