GPv3 stores the vertex group inside `CurvesGeometry`.
When the object level vertex group name is changed, we have to loop over
the vertex group list of each drawing. If a matching name is
found, copy the new name to the vertex group in `CurvesGeometry`. A separate
function is created to handle this: `BKE_grease_pencil_vgroup_name_update`.

the Depsgraph wasn't notified.
Fixed by tagging the owner ID of the fcurve modifier for an update.

Two issues were present in code that was resetting CRF quality level
to "do not use CRF, use bitrate settings" mode:
- It did not include AV1 codec, so whenever you switched to AV1 the CRF
was changing to constant bitrate.
- It wrongly included DNxHD codec. That seemed like it was trying to
fix#100079 in 06a01168f6, but it was doing exactly the opposite
of what a fix should have been? I don't understand it :/ In any case,
now with DNxHD removed the CRF properly switches to constant bitrate
when changing codec to DNxHD.
Factored the actual logic into BKE_ffmpeg_codec_supports_crf function.

This commit takes the 'Slotted Actions' out of the experimental phase.
As a result:
- All newly created Actions will be slotted Actions.
- Legacy Actions loaded from disk will be versioned to slotted Actions.
- The new Python API for slots, layers, strips, and channel bags is
available.
- The legacy Python API for accessing F-Curves and Action Groups is
still available, and will operate on the F-Curves/Groups for the first
slot only.
- Creating an Action by keying (via the UI, operators, or the
`rna_struct.keyframe_insert` function) will try and share Actions
between related data-blocks. See !126655 for more info about this.
- Assigning an Action to a data-block will auto-assign a suitable Action
Slot. The logic for this is described below. However, There are cases
where this does _not_ automatically assign a slot, and thus the Action
will effectively _not_ animate the data-block. Effort has been spent
to make Action selection work both reliably for Blender users as well
as keep the behaviour the same for Python scripts. Where these two
goals did not converge, reliability and understandability for users
was prioritised.
Auto-selection of the Action Slot upon assigning the Action works as
follows. The first rule to find a slot wins.
1. The data-block remembers the slot name that was last assigned. If the
newly assigned Action has a slot with that name, it is chosen.
2. If the Action has a slot with the same name as the data-block, it is
chosen.
3. If the Action has only one slot, and it has never been assigned to
anything, it is chosen.
4. If the Action is assigned to an NLA strip or an Action constraint,
and the Action has a single slot, and that slot has a suitable ID
type, it is chosen.
This last step is what I was referring to with "Where these two goals
did not converge, reliability and understandability for users was
prioritised." For regular Action assignments (like via the Action
selectors in the Properties editor) this rule doesn't apply, even though
with legacy Actions the final state ("it is animated by this Action")
differs from the final state with slotted Actions ("it has no slot so is
not animated"). This is done to support the following workflow:
- Create an Action by animating Cube.
- In order to animate Suzanne with that same Action, assign the Action
to Suzanne.
- Start keying Suzanne. This auto-creates and auto-assigns a new slot
for Suzanne.
If rule 4. above would apply in this case, the 2nd step would
automatically select the Cube slot for Suzanne as well, which would
immediately overwrite Suzanne's properties with the Cube animation.
Technically, this commit:
- removes the `WITH_ANIM_BAKLAVA` build flag,
- removes the `use_animation_baklava` experimental flag in preferences,
- updates the code to properly deal with the fact that empty Actions are
now always considered slotted/layered Actions (instead of that relying
on the user preference).
Note that 'slotted Actions' and 'layered Actions' are the exact same
thing, just focusing on different aspects (slot & layers) of the new
data model.
The "Baklava phase 1" assumptions are still asserted. This means that:
- an Action can have zero or one layer,
- that layer can have zero or one strip,
- that strip must be of type 'keyframe' and be infinite with zero
offset.
The code to handle legacy Actions is NOT removed in this commit. It will
be removed later. For now it's likely better to keep it around as
reference to the old behaviour in order to aid in some inevitable
bugfixing.
Ref: #120406
In the Action editor header, change the "Show All Slots" filter to
become "Only Show Slot of Active Object". The default state remains
"off".
This means that any new/upgraded Action editor will show all slots in
the Action by default. I think this is a good idea, especially since
cb6ed12ef1 makes related data-blocks share
the same Action, and thus the Action will have a mixture of Object and
non-Object animation. I suspect that it'll help in understanding the new
functionality of slotted Actions when they are most visible, i.e. when
the multiple slots are all shown.
Since slotted Actions are so new, I don't think we need to add
versioning code to accomodate this change.

