This adds `char *simulation_bake_directory` to the nodes modifier. The path is automatically generated the first time the modifier is baked. It is _not_ automatically changed afterwards. The path is relative to the .blend file by default. For now, the path is not exposed in the UI or Python API.
This fixes issues where renaming objects/modifiers can cause the baked data to not work anymore.

Before 9f78530d80, the -1 coarse_edge_index values in the
foreach_edge calls would return false in BLI_BITMAP_TEST_BOOL,
which made them look like loose edges. BitSpan doesn't have this
problem, so the return for negative indices must be explicit.
Some `ImagePartialUpdateTest` test are calling code that needs access to
a valid `G_MAIN`. So store the generated main there as part of the setup
step, and reset G_MAIN to its original value (should be NULL) in the
teardown step.
NOTE: Things like `ID_BLEND_PATH_FROM_GLOBAL` and
`BKE_main_blendfile_path_from_global` are pure evil. It may be necessary
in a very few small cases, but their current usages need a lot of strong
cleanup.

The usual special ShapeKey case needs yet another extra corner case
special handling... See comments in code for details about that specific
issue.
NOTE: May be worth checking if this can be backported to 3.3 LTS too.
Mark `NlaStrip.frame_{start,end}` and `NlaStrip.frame_{start,end}_ui` as
to-be-ignored for the library override system, and add a new set of RNA
properties `frame_{start,end}_raw` that the library override system can
use.
Versioning code ensures that overrides on `frame_{start,end}` are
altered to be applied to the `..._raw` counterpart instead.
The override system uses RNA to update properties one-by-one, and the
RNA code trying its best to keep things consistent / valid. This is very
much desired behaviour while a human is editing the data.
However, when the library override system is doing this, it is not
replaying the individual steps (that each end in a valid configuration),
but just setting each property one by one. As a result, the intermediate
state can be invalid (for example moving one strip into another) even
when the end result is perfectly fine.
This is what the `..._raw` properties do -- they set the values without
doing any validation, so they allow the library overrides system to move
strips around.
This assumes that the result of the override is still valid. Logic to
detect invalid situations, and reshuffle the NLA strips if necessary, is
left for a future commit as it is related to #107990 (NLA Vertical
Reorder).
Additionally, this commit adds functions
`BKE_lib_override_library_property_rna_path_change()` and
`BKE_lib_override_library_property_search_and_delete()` to the library
override API. The former is used to change RNA paths of property
overrides, and the latter is used to remove a property override
identified by its RNA path.
Add a ensure_utf8 argument to WM_clipboard_text_get so callers don't
have to handle validation themselves.
Copying non-utf8 text into the Python console and buttons was possible,
causing invalid cursor position and a UnicodeDecodeError accessing
ConsoleLine.body from Python.
This function handles cleaning valid system paths that are functional
when passed to `open(..)` but may be relative to the current working
directory or have redundant slashers that can be normalized.
This feature implements smooth transition between 2 retimed segments.
A transition can be added by dragging retiming handle while holding
shift key. When any handle defining transition is removed, the
transition segment is removed and 2 linear segments are restored to
state before transition was created.
These transitions work with video and sound and changes are reflected
in waveforms with correct seeking, therefore it replaces usage of
`speed_factor` or earlier sound `pitch` property.
Smooth transition is achieved by evaluating Y value of circular arc,
that is tangent to lines of linear retimed segments. Because of this,
when transition length is changed both handles are moved symetrically.
This way it is possible to make transition without affecting content in
linear segments.
When linear segment after transition is further retimed, this shifts
content inside of a transition segment.
To support sound, `SEQ_retiming_sound_animation_data_set` and related
data structures has been updated to build speed table for each smooth
transition segment. Layering of retiming data via meta strips is still
fully supported.

This commit adds a new experimental node "Sample Volume".
It's purpose is to be able to sample values from a volume grid given
a position field.
The 'Grid' input accepts a named attribute input with the name
of the volume grid to sample. Values will be implicitly converted
from the grid type to the specified value type.

Internal private struct was using `owner_id`/`self_id`, while the public
callback data struct was using `id_owner`/`id_self`.
Now using internal naming everywhere in lib_query related code, as
`owner_id` is already used in very low-level 'fundamental' part of the
code, e.g. in the `PointerRNA` struct, or in ID's 'loopback' pointers
for embedded data.
Note that this is only a very small first step toward proper naming
consistency for these type of data, the mismatch is currently spread all
over the code base.
We also need to document more formally the meaning and differences
between `self` and `owner` here.
Using the topology map gives a constant time lookup, since it has a map
of nodes per type. The collada code used the old function, but had been
ifdef'd for four years, so it's removed here.
Functions were moved as part of f7388e3be5, which was
unnecessarily noisy. Instead of reverting, move the definitions back
to their original place in node.cc. Also move a few more things to
the blender::bke namespace.
Since a generic snap cursor was implemented (which can be used by Tools and by DragDrop), the Placement Settings are no longer a settings of the "VIEW3D_OT_interactive_add" Operator.
With that implementation, those properties started to be defined in a
static struct, filled in at runtime and accessed in the UI through
workarrounds.
As they are properties initialized at runtime, they are not saved in
the file.
The solution is to move the Placement Settings to `ToolSettings`.

