This change applies only for automatic proxy building, when strip

Don't build proxy file if movie is already fast enough to seek.
To determine seek performance, check if whole GOP can be decoded
in 100 milliseconds.
To consider some variation in GOP size, large number of packets are
read, assuming that each packet will produce 1 frame. While this is not
technically correct, it does give quite accurate estimate of maximum GOP
size.
This test will ensure consistent performance on wide array of machines.

This commit moves the weld modifier code to the geometry module
so that it can be used in the "Merge by Distance" geometry node
from ec1b0c2014. The "All" mode is exposed in the node
for now, though we could expose the "Connected" mode in the future.
The modifier itself is responsible for creating the selections from
the vertex group. The "All" mode takes an `IndexMask` for the
selection, and the "Connected" mode takes a boolean array,
since it actually iterates over all edges.
Some disabled code for a BVH mode has not been copied over,
it's still accessible through the patches and git history anyway,
and it made the port slightly simpler.

Previously it was only part of experimental features in beta, however now
renderers can render point clouds generated by geometry nodes. Adding or
converting a point cloud object directly is still hidden by default, since
there is no good way to edit it.
This implements a merge by distance operation for point clouds.
Besides the geometry input, there are two others-- a selection
input to limit the operation to certain points, and the merge
distance. While it would be a reasonable feature, the distance
does not support a field currently, since that would make
the algorithm significantly more complex.
All attributes are merged to the merged points, with the values
mixed together. This same generic method is used for all attributes,
including `position`. The `id` attribute uses the value from the
first merged index for each point.
For the implementation, most of the effort goes into creating a
merge map to speed up attribute mixing. Some parts are inherently
single-threaded, like finding the final indices accounting for the
merged points. By far most of the time is spend balancing the
KD tree.
Mesh support will be added in the next commit.

Movies with variable frame rate can cause mismatch of displayed frame
when proxies are used. Since proxies are not used for rendering, this
means, that output may be different than expected. This problem can be
avoided when timecodes are used.
Set used timecode to Record Run. Timecodes are built with proxies at
the same time, therefore if proxies are built and used this will
resolve possible mismatch of output.
Record run is chosen, because it will show frames based on time they
were encoded by encoder and should match behavior as if movie was
played back at normal speed. This change is done only for new strips
in order to not overwrite user defined settings.
Other minor changes:
- When proxies are enabled, size 25% is no longer set by default. It was mostly annoying anyway.
- Silence warning when timecode file is not present. This was introduced in 4adbe31e2f.
Previously use of timecodes was hard-coded in sequencer and this error would spam console if timecodes would be
enabled by default and proxies would be never built.

During sprite fright loading of complex scenes would spend a long time in remapping ID's
The remapping process is done on a per ID instance that resulted in a very time consuming

If there are N of references to ID blocks and there are M ID blocks that needed to be remapped
it would take N*M checks. These checks are scattered around the place and memory.
Each reference would only be updated at most once, but most of the time no update is needed at all.

This would only require N checks. Additional benefits is improved data locality as data is only loaded once

The evaluated mesh is a result of evaluated modifiers, and referencing
other evaluated IDs such as materials.
It can not be stored in the EditMesh structure which is intended to be
re-used by many areas. Such sharing was causing ownership errors causing
bugs like
T93855: Cycles crash with edit mode and simultaneous viewport and final render
The proposed solution is to store the evaluated edit mesh and its cage in
the object's runtime field. The motivation goes as following:
- It allows to avoid ownership problems like the ones in the linked report.
- Object level is chosen over mesh level is because the evaluated mesh
is affected by modifiers, which are on the object level.
This patch allows to have modifier stack of an object which shares mesh with
an object which is in edit mode to be properly taken into account (before
the change the modifier stack from the active object will be used for all
objects which share the mesh).
There is a change in the way how copy-on-write is handled in the edit mode to
allow proper state update when changing active scene (or having two windows
with different scenes). Previously, the copt-on-write would have been ignored
by skipping tagging CoW component. Now it is ignored from within the CoW
operation callback. This allows to update edit pointers for objects which are
not from the current depsgraph and where the edit_mesh was never assigned in
the case when the depsgraph was evaluated prior the active depsgraph.
There is no user level changes changes expected with the CoW handling changes:
should not affect on neither performance, nor memory consumption.
Tested scenarios:
- Various modifiers configurations of objects sharing mesh and be part of the
same scene.
- Steps from the reports: T93855, T82952, T77359