Like with NLA strips, Action assignment on Action Constraints needs to
have an extra step (compared to regular assignment to animated
data-blocks).
For the Action Constraint, the auto slot selection gets one more
fallback option (compared to the generic code). This is to support the
following scenario, which used to be necessary as a workaround for a bug
in Blender (#127976):
- Python script creates an Action,
- assigns it to the animated object,
- unassigns it from that object,
- and assigns it to the object's Action Constraint.
The generic code doesn't work for this. The first assignment would see
the slot `XXSlot`, and because it has never been used, just use it. This
would change its name to `OBSlot`. The assignment to the Action
Constraint would not see a 'virgin' slot, and thus not auto-select
`OBSlot`. This behaviour makes sense when assigning Actions in the
Action editor (it shouldn't automatically pick the first slot of
matching ID type), but for the Action Constraint I (Sybren) feel that it
could be a bit more 'enthousiastic' in auto-picking a slot.
Note that this is the same behaviour as for NLA strips, albeit for a
slightly different reason. Because of that it's not sharing code with
the NLA.
Pull Request: https://projects.blender.org/blender/blender/pulls/128892
When creating a new NLA strip for an action, as well as when setting
`strip.action` via RNA, use the generic action-assignment code. This
ensures that the slot selection follows the same logic as other Action
assignments.
If the generic slot selection doesn't find a suitable slot, and there is
a single slot on that Action of a suitable ID type, always assign it.
This is to support the following scenario:
- Python script creates an Action and adds F-Curves via the legacy API.
- This creates a slot 'XXSlot'.
- The script creates multiple NLA strips for that Action.
- The desired result is that these strips get the same Slot assigned as
well.
The generic code doesn't work for this, because:
- The first strip assignment would see the slot `XXSlot` (`XX`
indicating "not bound to any ID type yet"). Because that slot has
never been used, it will be assigned (which is good). This assignment
would change its name to, for example, `OBSlot`.
- The second strip assignment would not see a 'virgin' slot, and thus
not auto-select `OBSlot`. This behaviour makes sense when assigning
Actions in the Action editor (assigning an Action that already
animates 'Cube' to 'Suzanne' should not assign the 'OBCube' slot to
Suzanne), but for the NLA I feel that it could be a bit more
'enthousiastic' in auto-picking a slot to support the above case.
This is preparation for the removal of the 'Slotted Actions'
experimental flag, and getting the new code to run as compatibly as
possible with the legacy code.
The return value of `animrig::nla::assign_action()` has changed a bit.
It used to indicate whether a slot was auto-selected; it now indicates
whether the Action assignment was successful. Whether a slot was
assigned or not can be seen at `strip.action_slot`.

Split the legacy Action handling code of `action_fcurve_ensure()` into a
new function `action_fcurve_ensure_legacy()`. This makes it possible for
unit tests to explicitly create a legacy Action for testing, regardless
of the 'Slotted Actions' experimental feature flag.
When we drop that flag, the unit tests that explicitly test legacy
behaviour will keep running.

Part of the brush assets project followups, see #116337.
Based on feedback, it seems important to indicate to the user when a brush has
unsaved changes.
There's no reliable updating mechanism we can use or hook into here, except for
RNA "update" callbacks. Brush data gets changed in many places in code, the only
way to do this seems manual tagging every time a brush property gets changed.
This PR introduces `BKE_brush_tag_unsaved_changes()` for this. I spent some time
going through all brush properties to ensure changes call the tagging function.
A known limitation with this will be that changes to dependencies won't be
indicated in the brush. E.g. Changing the texture attached to a brush won't make
the brush be indicated as changed.
The UI to indicate the changed brushes is being discussed still, see #128846.

