Add an option to output curves as NURBS instead of Bezier. The same
fitting algorithms are used. The only difference is that the drawing
result is a NURBS curve with Bezier knot mode, instead of a native
Blender Bezier curve.

As discussed in #105407, it can be useful to support returning
a fallback value specified by the user instead of failing the driver
if a driver variable cannot resolve its RNA path. This especially
applies to context variables referencing custom properties, since
when the object with the driver is linked into another scene, the
custom property can easily not exist there.
This patch adds an optional fallback value setting to properties
based on RNA path (including ordinary Single Property variables
due to shared code and similarity). When enabled, RNA path lookup
failures (including invalid array index) cause the fallback value
to be used instead of marking the driver invalid.
A flag is added to track when this happens for UI use. It is
also exposed to python for lint type scripts.
When the fallback value is used, the input field containing
the property RNA path that failed to resolve is highlighted in red
(identically to the case without a fallback), and the driver
can be included in the With Errors filter of the Drivers editor.
However, the channel name is not underlined in red, because
the driver as a whole evaluates successfully.

This adds option to bypass the raytracing pipeline
entirely and use a cheaper evaluation option.
This reuse the same evaluation as the Blended materials.
This exhibits some artifacts on Apple hardware due to

Make it possible to nest bone collections. The data structure on the
armature is still a flat array. It is organised as follows:
- Sibling collections (i.e. ones with the same parent) are stored
sequentially in the array.
- Each bone collection keep track of the number of children, and the
index of the first child.
- Root collections (i.e. ones without parent) are stored as the first
elements in the array.
- The number of root collections is stored on the Armature.
This commit also contains the following:
- Replaced the flat UIList of bone collections with a tree view.
- Updated the M/Shift+M operators (move/assign to collection) to work
with hierarchical bone collections.
- Updated RNA interface to expose only root collections at
`armature.collections`. All collections are available on
`armature.collections.all`, and children at `bonecollection.children`.
- Library override support. Only new roots + their subtrees can be added
via overrides.

Combination of two operators by Ares Deveaux
#106524 and #106523
Introduces a new operator "Scale from Neighbor"
that scales selected keyframe segments from either
the left or right keyframe neighbor.
Pressing "D" during modal operation will switch
from which end of the segment the scaling happens.
This is useful to make a section of animation closer to a pose on either side.

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.

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.

Previously, attribute values were only visualized as color overlay in the 3d viewport.
Now it's possible to optionally show the attribute values as text. This can be enabled
in the `Viewer Node` overlay settings in the 3d view.
This is just the first initial version. More work towards making it look better
will be done next.

Split the `armature.collection_assign` operator in two. Before, the
operator could do two things: assign selected bones to the active/named
bone collection, or create a new bone collection with the given name.
This is now split up, where `armature.collection_assign` only assigns to
existing bone collections, and `armature.collection_create_and_assign`
always creates a new bone collection.
This makes the purpose of each operator clearer & more predictable.
This adds a new `Bake` node which allows saving and loading intermediate geometries.
Typical use cases we want address with this currently are:
* Bake some data for use with a render engine.
* Bake parts of the node tree explicitly for better performance.
For now, the format that is written to disk is not considered to be an import/export format.
It's not guaranteed that data written with one Blender version can be read by another
Blender version. For that it's better to use proper interchange formats. Better support for
those will be added eventually as well. We also plan an `Import Bake` node that allows
reading the blender-specific baked data independent of the Bake node and at different frames.
The baking works very similar to the baking in the simulation zone (UI and implementation
wise). Major differences are:
* The Bake node has a `Bake Still` and `Bake Animation` mode.
* The Bake node doesn't do automatic caching.
Implementation details:
* Refactored how we create the Python operators for moving socket items so that it also
makes sense for non-zones.
* The `ModifierCache` stores an independent map of `SimulationNodeCache` and
`BakeNodeCache`, but both share a common data structure for the actually baked data.
* For baking, the `Bake` node is added as a side-effect-node in the modifier. This will make
sure that the node is baked even if it's currently not connected to the output.
* Had to add a new `DEG_id_tag_update_for_side_effect_request` function that is used
during baking. It's necessary because I want to evaluate the object again even though none
of its inputs changed. The reevaluation is necessary to create the baked data. Using
`DEG_id_tag_update` technically works as well, but has the problem that it also uses the
`DEG_UPDATE_SOURCE_USER_EDIT` flag which (rightly) invalidates simulation caches
which shouldn't happen here.
* Slightly refactored the timeline drawing so that it can also show the baked ranges of
Bake nodes. It does not show anything for baked nodes with a in Still mode though.
* The bake operator is refactored to bake a list of `NodeBakeRequest` which makes the
code easier to follow compared to the previous nested
`ObjectBakeData > ModifierBakeData > NodeBakeData` data structure.
* The bake operators are disabled when the .blend file is not yet saved. This is technically
only necessary when the bake path depends on the .blend file path but seems ok to force
the user anyway (otherwise the bake path may be lost as well if it's set explicitly).
* The same operators are used to bake and delete single bakes in `Bake` nodes and
`Simulation Zones`. On top of that, there are separate operators of baking and deleting all
simulation bakes (those ignore bake nodes).
* The `Bake` node remembers which inputs have been fields and thus may be baked as attributes.
For that it uses an `Is Attribute` flag on the socket item. This is needed because the baked data
may still contain attribute data, even if the inputs to the bake node are disconnected.
* Similar to simulation zones, the behavior of `Bake` nodes is passed into the geometry nodes
evaluation from the outside (from the modifier only currently). This is done by providing the
new `GeoNodesBakeParams` in `GeoNodesCallData` when executing geometry nodes.
Next Steps (mostly because they also involve simulations):
* Visualize nodes that have not been evaluated in the last evaluation.
* Fix issue with seemingly loosing baked data after undo.
* Improve error handling when baked data is not found.
* Show bake node in link drag search.
* Higher level tools for managing bakes.

