The goal is to give technical artists the ability to optimize modifier usage
and/or geometry node groups for performance. In the long term, it
would be useful if Blender could provide its own UI to display profiling
information to users. However, right now, there are too many open
design questions making it infeasible to tackle this in the short term.
This commit uses a simpler approach: Instead of adding new ui for
profiling data, it exposes the execution-time of modifiers in the Python
API. This allows technical artists to access the information and to build
their own UI to display the relevant information. In the long term this
will hopefully also help us to integrate a native ui for this in Blender
by observing how users use this information.
Note: The execution time of a modifier highly depends on what other
things the CPU is doing at the same time. For example, in many more
complex files, many objects and therefore modifiers are evaluated at
the same time by multiple threads which makes the measurement
much less reliable. For best results, make sure that only one object
is evaluated at a time (e.g. by changing it in isolation) and that no
other process on the system keeps the CPU busy.
As shown below, the execution time has to be accessed on the
evaluated object, not the original object.
```lang=python
import bpy
depsgraph = bpy.context.view_layer.depsgraph
ob = bpy.context.active_object
ob_eval = ob.evaluated_get(depsgraph)
modifier_eval = ob_eval.modifiers[0]
print(modifier_eval.execution_time, "s")

Move then the location of this setting to `TransInfo::modifiers`.
BGL deprecation calls used to be reported on each use. As bgl calls
are typically part of a handler that is triggered at refresh this
could lead to overflow of messages and slowing down systems when
the terminal/console had to be refreshed as well.
This patch only reports the first 100 bgl deprecation calls. This
gives enough feedback to the developer that changes needs to be made
. But still provides good responsiveness to users when they have
such add-on enabled. Only the first frames can have a slowdown.
This patch adds two new kernels: SORT_BUCKET_PASS and SORT_WRITE_PASS. These replace PREFIX_SUM and SORTED_PATHS_ARRAY on supported devices (currently implemented on Metal, but will be trivial to enable on the other backends). The new kernels exploit sort partitioning (see D15331) by sorting each partition separately using local atomics. This can give an overall render speedup of 2-3% depending on architecture. As before, we fall back to the original non-partitioned sorting when the shader count is "too high".

The merge down operator was sometimes copying the wrong frame, which altered the animation.
While merging the layers, it is sometimes needed to duplicate a keyframe,
when the lowest layer does not have a keyframe but the highest layer does.
Instead of duplicating the previous keyframe of the lowest layer, the code

This patch fixes the issue by setting the previous keyframe of the layer as its active frame before duplication.

This is both a cleanup and a preparation for the Principled v2 changes.
Notable changes:
- Clearcoat weight is now folded into the closure weight, there's no reason
to track this separately.
- There's a general-purpose helper for computing a Closure's albedo, which is
currently used by the denoising albedo and diffuse/gloss/transmission color
passes.
- The d/g/t color passes didn't account for closure albedo before, this means
that e.g. metallic shaders with Principled v2 now have their color texture
included in the glossy color pass. Also fixes T104041 (sheen albedo).
- Instead of precomputing and storing the albedo during shader setup, compute
it when needed. This is technically redundant since we still need to compute
it on shader setup to adjust the sample weight, but the operation is cheap
enough that freeing up the storage seems worth it.
- Future changes (Principled v2) are easier to integrate since the Fresnel
handling isn't all over the place anymore.
- Fresnel handling in the Multiscattering GGX code is still ugly, but since
removing that entirely is the next step, putting effort into cleaning it up

For some buttons the type is changed after construction, which means the button

slider buttons this way. New code was unintentionally overriding the button
type after reconstruction with the old type again.
Use the `SharedCache` concept introduced in D16204 to share lazily
calculated evaluated data between original and multiple evaluated
curves data-blocks. Combined with D14139, this should basically remove
most costs associated with copying large curves data-blocks (though
they add slightly higher constant overhead). The caches should
interact well with undo steps, limiting recalculations on undo/redo.
Options for avoiding the new overhead associated with the shared
caches are described in T104327 and can be addressed separately.
Simple situations affected by this change are using any of the following data
on an evaluated curves data-block without first invalidating it:
- Evaluated offsets (size of evaluated curves)
- Evaluated positions
- Evaluated tangents
- Evaluated normals
- Evaluated lengths (spline parameter node)
- Internal Bezier and NURBS caches
In a test with 4m points and 170k curves, using curve normals in a
procedural setup that didn't change positions procedurally gave 5x
faster playback speeds. Avoiding recalculating the offsets on every
update saved about 3 ms for every sculpt update for brushes that don't
change topology.