Print in `RNA_struct_free` would crash in ASAN builds because they can often
access memory (struct identifier) that is owned by Python/BPY, and
therefore already freed at exit time.
Change the `Action.id_root` RNA definition such that
`Action.bl_rna.properties["id_root"].enum_items` returns all valid
values for that property. This was the Blender 4.2 (and older) behaviour
as well.
The only difference now is that v4.3 adds a new `UNSPECIFIED` enum item,
which is not a valid ID type, but is a valid value for `Action.id_root`.
Some more context:
In Blender 4.2 the `Action.id_root` property was a hard-coded list of
all ID types. To add the `UNSPECIFIED` item in v4.3, this was replaced
by an 'items' callback. The way Blender deals with this by default is
such that querying `Action.bl_rna.properties["id_root"].enum_items`
returns its hard-coded default list, and not the result of that 'items'
callback function.
For Action Slots (which will be released in v4.4 but are already in the
sources as experimental feature), there is a similar property that is
implemented in a way such that its `.enum_items` always returns the
proper list. This commit updates the `Action.id_root` RNA property
definition so that it shares code with `ActionSlot.id_root`, fixing the
reported issue.
Note that the `ActionSlot` type is not exposed to RNA in Blender 4.3,
it's just some internal code that is now shared.

OpenEXR has many compression codecs exposed, with some of them arguably
not very useful. Generally, for lossless compression you want ZIP or PIZ,
and for lossy compression you want DWAA/DWAB. Reorder the dropdown
entries so that these are at the top just below "No compression".
Previously the not-really-great choice of Pxr24 was the first.
Add tooltips to all the compression codecs too, trying to explain
what each of them does in once sentence.
Remove "(lossless)" labels and keep only "(lossy)" -- this is much easier
to visually parse, since both of them were very similar to each other before.

Removes unused GPv2 functions in blenkernel.
Notes:
- Functions for layer masks are still in use, but annotations never
have layer masks in the first place. Would be good to remove the data
structures so we can remove the functions too.
- Some multi-frame edit functions are also still nominally used, but
multi-frame editing is not an active feature for annotations. This
should also be removed.

Previously, alignment did exist, but it only changed whole text block
position in relation to a fixed point. This was later renamed to "Anchor".
Now it correctly aligns each line of text. Alignment works with newline
character and word wrapping.
Currently newline characters can't be entered directly, but this should
be resolved soon.
To keep existing anchoring feature, new DNA fields are added and
values from old alignment are copied there.
This PR is part of bigger change [1], and originally I expected to
implement this feature at later stage. But the design called for drawing
text character by character, which would mean, that I would have to
rewrite text alignment anyway.
To render the text, a struct is built, where position and width of each
character is stored. In addition, width of each line is stored. This allows
to implement proper text alignment feature, instead of existing
anchoring. Text is then drawn character by character in a loop.
There are some small differences in text rendering, since this is only
approximation of how BLF library draws glyphs, but it is very close.
For text bounbox, `BLF_boundbox()` is used on per line basis,
because some fonts do not use their full height and this information
is not available on VSE side.

The `pre` handler is called after blender internal code is done populating
the link/append context with data to be processed, and before this data
starts being linked from library files.
The `post` handler is called after blender is done linking, and
potentailly appending and/or instantiating, the requested data and all
of their dependencies.
Both handlers are called with a single argument, the link/append
context.
An new RNA sets of wrappers have been added to expose relevant info from
these internal C++ structures.
NOTE: !113658 is very similar (but tied to asset drag & drop), whereas
this PR is more general (these could probably live hand-in-hand / side-

Previously, Cycles only supported the Henyey-Greenstein phase function for volume scattering.
While HG is flexible and works for a wide range of effects, sometimes a more physically accurate
phase function may be needed for realism.
Therefore, this adds three new phase functions to the code:
Rayleigh: For particles with a size below the wavelength of light, mostly athmospheric scattering.
Fournier-Forand: For realistic underwater scattering.
Draine: Fairly specific on its own (mostly for interstellar dust), but useful for the next entry.
Mie: Approximates Mie scattering in water droplets using a mix of Draine and HG phase functions.
These phase functions can be combined using Mix nodes as usual.