Include the term "overwrite" so users of this function are aware
this function will delete the destination file (unlike LIBC rename).
- Add BLI_rename_overwrite (previously called BLI_rename).
- BLI_rename is now a wrapper for rename.
Use BLI_rename when renaming in the file selector.
See: https://projects.blender.org/blender/blender/issues/103343
Changes:
1. Added `BKE_node.hh` file. New file includes old one.
2. Functions moved to new file. Redundant `(void)`, `struct` are removed.
3. All cpp includes replaced from `.h` on `.hh`.
4. Everything in `BKE_node.hh` is on `blender::bke` namespace.
5. All implementation functions moved in namespace.
6. Function names (`BKE_node_*`) changed to `blender::bke::node_*`.
7. `eNodeSizePreset` now is a class, with renamed items.

The issue was that in case an ID was only related to its liboverride
hierarchy through a 'to' pointer (e.g. the parent pointer of an object),
it would now be tagged as 'isolated' from its hierarchy, since nothing
in said hierarchy actually points to it. It would then be deleted during
resync process.
This is once again the infamous 'inverted dependency logic of object
parenting' case...
Note that this did not have any consequences on typical liboverride
usages (based on using a hierarchy of collections0, since all objects
would then be referenced by one or more collection.
Reported by @dr.sybren while investigating #102662.
Add a new flag that determines whether root bones (i.e. bones without a
parent) should be translated to the armature object's origin. This can
be found in the Armature's IK properties panel.
By default this flag is disabled, so new rigs will not see this 'locking
to the origin' behaviour. Versioning code ensures that the flag is
enabled on older files, to preserve the behaviour of existing rigs.
This also bumps the Blender subversion and at the same time fixes an
incorrect bump in ee08b2ddff (where the
'minimum compatible version' was updated instead of the current Blender
version).

GCC documented FILENAME_MAX is the maximum length of a file that can
be opened, not to be used for allocation as it may be INT_MAX for e.g.
Even though this wasn't the case on supported systems,
prefer FILE_MAX which is used for full paths in most places.
Making the custom data API const correct in 3a3d9488a1 caused
the issue, because it previously relied on non-threadsafe behavior. As a
workaround, just restore the thread-unsafety, and note the issue in a
new comment.
There was even one case in BLI ListBase tests!
Order was opposite of the one expected by the BLI ListBase code... Not
sure how, but this did not cause any issue apparently? But would expect
it to at least affect the order in which items in the list would be
iterated.
`BKE_library_id_can_use_filter_id` would not handle properly cases where
the ID is a liboverride - it's hierarchy root pointer can point back to
virtually any kind of ID (although typically a Collection or Object).
This was breaking liboverride resync process in some rare cases, by
failing to remap the 'hierarchy root' pointer of some liboverrides.
This makes the Blender binary 350 KB smaller. The largest change comes
from using `FunctionRef` instead of a template when gathering indices to
mix in the extrude node (which has no performance cost). The rest of the
change comes from consolidating uses of code generation for all
attribute types. This brings us a bit further in the direction of
unifying attribute propagation.

Adds an input node Signed Distance that can
be used to refer to the distance-grid of an SDF volume.
Right now it's experimental and can be enabled by enabling
"New Volume Nodes" in the preferences.
It returns a float AttributeFieldInput called 'distance' which
can tell Volume nodes which grid to get.
See #103248.
LibOverride resync process would not properly 'make local' newly created
overrides (copied from their linked reference). The main consequence was
that some linked data used by these new liboverrides would not be
properly tagged as directly linked.
While this would not be an issue in current codebase, this was breaking
upcomming readfile undo refactor, since some linked data did not get
their local 'placeholder reference' data written in memfile blendfiles.
NOTE: this is more of a quick fix, whole handling of library data in
complex copying cases like that need some more general work, see #107848
and #107847.
Issue was that, when UI-related code _is_ requested in foreach_id
processing, `ID_SCR` screen ID type can actually use any kind of ID
(through e.g. the Outliner space).
So `BKE_library_id_can_use_filter_id` had to be updated with a new
parameter (whether UI-related data should be taken into account or not).
The root of the issue was that while reading a new blendfile, the
current `G_MAIN` is still the old one, not the one in which new data is
being read.
Since the remapping callback taking care of UI data during ID remapping
is using `G_MAIN`, it is processing the wrong data, so when deleting the
invalid shapekey (from `BLO_main_validate_shapekeys`), the UI data of
the new bmain would not be properly remapped, causing invalid memory
access later when recomputing user counts (calls to
`BKE_main_id_refcount_recompute`).
This is fixed by adding a new `BKE_id_delete_ex` function that takes
extra remapping options parameter, and calling it from
`BLO_main_validate_shapekeys` with extra option to enforce handling of
UI data by remapping code.
NOTE: At some point we have to check if that whole UI-callback thing is
still needed, would be good to get rid of it and systematically process
UI-related ID pointers like any others. Current situation is... fragile
to say the least.
For realtime use cases, storing the geometry's state in memory at every
frame can be prohibitively expensive. This commit adds an option to
disable the caching, stored per object and accessible in the baking
panel. The default is still to enable caching.

Caused by 2fb31f34af.
Since above commit, we are now calling `BKE_mesh_orco_verts_transform`
not only from `psys_face_mat` and `psys_mat_hair_to_orco`, but now also
from `psys_particle_on_dm` > `psys_interpolate_face`, so we get double
transforms with mirror.
Remove the "extra" call in `psys_mat_hair_to_orco`.
Should be backported to 3.3 LTS as well.
