Instead of allocating a vector of the basis weights cache for
each evaluated point, allocate a single vector for all of the
weights. This should reduce memory usage by avoiding the
overhead of storing many vectors. I noticed a small performance
improvement to evaluated position calculation with an order of 5,
which is larger than `Vector`'s default inline buffer capacity.
This change is possible because of previous commits that
made the basis cache for each evaluated point always have
the same "order" size.
Currently a single buffer is used as working space for all evaluated
points. In order to make evaluations more independent, opening
options like multi-threading in the future, instead use a separate
array for each call. Using an inline buffer capacity higher than
the default allows a few percent performance improvement, and removes
allocations for every evaluated point.
The step after calculating the NURBS basis for a single evaluated
point trimmed extra zeroes from the weights. However, in practice
this rarely did anything, only for the first and last evaluated point
of certain knot configurations. Remove it in order to simplify code.
Also use a separate span for the result, to clarify its length.
Add the ability to move `CurvesGeometry` without copying its attributes
and data. The benefit is more intuitive management of the data-block
copying, and less overhead for copying in some cases. The "moved-from"
source is left in an empty but valid state. A test file is added to test
the move constructor.
There was an error with the attribute API implementation for vertex
groups. If the vertex group layer referenced an original mesh, it wasn't
properly duplicated for writing.
It was possible that a render thread will be freeing cache while the
interface is iterating over cache items to build cache line.
Found while looking into T94738. It might be a fix, but I am unable
to reproduce the original issue, so can not know for sure whether
there is something else going or or not.
This function was copied from txt_sel_to_buf, including unnecessary
complexity to support selection as well as checks for the cursor
which don't make sense when copying the whole buffer.
Use a simple loop to copy all text into the destination buffer.
This patch enables all 8 combinations of Nurbs modes: Cyclic,
Bezier and Endpoint. Also removes restriction on Bezier Nurbs order.
The most significant changes are mode combinations bringing new
meaning. In D13891 is a scheme showing NURBS with same control
points in a modes, and also further description of each possible case.

Blender crashes when a multi-user grease pencil object has vertex
groups and is modified by modifiers, layer transform or parenting.
The fix makes sure that we copy the vertex group names list.

This commit fixes an issue, where for instance, when merging vertices
with the "Merge by Distance" geometry node, the resulting vertices had
their boolean attributes set unpredictably.
Boolean attributes are implemented as custom data, and when welding
vertices, the custom data for the resulting vertices comes from
interpolating the custom data of the source vertices.
This commit implements the missing interpolation function for the
boolean custom data type. This interpolation function is implemented in
terms of the logical or operation, that is to say, if any of the source
vertices (with a weight greater than zero) have the boolean set, the
boolean will also be set on the resulting vertex.
This logic matches 95981c9876.
In geometry nodes, attribute interpolation generally does not use the
CustomData API for performance reasons, but other areas of Blender
still do.

Sound properties like volume, pitch and muting are handled in
`BKE_sound_add_scene_sound()`. This is unnecessary, because in
properties are then set to real values in `SEQ_edit_update_muting()` and
`seq_update_seq_cb()`.
Alternatively, it may be better to remove all other updates leave them
in `BKE_sound_add_scene_sound()`. But I want to add muting per channel,
whhich is easier and probably cleaner to do with function
`SEQ_edit_update_muting()`.

Code cleaning up no-more-needed override data during diffing process
would systematically remove override data from linked IDs.
While this is not a critical issue in theory, it has bad consequences at
the very least on user UI/UX, and potentially can cause bugs in some
corner-cases scenarii.
Issue only happens in release builds on windows. That said it was an
actual error in the code. This class is compiled inline in release
builds. When updating multiple textures it would reuse the same memory
to collect the changes. When the previous loaded tilenumber was exactly the
same but from a different image the tile buffer wasn't loaded.

Annotation tool is used as a general mark tool for many add-ons. To be able to detect when an annotation is done is very handy to integrate the annotation tool in add-ons and other studio workflows.
The new callback names are: `annotation_pre` and `annotation_post`
Both callbacks are exposed via the Python module `bpy.app.handlers`
Example use:
```
import bpy
def annotation_starts(gpd):
print("Annotation starts")
def annotation_done(gpd):
print("Annotation done")
bpy.app.handlers.annotation_pre.clear()
bpy.app.handlers.annotation_pre.append(annotation_starts)
bpy.app.handlers.annotation_post.clear()
bpy.app.handlers.annotation_post.append(annotation_done)
```
Note: The handlers are called for any annotation tool, including eraser.

When a grease pencil data-block has multiple users and is subject
to modifiers, layer transforms or parenting, performance
(especially playback) is greatly affected.
This was caused by the grease pencil eval process which does per
instance full-copies of the original datablock in case those
kinds of transformations need to be applied.
This commit changes the behavior of the eval process to do shallow
copies (layers with empty frames) of the datablock instead
and duplicates only the visible strokes.
When we need to have a unique eval data
per instance, only copy the strokes of visible
frames to this copy.
Performance:
On a test file with 1350 frames 33k strokes and 480k points
in a single grease pencil object that was instanced 13 times:
- master: 2.8 - 3.3 fps
- patch: 42 - 52 fps

The "curve_type" was transferred to instances because it isn't a
built-in curve attribute. Then it was interpolated as a point
domain attribute from the instance domain in the realize
instances node.
The fix was just missing from 9ec12c26f1.
`curve_type` needs to be marked as a built-in attribute.
When removing a modifier, changing the layer transform or updating
the parent of a grease pencil object that has a multi-user datablock
and animation data, the eval data is not updated properly (after a
frame change). This can also cause memory leaks.
The fix makes sure that we free and reset any runtime copy
(`ob->runtime.gpd_eval`) in `BKE_gpencil_prepare_eval_data`.
Note: As far as we can tell, `ob->runtime.gpd_orig` is unused and could
be removed. The assignment in `BKE_gpencil_prepare_eval_data`
seemed to be unnecessary.

There are two issues revealed in the bug report:
- the GPU subdivision does not support meshes with only loose geometry
- the loose geometry is not subdivided
For the first case, checks are added to ensure we still fill the
buffers with loose geometry even if no polygons are present.
For the second case, this adds
`BKE_subdiv_mesh_interpolate_position_on_edge` which encapsulates the
loose vertex interpolation mechanism previously found in
`subdiv_mesh_vertex_of_loose_edge`.
The subdivided loose geometry is stored in a new specific data structure
`DRWSubdivLooseGeom` so as to not pollute `MeshExtractLooseGeom`. These
structures store the corresponding coarse element data, which will be
used for filling GPU buffers appropriately.
