This commit renames enums related the "Curve" object type and ID type
to add `_LEGACY` to the end. The idea is to make our aspirations clearer
in the code and to avoid ambiguities between `CURVE` and `CURVES`.
Ref T95355
To summarize for the record, the plans are:
- In the short/medium term, replace the `Curve` object data type with
`Curves`
- In the longer term (no immediate plans), use a proper data block for
3D text and surfaces.

This change will make handling of liboverrides hierarchies (especially
resyncing) much easier and efficient. It should also make it more
resilient to 'degenerate' cases, and allow proper support of things like
parenting an override to another override of the same linked data (e.g.
a override character parented to another override of the same
character).
NOTE: this commit only implements minimal changes to add that data and
generate it for existing files on load. Actual refactor of resync code
to take advantage of this new info will happen separately.
Based on discussions from T95355 and T94193, the plan is to use
the name "Curves" to describe the data-block container for multiple
curves. Eventually this will replace the existing "Curve" data-block.
However, it will be a while before the curve data-block can be replaced
so in order to distinguish the two curve types in the UI, "Hair Curves"
will be used, but eventually changed back to "Curves".
This patch renames "hair-related" files, functions, types, and variable
names to this convention. A deep rename is preferred to keep code
consistent and to avoid any "hair" terminology from leaking, since the
new data-block is meant for all curve types, not just hair use cases.
The downside of this naming is that the difference between "Curve"
and "Curves" has become important. That was considered during
design discussons and deemed acceptable, especially given the
non-permanent nature of the somewhat common conflict.
Some points of interest:
- All DNA compatibility is lost, just like rBf59767ff9729.
- I renamed `ID_HA` to `ID_CV` so there is no complete mismatch.
- `hair_curves` is used where necessary to distinguish from the
existing "curves" plural.
- I didn't rename any of the cycles/rendering code function names,
since that is also used by the old hair particle system.

Previously, nearest interpolation filter was used for preview, because
it offered good performance and bilinear was used for rendering. This
is not always desirable behavior, so filter method can now be chosen by

This patch refactors the "Hair" data-block, which will soon be renamed
to "Curves". The larger change is switching from an array of `HairCurve`
to find indices in the points array to simply storing an array of offsets.
Using a single integer instead of two halves the amount of memory for that
particular array.
Besides that, there are some other changes in this patch:
- Split the data-structure to a separate `CurveGeometry`
DNA struct so it is usable for grease pencil too.
- Update naming to be more aligned with newer code and the style guide.
- Add direct access to some arrays in RNA
-- Radius is now retrieved as a regular attribute in Cycles.
-- `HairPoint` has been renamed to `CurvePoint`
-- `HairCurve` has been renamed to `CurveSlice`
- Add comments to the struct in DNA.
The next steps are renaming `Hair` -> `Curves`, and adding support
for other curve types: Bezier, Poly, and NURBS.

`BKE_collection_object_add` ensures given object is added to an editable
collection, and not e.g. a linked or override one.
However, some processes like do_version manipulate collections also from
libraries, i.e. linked collections, in those cases we need a version of
the code that unconditionnally adds the given object to the given
colleciton.
This is from patch D13988. It removes the "- New" from the menu of the
new obj exporter, changes the default addon to just io_import_obj,
and does the right versioning thing.
Also disables the python tests for the old python exporter.

So far linked proxies were just kept as-is, this is no longer an option.
Attempt to convert them into liboverrides as much as possible, though
some cases won't be supported:
- Appending proxies is broken since a long time, so conversion will fail
here as well.
- When linking data, some cases will fail to convert properly. in
particular, if the linked proxy object is not instanced in a scene
(e.g. when linking a collection containing a proxy as an
epty-instanced collection instead of a view-layer-instanced collection).
NOTE: converion when linking/appending is done unconditionnaly, option
to not convert on file load will be removed in next commit anyway.

Layer resync code would not yet fully properly deal with all possible

This fixes a similar issue as the previous commit, but this time the

Adds a second output to the edge angle node that shows the signed angle

This significantly reduces discontinuities on UV seams, by giving a better

Conceptually, this is the geometry that data is taken from,
not the target of an operation, so rename it from "Target"
to "Source". This was common user feedback and agreed
on in a recent sub-module meeting.
Today many users seem to think the output from
this node is a single curve with multiple splines.
This patch renames the geometry output socket
from "Curves" to "Curve Instances" to avoid confusion.

When weight painting the bone overlay is extremely intrusive,
effectively requiring either extensive use of hiding individual
bones, or disabling the whole bone overlay between selections.
This addresses the issue by adding a bone opacity slider that

