Sort of a followup to d177388979
Resolves the limitation mentioned there "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."
Part of #136895
Does not fully fix the report though, seems like deleting/relinking the
brush in `asset_reload` still need to do additional stuff to properly
revert the brush textures.

Since nodes are not uniquely assigned to zones (some nodes are in two
zones at the same time), it's better not to expose this detail in multiple
APIs. This avoids having to explain the behavior multiple times.
Now one just has to use `get_zone_by_node/socket` and can then use
a seperate method to get the zone stack for that zone like before.
This patch turns the options of the Tone Map node into inputs.
In the process, a few changes were made. Input ranges were adjusted to
remove artificial limits. The papers indeed mention those limits, but
they were only mentioned as typical values, not valid ranges.
- The Key option is no longer limited to 1.
- Gamma is no longer limited to a value of 3.
- Intensity is no longer limited to [-8, 8].
- Contrast is no longer limited to [0, 1].
A few renames were done to clarify options and match the reference
papers.
- Offset was renamed to Balance, since it is not really an offset, but
balances between shadows and highlights. This can be looked up in the
paper.
- Correction was renamed to Chromatic Adaptation, since it doesn't
really correct anything.
- Adaptation was renamed to Light Adaptation to distinguish from
Chromatic Adaptation and now default to global tone mapping, since
this is more useful by default.

Adds a C++ based FBX importer, using 3rd party ufbx library (design task:
#131304). The old Python based importer is still there; the new one is marked
as "(experimental)" in the menu item. Drag-and-drop uses the old Python
importer; the new one is only in the menu item.
The new importer is generally 2x-5x faster than the old one, and often uses
less memory too. There's potential to make it several times faster still.
- ASCII FBX files are supported now
- Binary FBX files older than 7.1 (SDK 2012) version are supported now
- Better handling of "geometric transform" (common in 3dsmax), manifesting
as wrong rotation for some objects when in a hierarchy (e.g. #131172)
- Some FBX files that the old importer was failing to read are supported now
(e.g. cases 47344, 134983)
- Materials import more shader parameters (IOR, diffuse roughness,
anisotropy, subsurface, transmission, coat, sheen, thin film) and shader
models (e.g. OpenPBR or glTF2 materials from 3dsmax imports much better)
- Importer now creates layered/slotted animation actions. Each "take" inside
FBX file creates one action, and animated object within it gets a slot.
- Materials that use the same texture several times no longer create
duplicate images; the same image is used
- Material diffuse color animations were imported, but they only animated
the viewport color. Now they also animate the nodetree base color too.
- "Ignore Leaf Bones" option no longer ignores leaf bones that are actually
skinned to some parts of the mesh.
- Previous importer was creating orphan invisible Camera data objects for
some files (mostly from MotionBuilder?), new one properly creates these
cameras.
Import settings that existed in Python importer, but are NOT DONE in the new
one (mostly because not sure if they are useful, and no one asked for them
from feedback yet):
- Manual Orientation & Forward/Up Axis: not sure if actually useful. FBX
file itself specifies the axes fairly clearly. USD/glTF/Alembic also do
not have settings to override them.
- Use Pre/Post Rotation (defaults on): feels like it should just always be
on. ufbx handles that internally.
- Apply Transform (defaults off, warning icon): not sure if needed at all.
- Decal Offset: Cycles specific. None of other importers have it.
- Automatic Bone Orientation (defaults off): feels like current behavior
(either on or off) often produces "nonsensical bones" where bone direction
does not go towards the children with either setting. There are discussions
within I/O and Animation modules about different ways of bone
visualizations and/or different bone length axes, that would solve this
in general.
- Force Connect Children (defaults off): not sure when that would be useful.
On several animated armatures I tried, it turns armature animation
into garbage.
- Primary/Secondary Bone Axis: again not sure when would be useful.
Importer UI screenshots, performance benchmark details and TODOs for later
work are in the PR.

