Original rework of caches during undo/redo (see D8183) had a very bad
flaw hidden in it: using the key of a ghash as source of data.
While this was effectively working then (cache pointer itself being part
of the key, and said cache pointers not being cleared on file write),
this is a general very bad way to do things.
Now that cache pointers are more and more cleared on file write (as part
of clearing runtime-data to reduce false-positives when checking if an
ID has changed or not), this has to be fixed properly by:
* Not storing the cache pointer itself in the IDCacheKey.
* In undo context, in readfile code trying to preserve caches, store the
cache pointers as values of the mapping, together with the usages counter
The first change potentially affects all usages of
`BKE_idtype_id_foreach_cache`, but in practice this code is only used by
memfile reading code (i.e. undo) currently.

Python exceptions are now shown in the info editor,
this also resolves an old bug where errors were printed twice.
This was originally based on D9752 by @ShadowChaser although many
changes have been made from the original patch.
Details:
- BPy_errors_to_report no longer prints additional output.
- BKE_report_print_test was added so it's possible to check if calling
BKE_report also printed to the stdout.
- Callers to BPy_errors_to_report are responsible for ensuring output
is printed to the stdout/stderr.
- Python exceptions no longer add a trailing newline,
needed to avoid blank-space when displayed in the info-editor.

Ideally this wouldn't be needed, I couldn't find a good solution
to avoid casting when comparing const/non-const pointers in this case.

This is an internal usage parameter.
No functional changes.
|

The parameters indicating whether it is allocated are always `false` and
it is up to the caller to free them.
Also clang-format was triggered.

The `BVHCacheType bvh_cache_type` parameter defines specific
`BVHTrees` that cannot be customized.
So it doesn't make sense to pass this value to any
`*bvhtree_from_[...]_ex` function as the `BVHTrees` created in these
cases are custom and cannot be saved in the cache.
This also resulted in a nice cleanup in the code.

In summary the changes are:
- Merge all `bvhtree_from_mesh_*.*_setup_data` in a single utility
- Create `bvhtree_from_editmesh_setup_data`
- Setup data only once in `BKE_bvhtree_from_mesh_get` and `BKE_bvhtree_from_editmesh_get`
Also the behavior of `BKE_bvhtree_from_mesh_get` and
`BKE_bvhtree_from_editmesh_get` changed a bit:
- If a null tree is cached, don't set the `data` to zero. This tree is not an error and the others data can still be used.
- If a null tree is returned, don't set the `data` to zero. Matches the previous change.

color attribute system.
This commit removes sculpt colors from experimental
status and unifies it with vertex colors. It
introduces the concept of "color attributes", which
are any attributes that represents colors. Color
attributes can be represented with byte or floating-point
numbers and can be stored in either vertices or
face corners.
Color attributes share a common namespace
(so you can no longer have a floating-point
sculpt color attribute and a byte vertex color
attribute with the same name).
Note: this commit does not include vertex paint mode,
which is a separate patch, see:

This adds missing cases to detect edit mode for Curves objects.
Unlike other object types, Curves do not have specific edit data,
rather we edit the original data directly, and rely on `Object.mode`.
For this, `BKE_object_data_is_in_editmode` had to be modified to
take a pointer to the object. This affects two places: the outliner
and the dependency graph. For the former place, the object pointer
is readily available, and we can use it. For the latter, the object
pointer is not available, however since it is used to update edit
mode pointers, and since Curves do not have such data, we can
safely pass null to the function here.
This also fixes the assertion failure that happens when closing a file
in edit mode.

Instead of using `CurveEval` to draw the curve wire edges, use
the new `Curves` data-block, which is already built as part of
an object's evaluated geometry set whenever there is a
`CurveComponent`.
This means that we can remove `Curve`'s temporary ownership
of `CurveEval` for drawing (added in 9ec12c26f16ea3da1e),
which caused a memory leak as described in T96498.
In my testing this improved performance by around 1.5x during
viewport playback, back to the performance of 3.1 before the
curve data structure transition started.
The next step of using the GPU to do the final curve evaluation
for the viewport is described in T96455, but is unrelated.

This commit furthers some of the changes that were started in
rBb9febb54a492 and subsequent commits by changing the way surface
objects are presented to render engines and other users of evaluated
objects in the same way. Instead of presenting evaluated surface objects
as an `OB_SURF` object with an evaluated mesh, `OB_SURF` objects
can now have an evaluated geometry set, which uses the same system
as other object types to deal with multi-type evaluated data.
This clarification makes it more obvious that lots of code that dealt
with the `DispList` type isn't used. It wasn't before either, now it's
just *by design*. Over 1100 lines can be removed. The legacy curve
draw cache code is much simpler now too. The idea behind the further
removal of `DispList` is that it's better to focus optimization efforts
on a single mesh data structure.
One expected functional change is that the evaluated mesh from surface
objects can now be used in geometry nodes with the object info node.
Cycles and the OBJ IO tests had to be tweaked to avoid using evaluated
surface objects instead of the newly exposed mesh objects.