Rather than writing worse code, allow non-trivial construction for `uiBut`.
Member-initializing all members is annoying since there are so many, but rather
safe than sorry. As we use more C++ types (e.g. convert callbacks to use
`std::function`), this should become less since they initialize properly on
default construction.
Also use proper C++ inheritance for `uiBut` subtypes, the old way to allocate

Currently this conversion (which happens when using modifiers in edit
mode, for example) is completely single threaded. It's harder than some
other areas to multithread because BMesh elements don't always know
their indices (and vise versa), and because the dynamic AoS format
used by BMesh makes some typical solutions not helpful.
This patch proposes to split the operation into two steps. The first
updates the indices of BMesh elements and builds tables for easy
iteration later. It also checks if some optional mesh attributes
should be added. The second uses parallel loops over all elements,
copying attribute values and building the Mesh topology.
Both steps process different domains in separate threads (though the
first has to combine faces and loops). Though this isn't proper data
parallelism, it's quite helpful because each domain doesn't affect the
others.
**Timings**
I tested this on a Ryzen 7950x with a 1 million face grid, with no
extra attributes and then with several color attributes and vertex
groups.
| File | Before | After |
| Simple | 101.6 ms | 59.6 ms |
| More Attributes | 149.2 ms | 65.6 ms |
The optimization scales better with more attributes on the BMesh. The
speedup isn't as linear as multithreading other operations, indicating
added overhead. I think this is worth it though, because the user is
usually actively interacting with a mesh in edit mode.

The recursion depth was checked for equality with a maximum depth,
allowing leaves with more primitives if a certain depth was reached.
However, a single leaf must always use the same material (including
set_smooth), so if a leaf contained multiple materials it was split
anyway. This meant that in the next recursion step the depth was
larger than the cutoff value and it would go back to recursing until
the number of primitives was small enough, ignoring the recursion
depth for the rest of the process.
In certain edge cases this could lead to a stack overflow.
Even with the check changed from 'equality' to 'larger or equal'
this could still fail in the pathological case where every primitive

When the "Hide Value" option of a group input is enabled, only its name

The image manager used to handle OSL textures on the GPU by
default loads images after displacement is evaluated. This is a
problem when the displacement shader uses any textures, hence
why the geometry manager already makes the image manager
load any images used in the displacement shader graph early

This only handled Cycles image nodes however, not OSL nodes, so
if any `texture` calls were made in OSL those would be missed and
therefore crash when accessed on the GPU. Unfortunately it is not
simple to determine which textures referenced by OSL are needed
for displacement, so the solution for now is to simply load all of
them early if true displacement is used.

into account whether the single attribute set is required or not.
Allow to explicitly swap node links by pressing the alt-key while
reconnecting node links. This replaces the old auto-swapping based on
matching prefixes in socket names.
The new behavior works as follows:
* By default plugging links into already occupied (single input)
sockets will connect the dragged link and remove the existing one.
* Pressing the alt-key while dragging an existing node link from one
socket to another socket that is already connected will swap the
links' destinations.
* Pressing the alt-key while dragging a new node link into an already
linked socket will try to reconnect the existing links into another
socket of the same type and remove the links, if no matching socket
is found on the node. This is similar to the old auto-swapping.
Swapping links from or to multi input sockets is not supported.

When group of strips is duplicated and driver references other strip,

pick the first prim) as well as matches the logic in Pixar's Maya USD

- Applies the MaterialBindingAPI to prims with material binding

Removing all OSL script nodes from the shader graph would cause that
graph to no longer report it using `KERNEL_FEATURE_SHADER_RAYTRACE`

itself still would have the `has_surface_raytrace` field set.
This caused kernels to be reloaded without shader raytracing support, but
later the `DEVICE_KERNEL_INTEGRATOR_SHADE_SURFACE_RAYTRACE`

Fix that by ensuring `has_surface_raytrace` is reset on every shader update,

BKE blendfile should not be allowed to deal with DNA deprectaed data, so

This is required since a valid value is always written in .blend files

When the sort weights are a single value, they have no effect,
so sorting the relevant indices for the element will be wasted work.
