Subject: obj: vertex colors support in importer and exporter

Adds support for vertex colors to OBJ I/O.

Importer:

- Supports both "xyzrgb" and "MRGB" vertex color formats.
- Whenever vertex color is present in the file for a model, it is
  imported and a Color attribute is created (per-vertex, full float
  color data type). Color coming from the file is assumed to be sRGB,
  and is converted to linear upon import.

Exporter:

- Option to export the vertex colors. Defaults to "off", since not
  all 3rd party software supports vertex colors.
- When the option is "on", if a mesh has a color attribute layer,
  the active one is exported in "xyzrgb" form. If the mesh has
  per-face-corner colors, they are averaged on the vertices.
  Colors are converted from linear to sRGB upon export.

Subject: Fix T98782: ignore OBJ face normal indices if no normals are present

Some OBJ files out there (see T98782) have face definitions that
contain vertex normal indices, but the files themselves don't
contain any vertex normals. The code was doing a "hey, that's an
invalid index" and skipping these faces. But the old python importer
was silently ignoring these normal indices, so do the same here.

Subject: Fix T98715: Crash drag-dropping collection from outliner to ID
 property

The value of disabled buttons shouldn't be changed through dropping onto
it. Check for the disabled state in the drop operator poll, so the
dragging code will change the cursor to show that dropping isn't
possible at the given cursor location.

Subject: Fix T85729: Crash when exporting for USD and Alembic

Ensure the "null" node graph, which is the root node of the export
graph, always exists.

The crash occured when "Use Settings For" was set to Render, "Visible
Objects Only" was ticked, and a single parent object is in the scene but
disabled for render.

Because the only object attached to the root of the project was disabled
for export, there was no "null" root node added to the export graph.
This change will always add an empty "null" node with no children to the
graph at the start. Other objects will get added to its children as
required.

Subject: Render report: better wording for reference image updating

The old text was suggesting to run `BLENDER_TEST_UPDATE=1 ctest` for
failed tests. Now it's more clear that this is for the regeneration of
reference (ground truth) images, and that it will not touch passing test
cases.

It now also mentions to commit the new reference images to SVN, driving
the point home that this is for updating those, and not for making
failing tests succeed in general.

Subject: Fix T98813: crash with GPU subdiv in edit mode and instanced geometry

Instancing with geometry nodes uses just the evaluated Mesh, and ignores the
Object that it came from. That meant that it would try to look up the subsurf
modifier on the instancer object which does not have the subsurf modifier.

Instead of storing a session UUID and looking up the modifier data, store a
point to the subsurf modifier runtime data. Unlike the modifier data, this
runtime data is preserved across depsgraph CoW. It must be for the subdiv
descriptor contained in it to stay valid along with the draw cache.

As a bonus, this moves various Mesh_Runtime variables into the subsurf runtime
data, reducing memory usage for meshes not using subdivision surfaces.

Also fixes T98693, issues with subdivision level >= 8 due to integer overflow.

Subject: Fix: Don't allow duplicate color attribute operator in edit mode

The internal function relies on `CustomData_copy_data_layer` currently,
which doesn't work for BMesh. Support could be added as a special case
for BMesh, but in the meantime avoid bugs by just changing the poll.

Subject: Fix T98753: Outliner Unlink material in Blender File mode crashes

This issue was only exposed by ba49345705a3. The ID pointer of the
material's parent tree-element wasn't actually pointing to an ID, but to
the list-base containing the IDs. It was just unlikely to cause issues
in practice, although an assert was thrown.

Just don't do anything if the object or object-data to unlink the
material from could not be found. The following commit will introduce a
error message about this.

Subject: Outliner: Sanitize material unlinking callback, report errors

The callback would just assume that it's only called on materials, which
may in fact not be the case. It could also be called for other ID types
and layer collections (see `outliner_do_libdata_operation()`). Properly
check this now.

Also avoid faling silently when the object or object-data to unlink from
couldn't be determined. Report this to the user. Operators that just do
nothing are confusing.