This patch checks for this case and outputs a descriptive error message if
a particular createInfo merge error is founds.
Other validation can be added later.
This patch introduces an extrude node with three modes. The vertex mode
is quite simple, and just attaches new edges to the selected vertices.
The edge mode attaches new faces to the selected edges. The faces mode
extrudes patches of selected faces, or each selected face individually,
depending on the "Individual" boolean input.
The default value of the "Offset" input is the mesh's normals, which
can be scaled with the "Offset Scale" input.
**Attribute Propagation**
Attributes are transferred to the new elements with specific rules.
Attributes will never change domains for interpolations. Generally
boolean attributes are propagated with "or", meaning any connected
"true" value that is mixed in for other types will cause the new value
to be "true" as well. The `"id"` attribute does not have any special
handling currently.
Vertex Mode
- Vertex: Copied values of selected vertices.
- Edge: Averaged values of selected edges. For booleans, edges are
selected if any connected edges are selected.
Edge Mode
- Vertex: Copied values of extruded vertices.
- Connecting edges (vertical): Average values of connected extruded
edges. For booleans, the edges are selected if any connected
extruded edges are selected.
- Duplicate edges: Copied values of selected edges.
- Face: Averaged values of all faces connected to the selected edge.
For booleans, faces are selected if any connected original faces
are selected.
- Corner: Averaged values of corresponding corners in all faces
connected to selected edges. For booleans, corners are selected
if one of those corners are selected.
Face Mode
- Vertex: Copied values of extruded vertices.
- Connecting edges (vertical): Average values of connected selected
edges, not including the edges "on top" of extruded regions.
For booleans, edges are selected when any connected extruded edges
were selected.
- Duplicate edges: Copied values of extruded edges.
- Face: Copied values of the corresponding selected faces.
- Corner: Copied values of corresponding corners in selected faces.
Individual Face Mode
- Vertex: Copied values of extruded vertices.
- Connecting edges (vertical): Average values of the two neighboring
edges on each extruded face. For booleans, edges are selected
when at least one neighbor on the extruded face was selected.
- Duplicate edges: Copied values of extruded edges.
- Face: Copied values of the corresponding selected faces.
- Corner: Copied values of corresponding corners in selected faces.
**Differences from edit mode**
In face mode (non-individual), the behavior can be different than the
extrude tools in edit mode-- this node doesn't handle keeping the back-
faces around in the cases that the edit mode tools do. The planned
"Solidify" node will handle that use case instead. Keeping this node
simpler and faster is preferable at this point, especially because that
sort of "smart" behavior is not that predictable and makes less sense
in a procedural context.
In the future, an "Even Offset" option could be added to this node
hopefully fairly simply. For now it is left out in order to keep
the patch simpler.
**Implementation**
For the implementation, the `Mesh` data structure is used directly
rather than converting to `BMesh` and back like D12224. This optimizes
for large extrusion operations rather than many sequential extrusions.
While this is potentially more verbose, it has some important benefits:
First, there is no conversion to and from `BMesh`. The code only has
to fill arrays and it can do that all at once, making each component of
the algorithm much easier to optimize. It also makes the attribute
interpolation more explicit, and likely faster. Only limited topology
maps must be created in most cases.
While there are some necessary loops and allocations with the size of
the entire mesh, I tried to keep everything I could on the order of the
size of the selection rather than the size of the mesh. In that respect,
the individual faces mode is the best, since there is no topology
information necessary, and the amount of work just depends on the size
of the selection.
Modifying an existing mesh instead of generating a new one was a bit
of a toss-up, but has a few potential benefits:
- Avoids manually copying over attribute data for original elements.
- Avoids some overhead of creating a new mesh.
- Can potentially take advantage of future ammortized mesh growth.
This could be changed easily if it turns out to be the wrong choice.