The sorting is expensive compared to the rest of the node. In my
simple test of the points of curve node, it became 6 times faster
when the weights are a single value.
On some occasions, as in cases where transform operations are triggered
via gizmos, the constrain orientations that can be toggled with
multiple clicks of X, Y or Z were repeated.
There is no use in maintaining repeated orientations.
Image Transform use linear or nearest sampling during editing and exporting.
This gets sampling is fine for images that aren't scaled. When sequencing
however you mostly want use some sort of scaling, that leads to poorer
quality.
This change will use sub-sampling to improve the quality. This is only
enabled when rendering. During editing the subsampling is disabled to
keep the user interface reacting as expected.
Another improvement is that image transform is stopped at the moment
it hadn't sampled at least 4 samples for a scan line. In that case we
expect that there are no further samples that would change to result.
In a future patch this could be replaced by a ray/bounding bo intersection
as that would remove some unneeded loops in both the single sampled and
sub sampled approach.
Add an `object.modifiers.move()` method, similar to the one
for constraints and some other collections. Currently reordering
modifiers requires using operators, which depend on context.
The implementation is straightforward, except for the need to
make the severity of errors reported by the underlying editor
code into a parameter, so that the new Python API function
reports any problems as Python exceptions, and refactoring
the code to allow aborting a blocked move before making any
changes. I also turn the negative index condition from an assert

Originally, function `sequencer_generic_invoke_xy_guess_channel`
looked in what channel the last strip of the same type is and the
channel used for new strip placement. This was changed as a workaround
when sound strips were added below movie strips
(58bea005c5).
Now these workarounds aren't necessary, but the function was left
unchanged.
Current logic is for adding movie strip to channel 1 is:
- Sound is added to channel 1
- Video is added to channel 2
- If there is only video, it is added to channel 1
Since movie may, or may not contain sound, it is not possible to align
added strips in a way that was done before, unless timeline is analyzed
more in detail, but this would be quite inefficient.
Also, note, that the code did not work, if strip is added next to
previous one, so it mostly did not work as intended.
This commit changes:
- Fix alignment not working when strip is added right next to previous
strip
- Assume that movie strips have sound strip underneath it, so channel
below last movie strip is picked
- For other strip types, pick channel of the last strip of same type
Ultimately, the code is still rather weak, and better system, like using
channel where strip was manually moved, or concept of "typed channels"
would improve this feature.
There is not much documentation on the "snap_point" property, but by
code it is possible to note that it serves to set a target snap point
and is of internal use as it is hidden from the Redo panel.
However, this property was still very dependent on Tools settings and
if set to an operator's call, it changes the scene configurations
inadequately.
Therefore,
- remove this dependency from UI for rotation and resize operators,
- do not change the state of the snap in the scene and
- cleanup the code.
Some transform modes are changeable, so callbacks should be reset
together.
Currently the unchanged `transform_matrix` callback is not a major
issue as it is only used for gizmos and gizmos stop updating when
changing the operator type.

In many cases when reading undo memfile, n the 'restore id from old
main' part of the process, the 'id_old' is not set, which means that

In practice this is likely not an issue (see comment in code for details),
but at least explicitely check for a nullptr `id_old` pointer.

Currently only affects 'UI' IDs (WindowManager, Screen, etc.), but in

Based on "Sampling the GGX Distribution of Visible Normals" by Eric Heitz
(https://jcgt.org/published/0007/04/01/).
Also, this removes the lambdaI computation from the Beckmann sampling code and
just recomputes it below. We already need to recompute for two other cases
(GGX and clearcoat), so this makes the code more consistent.
In terms of performance, I don't expect a notable impact since the earlier
computation also was non-trivial, and while it probably was slightly more
accurate, I'd argue that being consistent between evaluation and sampling is
more important than absolute numerical accuracy anyways.

Simon mentioned that this gets in the way more than it helps. No geometry
sockets currently show up in the modifier panel. People may build node groups
that have multiple geometry inputs that can be used when the group is used
as node instead of as modifier.
In the future we could also allow e.g. choosing an object to pass into a geometry
socket. That has the problem that we'd also have to duplicate other functionality
of the Object Info node (original vs. relative space).
There were two issues:
* The `new_point_counts_per_curve` was one too large, resulting in
`interpolate_from_neighbors` reading invalid memory.