If `f_new` is a double of an existing face and the existing face is
being reused, then the existing face already has custom-data and
multi-res data and etc.
There's also a good case to be made that custom or multireas data on the
existing face might be that way because it was hand-edited by the user,
and therefore it's superior to anything we'd interpolate or copy from
faces being removed.
Change BM_faces_join() to not waste time doing that.

This error is technically correct when the operators path doesn't
support relative paths.
The collection exporter allows relative paths and expands them before
passing the value to the operator.
Resolve by suppressing the warning.
Ref: !137510
Clearing a mesh's geometry without freeing the mesh has the requirement
that the mesh remain initialized afterwards. Freeing the mesh doesn't
have that requirement and corresponds to a destructor rather than move
construction with the default value. Avoiding conflating the two
operations simplifies some future feature additions (including #122398).
This was caused by the shadow map Z range loosing too much
precision on the large object.
This can be replicated by adding a very large object in the scene.
The normaly un-shadowed objects gets shadowed because the
float precision is not enough to represent their depth correctly.
To fix this, we bias the shadow depth by 2 ULP to make sure that
there is no self shadowing.
This bias has already been there, but was somehow removed because
of other fixes that simingly fixed this issue. But they did not.

The Clay Strips brush calculates a brush plane and local matrix to use
for a cube distance test. This test is done based on the sampled plane
center, not the current cursor position.
To make the node mask match this brush area, this commit reworks the
node mask calculation similar to the Plane brush, also calculating the
plane normal and plane center to be used later.
Finally, the relative radius scale of the brush is fixed to be a
constant SQRT(3) to ensure that the cube influence area is fully
circumscribed by the spherical distance query.
Further work here can change the type of BVH distance query done to
reduce the number of nodes processed by the brush.

We have an icon type called ICON_TYPE_VECTOR that are dynamically drawn
at runtime. These are created in icon_draw_size, which takes float
positions, but their callbacks all use integers instead. Truncating so
early in the process takes away flexibility to draw these at more ideal
sizes or to center them better. The complaint is a situation where we
mix ICON_TYPE_VECTOR for the colored collections and ICON_TYPE_SVG_MONO
for the white ones. Even though they both ultimately just draw the same
SVG icon the former way truncates position and size so there are times
they won't exactly line up.

Making local an intermediate collection in a liboverride hierarchy e.g.
will likely break the link between the objects in that collection, and
their hierarchy root ID (typically the top overridden collection).
This is fixed by this commit, by:
* Adding a new util, `lib_override_root_is_valid`, that check whether a
given liboverride ID is still 'connected' to its hierarchy root.
* Using this test in `BKE_lib_override_library_main_hierarchy_root_ensure`
to strengthen the detection of invalid root hierarchy pointers.

This commit applies the same calculation used when tilting the normal to
the inactive cursor display inside sculpt mode, as a way to indicate to
users how the normal is affected by the current tilt settings and pen
orientation.
Pull Request: https://projects.blender.org/blender/blender/pulls/137250
Pen tilt values come into Blender through ghost platforms and device
drivers with inconsistent and ambiguous directions. This PR codifies
that we consider tilt-x positive values to be rightward, negative
values as leftward. Similarly tilt-y positive is away from the user,
negative is toward the user. Comments are updated to make this clear.
This fixes Windows Ink (currently always returning left and away). This
also reverses the Wayland tily-y values to match. We might still have
to consider a user preference to swap directions if we find differences
within a platform.

In the past couple months, the basic operations needed for a new object
type were implemented, as well as basic edit mode tools. With that, the
object type is in a good enough state that it doesn't need to be hidden
behind an experimental option. That also resolves some inconsistency,
because the object type is already created by geometry nodes and used by
importers; it's weird that you can't add it manually as original data.
This also removes the "bounds" drawing flag for the object created from
the add menu. It's unnecessary now and there was even a TODO comment.