Editing of generic attributes on the original objects in edit modes is

This adds vertex creasing support for OpenSubDiv for modeling, rendering,

For modeling, vertex creasing follows the edge creasing implementation with an
operator accessible through the Vertex menu in Edit Mode, and some parameter in

creasing also affects vertex creasing.
The vertex crease data is stored as a CustomData layer, unlike edge creases
which for now are stored in `MEdge`, but will in the future also be moved to
a `CustomData` layer. See comments for details on the difference in behavior
for the `CD_CREASE` layer between egdes and vertices.
For Cycles this adds sockets on the Mesh node to hold data about which vertices
are creased (one socket for the indices, one for the weigths).
Viewport rendering of vertex creasing reuses the same color scheme as for edges
and creased vertices are drawn bigger than uncreased vertices.

original curves are moved into temporary `ListBase` and curves in
clipboard are moved into scene action. This is because when strips from
clipboard have to be renamed, function `SEQ_ensure_unique_name()` does
fix RNA paths of curves, but this is done globally for all curves within
action. After strips are renamed, restore original curves from backup.
Note: This patch handles only fcurves. Drivers and actions are currently
not handled anywhere in VSE.

This merge the description into one struct only that can be more easily
copied during `finalize()`.
The in and out layout parameters are better named and extended with the
invocation count (with fallback support)
Route cause was data alignment mismatch between GPU and CPU. This
mismatch would not allow us to bind the UBO where data wasn't available
on the GPU.
Fixed by using float4 in stead of float2. This could eventually be
packed, but that would lead to less readable code.
Cause was incorrect logic when generating the resource layout. It the
explicit_location_support setting was ignored and the binding were
generated for image, uniform buffers and storage buffers.
- Add BM_mesh_debug_print & BM_mesh_debug_info.
- Report flags in Mesh.cd_flag in BKE_mesh_debug_print
- Move custom data printing into customdata.cc (noted as a TODO).
Note that the term "runtime" has been removed from
`BKE_mesh_runtime_debug_print` since these are useful for debugging any
kind of mesh data.
Code that handled merging & initializing custom-data from other
meshes sometimes missed checks for this flag, causing bevel weights to
lost when the mesh was converted to a BMesh.
The following changes are a more general fix for T94197.
- Add BM_mesh_copy_init_customdata_from_mesh_array which initializes
custom-data from multiple meshes at once.
As well as initializing custom-data layers from Mesh.cd_flag.
This isn't essential for boolean, however it avoids the overhead of
resizing custom-data layers.
- Loading mesh data into a BMesh now respects Mesh.cd_flag
instead of only checking if the BMesh custom-data-layer exists.
Without this, the order of meshes passed to BM_mesh_bm_from_me could
give different (incorrect) results.
- Copying mesh data now copies `cd_flag` too. This is a precaution
as in my tests evaluating modifiers these values always matched.
Nevertheless it's correct to copy this value as custom-data it's
self is being copied.
The buffer passed as an argument to `GPUFrameBuffer.read_color` is used
in the return of the function and therefore, if not used, its refcount is
decremented.
So be sure to increment the refcount of the already existing objects that
will be used in the return of a function.
This was the case for multi input sockets that have a link already.
Since we have multi input sockets, the way we use `socket_is_available`
is not really giving the expected result on these.
When used for input sockets the intention is to find a free socket
(either for noodle **replacement**, then it is always available, or just
the next free available socket).
Now I would think without the intention to replace an existing link, a
multi input socket should still be available.
From the inside of the function, the `replace` argument turns [namewise]
to `allow_used`, which sounds a little different (so one might argue
that if `allow_used` is `False` this should also trigger for already
connected multi input sockets).
In the end, this is an issue with the variable naming though, cant think
of a usecase where the patch change would really go against intentions.

Bug possibly introduced in {rBc57e4418bb85aec8bd3615fd775b990badb43d30}.
Interestingly, the orientation set before (NORMAL), even different from
the orientation that was actually used, was allowing the use of
"orient_matrix" ("orient_matrix_type" should have been NORMAL in that

In any case, make sure the "orient_matrix_type" and "orient_type" are the
same so that the "orient_matrix" is used.
These operations (sorting and selecting all nodes) should generally
be handled by the node editor and not outside code. They were not
called outside of the node editor, so they can be moved to the editor's
`intern` header.
This file was added nine years ago, and was unused then.
Now with active tools we use a different approach to create
toolbars, so the file is not relevant.
This node allows accessing data of other elements in the context geometry.
It is similar to the Transfer Attribute node in Index mode. The main difference
is that this node does not require a geometry input, because the context
is used.
The node can e.g. be used to generalize what the Edge Vertices node is doing.
Instead of only being able to get the position of the vertices of an edge,
any field/attribute can be accessed on the vertices.