* Writing the counts into the existing offsets array didn't quite work
because there can be a collision at the offset right between the
last old curve and the first new point. There was a race condition
where this value could be read and written at the same time.
When some path property was displayed in the File Browser, clicking the

Current implementation had some faulty assumtions and had some work

The main reason for this was that the implementation didn't add new

The new implementation will extract a solution and use this solution

Make the functions more flexible and more generic by changing the curves
arguments to the curve offsets. This way, theoretically they could become
normal utility functions in the future. Also do a consistency pass over
the algorithms that generate new curves geometry for naming and
code ordering, and use of utility functions. The functions are really
quite similar, and it's much easier to tell this way.
The most time-consuming operation in merge by distance is to find
duplicate faces (faces that are different but have the same vertices).
Therefore, some strategies were planned to optimize this algorithm:
- Store the corner indices in an array thus avoiding multiple calls of `weld_iter_loop_of_poly_next`;
- Create a map of polygons linked to edges instead of linked to vertices - this decreases the number of connections and reduces the calculation of the intersection of polygon indices.
There are other fields to optimize, like reusing the `wpolys` array
instead of creating a new array of corner offsets. And join some arrays
as members of the same struct to be used in the same buffer.
But for now, it is already a nice optimization. And the new
`poly_find_doubles` function can be reused in the future to create a
generic utility.
The result of the optimization varies greatly depending on the number
of polygons, the size of each polygon and the number of duplicates.
On average it was something around 2 times faster.

The code in questions comes from Shewchuk's triangle code, which
hasn't been updated to fix the out-of-buffer access problem
that ASAN finds in the delaunay unit test. The problem is benign:
the code would exit the loop before using the value fetched from
beyond the end of the buffer, but to make ASAN happy, I put in
a couple extra tests to not fetch values that aren't going to be used.
There's a compromise of a code parameter called BEVEL_GOOD_ANGLE,
and bugs T44961, T86768, T95335, and this one, are all about problems
with various values of that parameter. If an angle of an adjacent
non-beveled edge is too close to that of the beveled edge, then you
get spikes. The BEVEL_GOOD_ANGLE says that if you are within that
angle difference, then no bevel happens. If the value is too small
then one gets spikes for certain models people build; if the value
is too large, then other people are annoyed that no bevel happens.
Hopefully this compromise in this commit is the final one I will do
before switching to Bevel v2, where none of this should be an issue.
Regression in [0] caused mouse wheel events over windows without focus

This can improve performance in some circumstances when there are
vectorized and/or unrolled loops. I especially noticed that this helps
a lot while working on D16970 (got a 10-20% speedup there by avoiding
running into the non-vectorized fallback loop too often).
This isn't correct as window activation is handled separately
from the cursor entering/leaving a window.
This would call de-activate when the cursor moved outside the window
even though the window remained focused.
Rely on focus changes which already handle activate/deactivate events.

These commits moved flags from `eLineArtGPencilModifierFlags` to

This improves performance in cases where the Set Position node is "turned off"

It's possible that the node still takes some time in this case currently, because
it is destructing the input fields which may reference geometries that need
to be destructed as well. We could potentially change this node (and others)
so that the field inputs are only requested when the selection is not a

This adds a new `Interpolate Curves` node. It allows generating new curves
between a set of existing guide curves. This is essential for procedural hair.
Usage:
- One has to provide a set of guide curves and a set of root positions for
the generated curves. New curves are created starting from these root
positions. The N closest guide curves are used for the interpolation.
- An additional up vector can be provided for every guide curve and
root position. This is typically a surface normal or nothing. This allows
generating child curves that are properly oriented based on the
surface orientation.
- Sometimes a point should only be interpolated using a subset of the
guides. This can be achieved using the `Guide Group ID` and
`Point Group ID` inputs. The curve generated at a specific point will
only take the guides with the same id into account. This allows e.g.
for hair parting.
- The `Max Neighbors` input limits how many guide curves are taken
into account for every interpolated curve.

Fixes bug where other islands sometimes get their masks cleared (or
filled) in strange circumstances. Still need to figure out the
correct behavior for spherical falloff.
Mesh islands (shells) are now calculated on an as-needed
basis and cached inside of a temp attribute,
`sculpt_topology_island_key`. This attribute is updated
as needed when geometry changes (e.g. the trim brush)
or when mesh visibility changes.