This adds a new Grow/Shrink brush which is similar to the Length
brush in the old hair system.
* It's possible to switch between growing and shrinking by hold
down ctrl and/or by changing the direction enum.
* 3d brush is supported.
* Different brush falloffs are supported.
* Supports scaling curves uniformly or shrinking/extrapolating
them. Extrapolation is linear only in this patch.
* A minimum length settings helps to avoid creating zero-sized curves.

Those geometry types are expected to behave the same as e.g. mesh
with respect to data copying. The fact that this was not enabled
already was an oversight in the initial commit that added these types.

This patch adds channel region to VSE timeline area for drawing channel
headers. It is synchronizedwith timeline region. 3 basic features are
implemented - channel visibility, locking and name.
Channel data is stored in `SeqTimelineChannel` which can be top-level
owned by `Editing`, or it is owned by meta strip to support nesting.
Strip properties are completely independent and channel properties are
applied on top of particular strip property, thus overriding it.
Implementation is separate from channel regions in other editors. This
is mainly because style and topology is quite different in VSE. But
also code seems to be much more readable this way.
Currently channels use functions similar to VSE timeline to draw
background to provide illusion of transparency, but only for background
and sfra/efra regions.
Great portion of this patch is change from using strip visibility and
lock status to include channel state - this is facilitated by functions
`SEQ_transform_is_locked` and `SEQ_render_is_muted`
Originally this included changes in D14263, but patch was split for
easier review.

Light groups are a type of pass that only contains lighting from a subset of light sources.
They are created in the View layer, and light sources (lamps, objects with emissive materials
and/or the environment) can be assigned to a group.
Currently, each light group ends up generating its own version of the Combined pass.
In the future, additional types of passes (e.g. shadowcatcher) might be getting their own
per-lightgroup versions.
The lightgroup creation and assignment is not Cycles-specific, so Eevee or external render
engines could make use of it in the future.
Note that Lightgroups are identified by their name - therefore, the name of the Lightgroup
in the View Layer and the name that's set in an object's settings must match for it to be
included.
Currently, changing a Lightgroup's name does not update objects - this is planned for the
future, along with other features such as denoising for light groups and viewing them in
preview renders.

The Alembic procedural was only enabled during viewport renders
originally because it did not have any caching strategy. Now that
is does, we can allow its usage in final renders.
This also removes the `dag_eval_mode` argument passing to
`ModifierTypeInfo.dependsOnTime` which was originally added to detect if
we are doing a viewport render for enabling the procedural.

This commit moves declarations that depend on `FN_field.hh` out of
`BKE_geometry_set.hh` into `BKE_geometry_fields.hh`. This helps to
reduce the number of areas that need to depend on the functions module,
which recently came in in review of D11591.
In the future we may have a library of standard field inputs in order to
make composing algorithms easier, so it makes sense to have a header
that could contain them and some basic related utilities relating the
concepts of geometry and fields.
Reducing use of unnecessary headers may also reduce compilation time.

This commit ports the "Set Handle Positions" and "Set Hanle Type"
nodes to use the new curves data-block. The nodes become simpler
and likely much faster too, though they're usually not the bottleneck
anyway.
Most of the code is ported from `BezierSpline` directly. The majority
of the complexity comes from the interaction between different
automatically calculated handle types. In comparison `BezierSpline`,
the calculation of auto handles is done eagerly-- mostly because it's
simpler. Eventually lazy calculation might be good to add.

Direct replacement of code:
- memcpy of a single point is done as a shallow_copy() assignment.
- memcpy of a range of points is done with an explicit cast to void*
to tell compiler that we really want to memcpy even a non-trivial
type.
In some cases it seems that memcpy can be used more (points are copied
in a loop). Those left as-is since this is supposed to be a simple
cleanup.

This commit makes the dot grid used as background in the node editor
more visually stable when zooming in and out.
The dot grid now uses a continuously subdividing pattern, where
each level of subdivision divides the previous five times, similar to
the line grid in the 3D viewport.
The maximum for the "Grid Levels" theme setting is changed to 3, since
any further subdivisions are too small to be visible.
The "Grid Levels" value for the default themes "Blender Dark" and
"Blender Light" is therefore changed to 3, as well.

When a `GPencilUpdateCacheNode` is created, it always allocates the
`children` pointer. This should not be freed until the whole cache is
deleted.
The `cache_node_update` would free the `children` pointer in a specific

This commit adds calculation of lengths along the curve for each
evaluated point. This is used for sampling, resampling, the "curve
parameter" node, and potentially more places in the future.
This commit also includes a utility for calculation of uniform samples
in blenlib. It can find evenlyspaced samples along a sequence of points
and use linear interpolation to move data from those points to the
samples. Making the utility more general aligns better with the more
functional approach of the new curves code and makes the behavior
available elsewhere.
A "color math" header is added to allow very basic interpolation
between two colors in the `blender::math` namespace.