Adds a second output to the edge angle node that shows the signed angle
between the two faces, where Convex angles are positive and Concave angles

In this special case the flat uniform vector cannot be used anymore as it

| IDProperty.value | ArrayValue | When type is IDP_GROUP. Recursively uses the same structure as described in this section. |
| IDProperty.value | ArrayValue | When type is IDP_ARRAY. Each element holds a single element as described in this section. |
NOTE: IDP_ID and IDP_IDARRAY aren't supported. The entry will not be added.

```
## Considered alternatives ##
- Add conversion functions inside `asset_indexer`; makes generic code part of a specific solution.
- Add conversion functions inside `BLI_serialize`; would add data transformation responsibilities inside a unit that is currently only responsible for formatting.
- Use direct mapping between IDP properties and Values; leads to missing information and edge cases (empty primitive arrays) that could not be de-serialized.

Override layers are a standard feature of Alembic, where archives can override
data from other archives, provided that the hierarchies match.
This is useful for modifying a UV map, updating an animation, or even creating
some sort of LOD system where low resolution meshes are swapped by high resolution
versions.
It is possible to add UV maps and vertex colors using this system, however, they
will only appear in the spreadsheet editor when viewing evaluated data, as the UV
map and Vertex color UI only show data present on the original mesh.
Implementation wise, this adds a `CacheFileLayer` data structure to the `CacheFile`
DNA, as well as some operators and UI to present and manage the layers. For both
the Alembic importer and the Cycles procedural, the main change is creating an
archive from a list of filepaths, instead of a single one.
After importing the base file through the regular import operator, layers can be added

The crash is due to the fact that GPU subdivision extraction routines
for edit data (including UVs) only worked for BMesh. However, a Mesh
based version is still needed for texture painting. This adds the
missing components. This also ensures all data are properly initialized
(at least the ones revealed by the bug).
This puts the loop over the final subdivision quads outside of the mesh
iteration callback. This can also allow for easier parallel execution in
the future if need be.
Conceptually, this is the geometry that data is taken from,
not the target of an operation, so rename it from "Target"

Before rB644e6c7a3e99ae1d43ed, `fill` was used in the error

The mask is only used if it's not zero. Adding the normal mask made
it not zero, but it didn't include anything else, so all custom data
layers except normals were removed. The fix is to only add normals
to the mask when it should be used.
As described in T91186, this commit moves mesh vertex normals into a
contiguous array of float vectors in a custom data layer, how face
normals are currently stored.
The main interface is documented in `BKE_mesh.h`. Vertex and face
normals are now calculated on-demand and cached, retrieved with an
"ensure" function. Since the logical state of a mesh is now "has
normals when necessary", they can be retrieved from a `const` mesh.
The goal is to use on-demand calculation for all derived data, but
leave room for eager calculation for performance purposes (modifier
evaluation is threaded, but viewport data generation is not).
**Benefits**
This moves us closer to a SoA approach rather than the current AoS
paradigm. Accessing a contiguous `float3` is much more efficient than
retrieving data from a larger struct. The memory requirements for
accessing only normals or vertex locations are smaller, and at the
cost of more memory usage for just normals, they now don't have to
be converted between float and short, which also simplifies code
In the future, the remaining items can be removed from `MVert`,
leaving only `float3`, which has similar benefits (see T93602).
Removing the combination of derived and original data makes it
conceptually simpler to only calculate normals when necessary.
This is especially important now that we have more opportunities
for temporary meshes in geometry nodes.
**Performance**
In addition to the theoretical future performance improvements by
making `MVert == float3`, I've done some basic performance testing
on this patch directly. The data is fairly rough, but it gives an idea
about where things stand generally.
- Mesh line primitive 4m Verts: 1.16x faster (36 -> 31 ms),
showing that accessing just `MVert` is now more efficient.
- Spring Splash Screen: 1.03-1.06 -> 1.06-1.11 FPS, a very slight
change that at least shows there is no regression.