This replaces the old behavior where the "topology" automasking
mode would walk the entire mesh on every stroke.
The background evaluation samples the sky discretely, so if the sun is
too small, it can be missed in the evaluation. To solve this, the sun is
ignored during the background evaluation and its contribution is
computed separately.
Add an RNA API function that gives an array of the normals for every control point.
The normals depend on the `normal_mode` attribute, which can currently be
minumum twist or Z-up, though more options are planned. Normals are currently
evaluated on the evaluated points and then sampled back to the control points.
Because that can be expensive, a normal mode that only does a first evaluation
on control points may be important
The function is intended to be used by Cycles, so it doesn't have to implement
the calculation of normals itself. They can be interpolated between control points
and normalized.
For best performance, the function should only be called once, since it does the
full calculation for every control point every time it is called.

Based on discussion about T102962, rename the "Face Set Boundaries" node
to "Face Group Boundaries" and the Accumulate Field node's "Group Index"
socket to "Group ID". This convention of "__ Group" and "Group ID" will
be used more in other nodes in the future.
This commit doesn't affect forwards or backwards compatibility.
The reverse iteration added in e091291b5b didn't handle
the case where there are no nodes properly. Thanks to Iliya Katueshenock
for investigating this.
While we do need higher level utilities for copying attributes
between geometries, this currently isn't used and it's not clear
that it will be the right abstraction in the end.
The default when there is no cyclic attribute is that none of the curves
are cyclic. In the mesh to curve node, avoid creating the attribute with
just false to save time and memory usage. Also avoid looking up the
attribute twice in the trim node.
When all the curves are poly curves, skip the work of building a
separate array of offsets for the evaluated points (which are the
same as the control points). This saves 1-4ms on every reevaluation
in test files with many curves.
Standardizing the process of creating a new CurvesGeometry with
different curve sizes based on an existing curves is helpful, since
there are a few methods to simplify the process that aren't obvious
at first, like filling the offsets with sizes directly and accumulating
them to become sizes.
Also, in the trim curves node, avoid creating the curve types attribute
all the time. Use the special API functions for the types which do
some optimizations automatically. Also use a more consistent
method to copy the curve domain data, and correct some comments.
The same logic from D17025 is used in other places in the curve code.
This patch uses the class for the evaluated point offsets and the Bezier
control point offsets. This helps to standardize the behavior and make
it easier to read.
Previously the Bezier control point offsets used a slightly different standard
where the first point was the first offset, just so they could have the same
size as the number of points. However two nodes used a helper function
to use the same `OffsetIndices` system, so switch to that there too.
That requires removing the subtraction by one to find the actual offset.
Also add const when accessing data arrays from curves, for consistency.

This patch adds re-calculation logic (new `BKE_nlastrip_recalculate_blend()` method) to the blend-in/out on transformations to clamp values, and avoid over/under shoot.
The `BKE_nlastrip_recalculate_blend()` encapsulates the existing logic for both the `rna_NlaStrip_blend_in_set()` and `rna_NlaStrip_blend_out_set()` methods into a single BKE method that we an execute as needed. The fact that blend-in is first decreased, is strictly on the order of calculation. My suspicion is that //if// the blend-in / blend-our values were working as intended, the RNA set methods would update in order, and we'd experience the same thing. In short, the choice here was to linearly combine the logic, without making any assumptions of my own.

In above commit, `DT_layer_items` shared both `DT_TYPE_MPROPCOL_LOOP` |
`DT_TYPE_MLOOPCOL_LOOP` in a single EnumPropertyItem value "Colors".
This is a bit unusual, but probably allowed.
As a consequence, checks for specific datatypes would fail when selecting
such EnumPropertyItem:
- `DT_DATATYPE_IS_MULTILAYERS` (uses `ELEM` to check distinct entries --
would return false)
- `BKE_object_data_transfer_dttype_to_srcdst_index` (would return
`DT_MULTILAYER_INDEX_INVALID`)
These places have now been corrected to take these "special" values into
account.
Another issue was that multiple EnumPropertyItems with the same value
could be created in dt_add_vcol_layers() if attributes of the same
domain, but different color types are in play (could lead to crashes)
and that has also been corrected.