Before #108014, toggling "Auto Smooth" was an easy way to disable
evaluation of custom normals and face corner normals for faster
viewport playback performance. Now that corner normals are calculated
automatically as necessary, it's helpful to still have a way to disable
expensive normal computation for faster playback.
This commit adds a "Normals" scene simplify setting. To avoid a bunch
of complexity, it just influences which normals are requested from the
object by viewport rendering. In my tests, skipping calculating at
least doubled viewport FPS in a few test files with a large mesh with
custom normals. This works well because normals are cached and lazily
calculated.

This is a replacement for the workflow that uses
"Bake Curve" and "Unbake Curve" to quickly generate
dense key data.
Compared to the existing workflow it has the advantage
of allowing the user more control over the key types,
and distance between keys, as well as the frame range affected.
Operator options
* Range: the range that will be baked.
Defaults to the scene range or preview range.
* Step: Distance between keyframes.
Can be used to bake on 2s or even bake to subframes.
* Remove Existing Keys: Boolean option that
if enabled also removes keys outside the specified baking range
* Interpolation Type: Choose a interpolation mode used
for new keys e.g. Constant or Bezier
* Bake Modifiers: If enabled bakes the effect of the
modifier stack to keys and deletes the modifier stack.
If false, the code disables the modifiers before baking,
so the resulting keys will behave as if the modifiers didn't exist
The operator can be found in the Graph Editor under `Channel->Bake Channels`

Due to lack of forward compatibility, tool_settings.snap_uv_element
could return empty if a 4.0 file is opened in 3.6.
This causes a Python error when trying to identify the element's icon.
Avoid this python error.
This adds a new "Active Camera" input geometry node, per #105761.
The node outputs the the scene's current active camera. It is available
from Input > Scene > Active Camera in the geometry nodes Add menu.
Typical usage would be to connect this node to an Object Info node to
obtain its transform. This works as expected when the camera's
transform is animated, and also when there are markers on the timeline
that change the active camera.
In order to support the aforementioned changes in the active camera,
this implementation adds depsgraph relations for all cameras referenced
by timeline markers. This eliminates the complexity of updating the
depsgraph whenever the scene switches to a different active camera,
but of course it comes at the cost of including more objects than
strictly necessary in the depsgraph for scenes that switch cameras.
Dynamically updating the depsgraph upon camera changes could be a
future improvement if there proves to be sufficient need for it.

Adds new curves support to "Draw Curve" operator. This is a direct copy
and replace of the old code to the new editors directly, with a change to
create the new data structure instead of the old one. There is no attempt
at code deduplication, since that would complicate removing the old
curve type when it comes time.
To replace the "2D curve" option a new operator property is added
for projecting to the Z=0 plane.

This de-duplicate some passes in the raytracing
pipeline and make it more ready for adoption
of arbitrary closure evaluation. This last part
means the removal of some per closure type
options.
The put in common the tile classification step
that is now done only once for all 3 closure
type. Also add some speedup to the tile
compaction phase that is now only twice
faster.
The horizon-scan setup was also de-duplicated
and run only if needed, which can save up to
0.5ms is complex scenes.
However, this moves the max-roughness and and
resolution scaling to a common parameter.
This is to be able to support arbitrary closure
evaluation where multiple closure with conflicting
parameters could be evaluated in one tracing pass.

Remove "Invert Visible" from the face sets menu, since those concepts
are no longer tied together, except for some convenience features to
toggle visibility of some face sets.
On the code side, the `SCULPT_OT_face_set_invert_visibility` operator
is replaced by `PAINT_OT_visibility_invert`. It inverts vertex visibility
instead of face visibility, which mostly has the same results, except
for multires sculpting where it no longer "downgrades" visibility to
base mesh faces.
This PR adds the drawing placement modes from GPv2.
The drawing placement defines the depth (origin, view, surface, etc.) and a plane (view, cursor, xz, etc.).
This introduces a new helper class `DrawingPlacement` that does all of the internals to find the correct projection and just exposes a simple function to project from screen space to the drawing plane/surface.
Note: Drawing on other strokes currently doesn't work, because GPv3 can't be rendered to image yet. We use the depth buffer of the grease pencil render result to find the right depth.