- Sprite Fright Snail Smoosh: 3.30-3.40 -> 3.42-3.50 FPS, a small
but observable speedup.
- Set Position Node with Scaled Normal: 1.36x faster (53 -> 39 ms),
shows that using normals in geometry nodes is faster.
- Normal Calculation 1.6m Vert Cube: 1.19x faster (25 -> 21 ms),
shows that calculating normals is slightly faster now.
- File Size of 1.6m Vert Cube: 1.03x smaller (214.7 -> 208.4 MB),
Normals are not saved in files, which can help with large meshes.
As for memory usage, it may be slightly more in some cases, but
I didn't observe any difference in the production files I tested.
**Tests**
Some modifiers and cycles test results need to be updated with this
commit, for two reasons:
- The subdivision surface modifier is not responsible for calculating
normals anymore. In master, the modifier creates different normals
than the result of the `Mesh` normal calculation, so this is a bug
fix.
- There are small differences in the results of some modifiers that
use normals because they are not converted to and from `short`
anymore.
**Future improvements**
- Remove `ModifierTypeInfo::dependsOnNormals`. Code in each modifier
already retrieves normals if they are needed anyway.
- Copy normals as part of a better CoW system for attributes.
- Make more areas use lazy instead of eager normal calculation.
- Remove `BKE_mesh_normals_tag_dirty` in more places since that is
now the default state of a new mesh.
- Possibly apply a similar change to derived face corner normals.

There were a couple of function name collisions which were caused
by sharing code with the mask modifier. I just removed the dependence
on the mask modifier now. The code that I duplicated for that purpose
is only in a legacy node, so it can be expected to be removed soonish.
The fundamental limitation is that we can only have one instance
("dupli") generator at a time. Because the mesh output of a curve
object is output as an instances, the geometry set instances existed,
replacing the object as font instances. The "fix" is to reverse the
order. The behavior won't be perfect still, but at least the old
behavior will be preserved, which is really what matters for a
feature like this.
One way to take this change further would be completely disabling
regular geometry evaluation while this option is active. However,
it doesn't seem like that would actually improve the state of the code.

This patch implements the vector types (i.e:`float2`) by making heavy
usage of templating. All vector functions are now outside of the vector
classes (inside the `blender::math` namespace) and are not vector size
dependent for the most part.
In the ongoing effort to make shaders less GL centric, we are aiming
to share more code between GLSL and C++ to avoid code duplication.
####Motivations:
- We are aiming to share UBO and SSBO structures between GLSL and C++.
This means we will use many of the existing vector types and others
we currently don't have (uintX, intX). All these variations were
asking for many more code duplication.
- Deduplicate existing code which is duplicated for each vector size.
- We also want to share small functions. Which means that vector
functions should be static and not in the class namespace.
- Reduce friction to use these types in new projects due to their
incompleteness.
- The current state of the `BLI_(float|double|mpq)(2|3|4).hh` is a
bit of a let down. Most clases are incomplete, out of sync with each
others with different codestyles, and some functions that should be
static are not (i.e: `float3::reflect()`).
####Upsides:
- Still support `.x, .y, .z, .w` for readability.
- Compact, readable and easilly extendable.
- All of the vector functions are available for all the vectors types
and can be restricted to certain types. Also template specialization
let us define exception for special class (like mpq).
- With optimization ON, the compiler unroll the loops and performance
is the same.
####Downsides:
- Might impact debugability. Though I would arge that the bugs are
rarelly caused by the vector class itself (since the operations are
quite trivial) but by the type conversions.
- Might impact compile time. I did not saw a significant impact since
the usage is not really widespread.
- Functions needs to be rewritten to support arbitrary vector length.
For instance, one can't call `len_squared_v3v3` in
`math::length_squared()` and call it a day.
- Type cast does not work with the template version of the `math::`
vector functions. Meaning you need to manually cast `float *` and
`(float *)[3]` to `float3` for the function calls.
i.e: `math::distance_squared(float3(nearest.co), positions[i]);`
- Some parts might loose in readability:
`float3::dot(v1.normalized(), v2.normalized())`
becoming
`math::dot(math::normalize(v1), math::normalize(v2))`