Also: above commit did not give the choice of transfering color
attributes from the vertex domain (only face corner attributes could be
chosen), this has now been added. DT_layer_vert_items (used from the
modifier) already had this included so this was only an issue when using
the operator outside of the modifiers panel.
Since we now feature two domains, the single "VCOL" in the enum has been
split into "COLOR_VERTEX" and "COLOR_CORNER". This will break existing
scripts calling bpy.ops.object.datalayout_transfer and will be marked as
a breaking change in the release notes.

There is a utility method on `CurvesGeometry` to build a map of the
curve for each point. Use that in two more places and make sure its
implementation is multithreaded, which gives a slight speedup
in a simple test file.
When doing partial reloads of asset libraries (only reload assets from
the current file, e.g. after undo re-allocated ID pointers), we'd end up
with assets that don't have their asset data read correctly. It would
execute a branch that didn't set the asset library object necessary to
create and store asset representations.
Steps to reproduce were:
* Open .blend file with geometry node assets in there
* In a geometry node editor, press Shift+A to open the add menu
* Cancel
* Move a node
* Undo
* Press Shift+A again
This allows an engine to perform GPU side view specification and let the
draw manager extract the culling informations (bounds).
To this end, the matrices ubo gets exposed to be able to write to it.
`compute_procedural_bounds()` need to be explicitely called before any
main pass using the culling result.
This abstraction is rarely used. It could be replaced by some more
general "query" API in the future. For now it's easier to just compare
pointers in the Set Position node where this was used.
This is possible now, because mesh positions are stored as flat `float3`
arrays (previously, they were stored as `MVert` with some other data
interleaved).
This changes how we access the points that correspond to each curve in a `CurvesGeometry`.
Previously, `CurvesGeometry::points_for_curve(int curve_index) -> IndexRange`
was called for every curve in many loops. Now one has to call
`CurvesGeometry::points_by_curve() -> OffsetIndices` before the
loop and use the returned value inside the loop.
While this is a little bit more verbose in general, it has some benefits:
* Better standardization of how "offset indices" are used. The new data
structure can be used independent of curves.
* Allows for better data oriented design. Generally, we want to retrieve
all the arrays we need for a loop first and then do the processing.
Accessing the old `CurvesGeometry::points_for_curve(...)` did not follow
that design because it hid the underlying offset array.
* Makes it easier to pass the offsets to a function without having to
pass the entire `CurvesGeometry`.
* Can improve performance in theory due to one less memory access
because `this` does not have to be dereferenced every time.
This likely doesn't have a noticable impact in practice.

Since a year and a half ago we've been switching to a new way to

All builtin nodes with a static set of sockets have switched, but one

Under some circumstances (loading autosaves), we end up reading from
files that were saved with the new mesh format (after T95965). When
that happens we should skip the conversion from the old format to
avoid data-loss. This will also give forward compatibility when we
stop saving in the old format completely in 4.0.
Here I mostly just check if the attributes in the new format already
exist. Along with checking for the null status of `Mesh::mvert`, that
should cover the majority of cases.

As noted in comments, there are a lot of false positives which can't
be conveniently suppressed. Many of these warnings were caused by
`float x, y, z` being passed as `float[3]` using a pointer to `x`.
This makes `GVArrayImpl` and `VArrayImpl` more similar.
Only passing the pointer instead of the span also increases
efficiency a little bit. The downside is that a few asserts had
to be removed as well. However, in practice the same asserts
are in place at a higher level as well (in `VArrayCommon`).
In most cases it is currently not used, so always having it there
causes unnecessary overhead. In my test file that causes
a 2 % performance improvement.
Previously, `ParamsBuilder` lazily allocated an array for an
output when it was unused, but the called multi-function
wanted to access it. Now, whether the multi-function supports
an output to be unused is part of the signature. This way, the
allocation can happen earlier when the parameters are build.
The benefit is that this makes all methods of `MFParams`
thread-safe again, removing the need for a mutex.
`std::get` could not be used due to restrictions on macos.
However, the minimum requirement has been lifted in
{rB597aecc01644f0063fa4545dabadc5f73387e3d3}.
Currently you can retrieve a mutable array from a const CustomData.
That makes code unsafe since the compiler can't check for correctness
itself. Fix that by introducing a separate function to retrieve mutable
arrays from CustomData. The new functions have the `_for_write`
suffix that make the code's intention clearer.
