Add a doc-string explaining the purpose of each call back and
how they should be used.
Also add a currently unused callback 'POST_FAIL' that is to be used in
cases the action fails - giving script authors, a guarantee that a
call to `pre` will always have a matching `post/post_fail` call.
- D11422: adds a callback that can use 'post_fail'.
- T88696: proposed these conventions.
This node is similar to the mask modifier, but it deletes the elements
of the geometry corresponding to the selection, which is retrieved as
a boolean attribute. The node currently supports both mesh and point
cloud data. For meshes, which elements are deleted depends on the
domain of the input selection attribute, just like how behavior depends
on the selection mode in mesh edit mode.
In the future this node will support curve data, and ideally volume
data in some way.

Metadata panel was visible in each category. In other editors, this
panel is usually placed in category with other source media properties.
In sequencer, metadata is transfered over while compositing and relation
to particular strip is lost, therefore separate category for metadata
seems to be best option. Since Metadata panel is alone in this category,
it will be open by default.
This commit skips the eager recalculation of mesh normals in the
transform node. Often another deformation or topology-altering
operation will happen after the transform node, which means the
recalculation was redundant anyway.
In one of my test cases this made the node more than 14x faster.
Though depending on the situation the cost of updating the normals
may just be shifted elsewhere.
This was reported for the special case of mapping with "Strand /
Particle" coords, but was not working with other coordinates either.
Dont see a reason for not supporting Size influence textures for these
kinds of particles (and since these types of particles have an "age"
like all others as well, even the "Strand / Particle" coords are
supported here as well)

This fixes T88455 by adding an empty material slot to newly
generated meshes. This allows the object to overwrite the
"default" material without any extra nodes. Technically,
all polygons reference the material index 0 already, so it
makes sense to add a material slot for this material index.

`bvhtree_from_mesh_edges_create_tree` can actually leave the BVHTree
NULL (e.g. if no edges are present).
Now dont allocate `BVHTreeFromMesh` on the `SurfaceModifierData` at all
in case the tree would be NULL anyways.
Places like `get_effector_data` check for `SurfaceModifierData`-
>`BVHTreeFromMesh` and dont try to stuff like getting a closest point on
surface, which would crash as soon as BVHNodes would need to be accessed
(from the NULL BVHTree).

This commit fixes two different issues:
* In some cases, when an object was added to a sub-collection and used
into a different subcollection, and the root common collection would
not need to be resynced, it would end up creating multiple overrides
of the new object. This was affecting both normal and recursive
resync.
* In recurisve resync case, the barrier code to define what is part or
not of a override group/hierarchy was wrong.
Note that the current solution for the first issue is sub-optimal (it
goes back to the root of the override hierarchy and resync the whole
thing), a better solution is TODO for now.
This function would considere that there was a name conflict even in
case existing ID would be a linked one.
This is only a (symbolic) perforance improvement and logical fix, since
`BKE_id_new_name_validate` would not do that mistake anyway.
This is mandatory for liboverride resync, since this feature may imply
we have to create linked overrides in libraries, and there may be
several copies of those.
This is also a first step to a more general support of IDmanagement-editing
library data.
Note that this commit should have absolutely no effect on current code,
as the only function allowed to check unique names for linked IDs
currently is `BKE_libblock_management_main_add`, which is unused.
This commit also adds some basic testing for `BKE_id_new_name_validate`.
This patch adds the base code needed to make the full-frame system work for both current tiled/per-pixel implementation of operations and full-frame.
Two execution models:
- Tiled: Current implementation. Renders execution groups in tiles from outputs to input. Not all operations are buffered. Runs the tiled/per-pixel implementation.
- FullFrame: All operations are buffered. Fully renders operations from inputs to outputs. Runs full-frame implementation of operations if available otherwise the current tiled/per-pixel. Creates output buffers on first read and free them as soon as all its readers have finished, reducing peak memory usage of complex/long trees. Operations are multi-threaded but do not run in parallel as Tiled (will be done in another patch).
This should allow us to convert operations to full-frame in small steps with the system already working and solve the problem of high memory usage.
FullFrame breaking changes respect Tiled system, mainly:
- Translate, Rotate, Scale, and Transform take effect immediately instead of next buffered operation.
- Any sampling is always done over inputs instead of last buffered operation.

2 sided faces aren't supported and will cause problems in many areas
of Blender's code.
Removing (implied) support for faces with fewer than 3 sides
means the total number of triangles is known ahead of time.
This simplifies adding support for multi-threading and partial updates
to an existing tessellation - as the face and loop indices can be used
to access the range of triangles associated with a face.
Also correct outdated comments.

This is from patch D11432 from Erik Abrahamsson. He found that
in some mpq3 functions called frequently from loops, passing in
buffers for termporary mpq3 values can save substantial time.
On my machine, his example in that patch went from 9.48s to 7.50s
for the boolean part of the calculation. On his machine, a running
time went from 17s to 10.3s.
The fseek() function on Windows only accepts a 32-bit long offset
argument. Because of this we have our own version, BLI_fseek(), which
will use 64-bit _fseeki64() on Windows. This patch just replaces some
fseek() calls with BLI_fseek().

bf_bmesh historically always build with the /WX flag
on windows making all warnings errors, somewhere along
the way this has broken for msbuild, ninja still exhibits
the expected behaviour.
The flags are still passed to the target, and I've validated
they are there when the add_library call fires, but they
somehow never make it to the generated msbuild project files.
I suspect this is a cmake bug but I'm seemingly unable
to extract a repro case to file a bug upstream.
Setting the same options target_compile_options seems to work,
I'm not happy about the unexplained nature of the breakage
but this will have to do for now.
This patch replaces / redoes the entire MeshExtractors system.
Although they were useful and facilitated the addition of new buffers, they made it difficult to control the threads and added a lot of threading overhead.
Part of the problem was in traversing the same loop type in different threads. The concurrent access of the BMesh Elements slowed the reading.
This patch simplifies the use of threads by merging all the old callbacks from the extracts into a single series of iteration functions.
The type of extraction can be chosen using flags.
This optimized the process by around 34%.

Cause is that initializing the cryptomatte session would reset the
current frame of an image sequence. The solution is to always use the
scene current frame so it resets to the correct frame.
This was a todo that wasn't solved after it landed in master.
Needs to be backported to 2.93.
When compositor node tree has a texture node, TextureOperation vector inputs has always {0, 0} resolution instead of having same resolution as TextureOperation which is the expected behaviour for resolutions propagation.
Current TextureOperation determineResolution implementation doesn't determine inputs resolution, breaking propagation of preferred resolution and that's the reason why they are always 0. Setting scene resolution always would mean it is its own resolution and could make sense, but setting it only when preferred resolution is 0, breaks preferred resolution logic affecting other operations as explained in D10972. In any case scene resolution is already the default preferred resolution on viewer and compositor nodes.

The issue was two fold. We didn't properly:
1. Initialize the codec default values which would lead to VLC
complaining because of garbage/wrong codec settings.
2.Calculate the time base for the video. FFmpeg would happily accept
this but VLC seems to assume the time base value is at least somewhat
correct and couldn't properly display the frames as the internal time
base was huge. We are talking about 90k ticks (tbn) for one second of
video!
This patch initializes all codecs to use their default values and fixes
the time base calculation so it follows the guidelines from ffmpeg.