This commit inserts a new menu item into the export menu called

For now the old Python exporter remains in the menu, along with

This completes 1a721c5dbe by versioning old files to correct the
region type. The "tools" region type is relatively standard for this type
of region and doesn't require any changes to the theme, unlike
the "nav bar" type, which would have been a reasonable choice.
This implements the design detailed in T92696 to support virtual
filenames for UDIM textures. Currently, the following 2 substitution
tokens are supported:
| Token | Meaning |
| ----- | ---- |
| <UDIM> | 1001 + u-tile + v-tile * 10 |
| <UVTILE> | Equivalent to u<u-tile + 1>_v<v-tile + 1> |
Example for u-tile of 3 and v-tile of 1:
filename.<UDIM>_ver0023.png --> filename.1014_ver0023.png
filename.<UVTILE>_ver0023.png --> filename.u4_v2_ver0023.png
For image loading, the existing workflow is unchanged. A user can select
one or more image files, belonging to one or more UDIM tile sets, and
have Blender load them all as it does today. Now the <UVTILE> format is
"guessed" just as the <UDIM> format was guessed before.
If guessing fails, the user can simply go into the Image Editor and type
the proper substitution in the filename. Once typing is complete,
Blender will reload the files and correctly fill the tiles. This
workflow is new as attempting to fix the guessing in current versions
did not really work, and the user was often stuck with a confusing
situation.
For image saving, the existing workflow is changed slightly. Currently,
when saving, a user has to be sure to type the filename of the first
tile (e.g. filename.1001.png) to save the entire UDIM set. The number
could differ if they start at a different tile etc. This is confusing.
Now, the user should type a filename containing the appropriate
substitution token. By default Blender will fill in a default name using
the <UDIM> token but the user is free to save out images using <UVTILE>
if they wish.

These pointers point to the new nodes when duplicating,
and their even used to point to "original" nodes for
"localized" trees. They're just a bad design decision
that make code confusing and buggy.
Instead, node copy functions now optionally add to a map
of old to new socket pointers. The case where the compositor
abused these pointers as "original" pointers are handled
by looking up the string node names.

Goals of this refactor:
* More unified approach to updating everything that needs to be updated
after a change in a node tree.
* The updates should happen in the correct order and quadratic or worse
algorithms should be avoided.
* Improve detection of changes to the output to avoid tagging the depsgraph
when it's not necessary.
* Move towards a more declarative style of defining nodes by having a
more centralized update procedure.
The refactor consists of two main parts:
* Node tree tagging and update refactor.
* Generally, when changes are done to a node tree, it is tagged dirty
until a global update function is called that updates everything in
the correct order.
* The tagging is more fine-grained compared to before, to allow for more
precise depsgraph update tagging.
* Depsgraph changes.
* The shading specific depsgraph node for node trees as been removed.
* Instead, there is a new `NTREE_OUTPUT` depsgrap node, which is only
tagged when the output of the node tree changed (e.g. the Group Output
or Material Output node).
* The copy-on-write relation from node trees to the data block they are
embedded in is now non-flushing. This avoids e.g. triggering a material
update after the shader node tree changed in unrelated ways. Instead
the material has a flushing relation to the new `NTREE_OUTPUT` node now.
* The depsgraph no longer reports data block changes through to cycles
through `Depsgraph.updates` when only the node tree changed in ways
that do not affect the output.
Avoiding unnecessary updates seems to work well for geometry nodes and cycles.
The situation is a bit worse when there are drivers on the node tree, but that
could potentially be improved separately in the future.
Avoiding updates in eevee and the compositor is more tricky, but also less urgent.
* Eevee updates are triggered by calling `DRW_notify_view_update` in
`ED_render_view3d_update` indirectly from `DEG_editors_update`.
* Compositor updates are triggered by `ED_node_composite_job` in `node_area_refresh`.
This is triggered by calling `ED_area_tag_refresh` in `node_area_listener`.
Removing updates always has the risk of breaking some dependency that no
one was aware of. It's not unlikely that this will happen here as well. Adding
back missing updates should be quite a bit easier than getting rid of
unnecessary updates though.

Initialise the BKE callback system in
`BlendfileLoadingBaseTest::SetUpTestCase()`. This allows certain tests
to run in debug mode (when `BLI_assert` is enabled).
The RNA setter now ensures that driver variables are uniquely named
(within the scope of the driver).
Versioning code has been added to ensure this uniqueness. The last
variable with the non-unique name retains the original name; this
ensures that the driver will still evaluate to the same value as before
this fix.
This also introduces a new blenlib function `BLI_listbase_from_link()`,
which can be used to find the entire list from any item within the list.

The versioning code was accidentally put not at the very bottom.
That lead to a situation where it wasn't run on some files that happened
to be within a specific short time frame.
Since the versioning code is idempotent, it can just run again on existing
files. Therefore, this commit just moves it back to the bottom so that it
is executed on all files again.
Broken Commit: rB5b61737a8f41688699fd1d711a25b7cea86d1530.
Saving with only a filename (from Python) wasn't being prevented,
while it would successfully write the file to the working-directory,
path remapping and setting relative paths wouldn't work afterwards
as `Main.filepath` would have no directory component.
Disallow this since it's a corner case which only ever occurs
when path names without any directories are used from Python,
the overhead of expanding the working-directory for all data saving
operations isn't worthwhile.
The following changes have been made:
- bpy.ops.wm.save_mainfile() without a filepath argument
fails & reports and error when the file hasn't been saved.
Previously it would write to "untitled.blend" and set the
`G.main->filepath` to this as well.
- bpy.ops.wm.save_mainfile(filepath="untitled.blend")
fails & reports and error as the filename has no directory component.
- `BLI_path_is_abs_from_cwd` was added to check if the path would
attempt to expand to the CWD.
Revert part of the fix from 073669dd85
that initialized the file-path on first save as it's no longer needed.
Also remove relbase argument to BLI_path_normalize as the destination
file paths shouldn't use relative locations.
In almost all cases there is no difference between `G.relbase_valid`
and checking `G.main->filepath` isn't an empty string.
In many places a non-empty string is already being used instead of
`G.relbase_valid`.
The only situation where this was needed was when saving from
`wm_file_write` where they temporarily became out of sync.
This has been replaced by adding a new member to `BlendFileWriteParams`
to account for saving an unsaved file for the first time.