Subject: Fix T98700: Regression: Crash when recursively nesting NLA meta
 strips

The `update_active_strip_from_listbase()` function took meta-strips in
the "source" list into account, but didn't recurse into the
corresponding meta-strip of the "destination" list. This is now fixed.

`update_active_strip_from_listbase()` needed a few changes to resolve
the issue:
- It was renamed to `find_active_strip_from_listbase()` to limit its
  reponsibility to just finding the active strip. It now leaves the
  assignment to the caller. This reduces the number of parameters by 1
  and makes recursion simpler.
- The destination strips are now, like the source strips, passed as
  `ListBase`, so that both source & dest can be recursed simultaneously.

Subject: Attributes: Adjustments to duplicate attribute API function

Use a name argument, for the same reasons as 6eea5f70e3b79e3c668.
Also reuse the layer and unique name creation in `BKE_id_attribute_new`
instead of reimplementing it. Also include a few miscellaneous cleanups
like using const variables and `std::string`.

Subject: Attributes: Add null check in color attribute duplicate operator

It's potentially possible that the attribute duplication could fail,
for whetever reason. There is no great reason not to be safe in
this high-level code.

Subject: Fix T98879: PBVH active attrs only optimization is buggy

PBVH draw has an optimization where it only sends the
active attribute to the GPU in workbench mode.  This
fails if multiple viewports are open with a mix of
workbench and EEVEE mode; it also causes severe lag
if any workbench viewport is in material mode.

There are two solutions: either add the code in sculpt-dev
that checks for EEVEE viewports at the beginning of each frame,
or integrate pbvh draw properly inside the draw manager
and let it handle which attributes should go to the GPU.

Subject: Fix T72831: Incorrect animation handling when strips overlap

Function `SEQ_transform_seqbase_shuffle_time` did not have access to
strip effects, and therefore could not handle their animation. Since
now transformation knows what strips can't be directly moved, but their
position depends on other strips, this collection of strips is passed as
argument, so animation can be offset correctly.

Subject: Cleanup: Move function definition to correct file

Function `SEQ_transform_handle_overlap` was declared in sequencer module
header file, but it was defined in editor/transform module.

Move definition to sequencer module.

Subject: GHOST/Wayland: fractional scaling support

GHOST_GetDPIHint now returns a value that takes fractional scaling into
account. Otherwise the integer scale is used since Wayland's API's use
integer scale values exclusively.

Use the same method as SDL to calculate the fractional scale.

Subject: Fix T98708: Crash on startup - OpenGL4.2 without conservative depth.

Intel iGPU (HD4000) supports OpenGL 4.4 but doesn't support conservative
depth. (GL_ARB_conservative_depth). This change will only check for the
availability of the extension.

Subject: Cleanup: various minor changes to wayland internal conventions

- Initialize values in the struct declarations
  (help avoid accidental uninitialized struct members).
- Use `wl_` prefix for some types to avoid e.g. `output->output`.
- Use `_fn` suffix for locally defined function variables.
- Use `_handle_` as separator for handlers, making function names easier
  to follow as this separates the handler name from the interface.
- Add doxy sections for listeners in GHOST_WaylandWindow.cpp.

Subject: Cleanup: avoid static_cast when accessing wayland windows

Rename get_window to window_from_surface and return a
GHOST_WindowWayland instead of an GHOST_IWindow since most callers
needed to cast. It also makes sense that an call for accessing windows
would return the native type.

Subject: Fix T98765: Regression: Unable to select mask points in clip editor

Re-organize de-selection so that there is less conflict between tracking
and masking operators.

Still not fully ideal: the LMB selection does not de-select everything
now since the `mask.select` with `deselect_all` is only added to the
keymap when the RMB is the select mouse. While this is sub-optimal, this
seems to be how mask selection behaved in the Image Editor in 3.1.

Not sure it worth looking into a more complete fix, as it will likely be
too big to be safe for a corrective release.