Masks for scrollbars were properly shrunk to match their drawn
representation in #135021, however, click logic was not updated
alongside this change.
For one, `mouse_in_scroller_handle` incorrectly assumed that if the
slider filled up the entire scrollbar extents, we would only be able to
select the bar. This code never ran in practice since `scrollers` were
always smaller than their mask, but now that they're the right size,
it's being run. Fix by removing the case.
It is also guaranteed that the "scroller"/"bubble"/"thumb" is not out of
view of the scrollbar track itself because it is clamped at the end of
`view2d_scrollers_calc` (which always runs before
`mouse_in_scroller_handle`), so this is dead code that can be removed.
Finally, rename `mouse_in_scroller_handle` to `scrollbar_zone_get` to
better represent its function.

This adds initial support for showing logged data in closures. This is more
tricky than the other zone types, because the zone content is evaluated
elsewhere. The main new thing here is a function that attempts to find where a
given closure is evaluated statically.
Finding this place statically is also important because we generally decide
which compute contexts we want to log before evaluation starts. That's because
we don't want to log everything (which is expensive), but just the places that
the user is currently looking at.
This also changed a bunch of CMakeLists.txt files so that these modules can
include NOD_* stuff, which is generally fine everywhere in editors code.

This patch replaces our own FindTBB module with TBB's own TBBConfig
module. On the technical side of things, this harvests the TBB CMake
config modules, and switches our TBB CMake find_package calls from
Module mode to Config mode. Integration was done using OpenPGL as a
blueprint for parsing TBB target's property back into CMake variables
(TBB_LIBRARIES and TBB_INCLUDE_DIRS).

Not sure why it was not done before... But it should be fine to
completely ignore the loopback relationships (mainly liboverride
hierarchy root pointers themselves, and owners of embedded and
shape key IDs) when handling hierarchies.
Quick tests on complex production cases here also showed no obvious
issue (or even change at all) with this tweak, so think it's safe to try
it out in main.
This make the shadow rays always multiply the lighting,
which can make renders with large light sources darker.
This bias introduced too many light leaking issues. And
these issues are made more visible since the introduction
of 410282e156.
Its first use was to avoid self shadowing artifacts from
large light sources. Since the shading was already
integrated over the visible hemisphere, it made sense
that the shadowing was also in the visible hemisphere.
However this only works if the shading is actually
clipped to the visible hemisphere above the geometric
normal, which might not always be the case.
Given it is better to have self shadowing noise than
light leaking, it is better to just removing this trick.
Self shadow noise can be mitigated by increasing the
sample count or by increasing the terminator bias.
Light leaking, on the other hand, has no known workaround.

The "Make Panel Toggle" operator does not check if active item is an input socket,
leading to a situation where it can be called on Boolean output sockets.
Doing this creates weird behavior where the panel and associated
operators believe it has a toggle, but is not reflected in the UI drawing.
Other weird behaviors include being able to rearrange output sockets
and apply the operator again to another output socket.
This patch adds a check in the operator's poll function to prevent it
from being called on output sockets.

This adds a simple `compute_context_for_edittree` function that returns the
"active" compute context for the given node editor. This is used in various
places, but previously one had to construct the compute context in multiple
steps (first find the root context (modifier/operator), then handle the tree
path). Since the edittree already has a specific active context, there should be
an easy way to retrieve that.
This also adds a few extra check that avoid redundant work that was done before.

Seems that this was a fundamental design problem that was resolved
with 3b6ee8cee7.
Since the vertex group names are stored on the mesh now, we can
just store their state in the undo mesh, and restore it when decoding
an undo step.

Creating f-curves one by one is quadratic complexity due to:
1) scanning all existing f-curves for possible name+index duplicates,
2) channelbag invariants recalculation after each f-curve addition.
3) f-curve array storage is reallocated for each f-curve addition.
In cases when many f-curves are created at once (primary case:
importing an animated character), using the newly added
fcurve_create_many is much faster, because it:
1) uses a hashtable for duplicate name+index checking, instead of
linear scan, and
2) recalculates channelbag invariants just once.
3) does f-curve array reallocation just once.
Importing USD file exported out of Blender Studio "Rain Restaurant"
scene (about 20k f-curves), on Ryzen 5950X goes 2.0 sec -> 0.9 sec.