Because it makes retrieving write access an explicit step, this change
also makes proper copy-on-write possible for attributes.
Notes:
- The previous "duplicate referenced layer" functions are redundant
with retrieving layers with write access
- The custom data functions that give a specific index only have
`for_write` to simplify the API

Timecodes were generated from read packets, but applied to decoded

This way delay can be eliminated and timecode files are more reliable.
Effectively this disables two volume modifiers for the new curves
object and the point cloud object types. The aim is to simplify the
process of using these object types to prove out a node-group-based
workflow integrated with the asset browser. We're making the assumption
that these two modifiers were used very rarely on the new curves type
since that wasn't its purpose, so this breaks backwards compatibility.
Similar to the corresponding properties on node sockets, only adjust
the soft range. Because group nodes only have soft limits, groups
should generally be able to accept these inputs anyway. The benefit
of only using a soft range is that it allows choosing a more user-
friendly default range while keeping flexibility.
A proper boolean custom property type is commonly requested. This
commit simply adds a new `IDP_BOOLEAN` type that can be used for
boolean and boolean array custom properties. This can also be used
for exposing boolean node sockets in the geometry nodes modifier.
I've just extended the places existing IDProperty types are used, and
tested with the custom property edit operator and the python console.

Replace the pointers in the MeshEdge with indexes, removing MeshPrimitive and MeshVertex.
Code cleanup proposed by the geometry nodes to make the data structures more reusable by
other areas of Blender as well. Old implementation was to focused to the texture painting.
Initial the idea was to do the same with the data structures in UVIslands, but there some
concerns were raised that requires a different design than expected from a clean-up patch.
Concerns raised about converting UVIslands:
* Maps between UVPrimitive, UVEdge and UVVertex will be stored inside the UVIsland.
During UVIsland extraction detected islands can be merged. When they are merged all
Indexes should be updated.
* It is not possible to pre-allocate all buffers as they grow, what will lead to more re-allocations. The current
implementation uses a VectorList to ensure that re-allocations don't require the data to be
moved to the newly allocated memory. We could store some information about last used
sizes in runtime data to reduce the re-allocation overhead.
* Solution would require index based access inside a VectorList, which might increase the
complexity.
* UVIslands during 3d texturing is used as intermediate data, the final data is stored as PackedPixelRows.
We could proceed converting UVIslands as well, but that would lower the performance noticeably.
3D texturing has performance requirements, so when doing so we should make sure that
it matches that as well.

Some of the guiding parameters are now only shown if the `Experimental` features are active.
Problem is actually caused by
7619ec5c01
that removed the static define in rtcore_config.h
leading openpgl and blender both to assume we
were dealing with a dynamic embree which made
things rather unhappy at link time.
this adds a patch embree to generate a proper
rtcore_config.h header file again.
openpgl's build uses the embree config files which are
aware it is a static version of embree, but never
actually pass -DEMBREE_STATIC_LIB to openpgl's CXX flags,
resulting in the assumption that embree is dynamic,
which causes linker errors when we link it against
static embree in the final blender binary.
This patch adds path guiding features into Cycles
by integrating Intel®'s Open path guiding library
(Open PGL: https://github.com/OpenPathGuidingLibrary/openpgl).
The current implementation supports guiding directional sampling
decisions on surfaces, when the material contains a least one diffuse component,
and in volumes, with isotropic and anisotropic Henyey-Greenstein phase functions.
On surfaces, the guided sampling decision is proportional to the product of
the incident radiance and the normal-oriented cosine lobe and in volumes it
is proportional to the product of the incident radiance and the phase function.
The incident radiance field of a scene is learned and updated during rendering
after each per-frame rendering iteration/progression.
At the moment, path guiding is only supported by Cycles
CPU backend. Support for GPU backends will be added in
future versions of Open PGL.
To build Blender/Cycles with path guiding support, one only needs to enable
the CMake option `WITH_PATH_GUIDING`.
- tell the compiler to generate the _d postfix for debug
libs, rather than renaming the openpgl.lib to openpgl_d.lib
manually.
- enable the post install phase for windows.
- Small white space clean-up.
The new version of Embree supports to set the name of the TBB component (i.e., tbb_static) and fixes the dllexport/dllimport for the static builds under Windows.
As a result we do not need to patch the Embree cmake scripts and can use them as-is.