But I propose, when appropriate, to use
`using namespace blender::math;` on function local or file scope to
increase readability.
`dot(normalize(v1), normalize(v2))`
####Consideration:
- Include back `.length()` method. It is quite handy and is more C++
oriented.
- I considered the GLM library as a candidate for replacement. It felt
like too much for what we need and would be difficult to extend / modify
to our needs.
- I used Macros to reduce code in operators declaration and potential
copy paste bugs. This could reduce debugability and could be reverted.
- This touches `delaunay_2d.cc` and the intersection code. I would like
to know @howardt opinion on the matter.
- The `noexcept` on the copy constructor of `mpq(2|3)` is being removed.
But according to @JacquesLucke it is not a real problem for now.

This patch implements the vector types (i.e:`float2`) by making heavy
usage of templating. All vector functions are now outside of the vector
classes (inside the `blender::math` namespace) and are not vector size
dependent for the most part.
In the ongoing effort to make shaders less GL centric, we are aiming
to share more code between GLSL and C++ to avoid code duplication.
####Motivations:
- We are aiming to share UBO and SSBO structures between GLSL and C++.
This means we will use many of the existing vector types and others
we currently don't have (uintX, intX). All these variations were
asking for many more code duplication.
- Deduplicate existing code which is duplicated for each vector size.
- We also want to share small functions. Which means that vector
functions should be static and not in the class namespace.
- Reduce friction to use these types in new projects due to their
incompleteness.
- The current state of the `BLI_(float|double|mpq)(2|3|4).hh` is a
bit of a let down. Most clases are incomplete, out of sync with each
others with different codestyles, and some functions that should be
static are not (i.e: `float3::reflect()`).
####Upsides:
- Still support `.x, .y, .z, .w` for readability.
- Compact, readable and easilly extendable.
- All of the vector functions are available for all the vectors types
and can be restricted to certain types. Also template specialization
let us define exception for special class (like mpq).
- With optimization ON, the compiler unroll the loops and performance
is the same.
####Downsides:
- Might impact debugability. Though I would arge that the bugs are
rarelly caused by the vector class itself (since the operations are
quite trivial) but by the type conversions.
- Might impact compile time. I did not saw a significant impact since
the usage is not really widespread.

Fixes issue T94603
It adds a new compositor node called Scene Time which is already present as a geo node, having the same basic nodes available in all node trees is a nice thing to have.
Renames "Time" node to "Time Curve", this is done to avoid confusion between the Time node and the Scene Time node.

The issue was caused by rBd09b1d2759861aa012ab2e7e4ce2ffa2.
Since this commit, the image users in gpu materials were updated
during depsgraph evaluation as well. However, there was a race
condition when one thread is deleting gpu materials in `BKE_material_eval`
while another thread is updating the image users at the same time.
The solution is to make sure that deleting gpu materials is done before
iterating over all gpu materials, by adding a new depsgraph relation.
The main issue was the use of `G_MAIN` during file load.
This patch refactors the code so that iterating over `G_MAIN`
is not necessary anymore. See D13800 for more details.

The issue was caused by Cycles display driver not being able to restore
window's OpenGL context after disposing Cycles-side OpenGL context.
This is due to the window OpenGL re-activation needing to access window
manager which gets cleared out form global main during file reading.
Defer clearing window manager from the global main to until after all
screens are "exited". This allows Cycles to properly stop rendering,
dispose its OpenGL context, and restore window's drawable context.
It is unclear why it was required to clear window manager list early
on. Guess is that it comes from an original code in a1c8543f2a where
there was an early return which then got replaced with an actual logic
without changing the order of de-initialization and window manager list
clear.

The direct cause of the bug in question was passing in the raw memory
buffer to sscanf. It should be called with a null-terminated buffer;
which isn't guaranteed when blindly trusting the file data.

our UNUSED macro is essentially a no-op for MSVC, which lead to
the situation where this well meant macro was emitting the

in cpp files.
This changes cleans up the use of the UNUSED macro in the
