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.

Currently the `MLoopUV` struct stores UV coordinates and flags related
to editing UV maps in the UV editor. This patch changes the coordinates
to use the generic 2D vector type, and moves the flags into three
separate boolean attributes. This follows the design in T95965, with
the ultimate intention of simplifying code and improving performance.
Importantly, the change allows exporters and renderers to use UVs
"touched" by geometry nodes, which only creates generic attributes.
It also allows geometry nodes to create "proper" UV maps from scratch,
though only with the Store Named Attribute node for now.
The new design considers any 2D vector attribute on the corner domain
to be a UV map. In the future, they might be distinguished from regular
2D vectors with attribute metadata, which may be helpful because they
are often interpolated differently.
Most of the code changes deal with passing around UV BMesh custom data
offsets and tracking the boolean "sublayers". The boolean layers are
use the following prefixes for attribute names: vert selection: `.vs.`,
edge selection: `.es.`, pinning: `.pn.`. Currently these are short to
avoid using up the maximum length of attribute names. To accommodate
for these 4 extra characters, the name length limit is enlarged to 68
bytes, while the maximum user settable name length is still 64 bytes.
Unfortunately Python/RNA API access to the UV flag data becomes slower.
Accessing the boolean layers directly is be better for performance in
general.
Like the other mesh SoA refactors, backward and forward compatibility
aren't affected, and won't be changed until 4.0. We pay for that by
making mesh reading and writing more expensive with conversions.

**Changes**
As described in T93602, this patch removes all use of the `MVert`
struct, replacing it with a generic named attribute with the name
`"position"`, consistent with other geometry types.
Variable names have been changed from `verts` to `positions`, to align
with the attribute name and the more generic design (positions are not
vertices, they are just an attribute stored on the point domain).
This change is made possible by previous commits that moved all other
data out of `MVert` to runtime data or other generic attributes. What
remains is mostly a simple type change. Though, the type still shows up
859 times, so the patch is quite large.
One compromise is that now `CD_MASK_BAREMESH` now contains
`CD_PROP_FLOAT3`. With the general move towards generic attributes
over custom data types, we are removing use of these type masks anyway.
**Benefits**
The most obvious benefit is reduced memory usage and the benefits
that brings in memory-bound situations. `float3` is only 3 bytes, in
comparison to `MVert` which was 4. When there are millions of vertices
this starts to matter more.
The other benefits come from using a more generic type. Instead of
writing algorithms specifically for `MVert`, code can just use arrays
of vectors. This will allow eliminating many temporary arrays or
wrappers used to extract positions.
Many possible improvements aren't implemented in this patch, though
I did switch simplify or remove the process of creating temporary
position arrays in a few places.
The design clarity that "positions are just another attribute" brings
allows removing explicit copying of vertices in some procedural
operations-- they are just processed like most other attributes.
**Performance**
This touches so many areas that it's hard to benchmark exhaustively,
but I observed some areas as examples.
* The mesh line node with 4 million count was 1.5x (8ms to 12ms) faster.
* The Spring splash screen went from ~4.3 to ~4.5 fps.
* The subdivision surface modifier/node was slightly faster
RNA access through Python may be slightly slower, since now we need
a name lookup instead of just a custom data type lookup for each index.
**Future Improvements**
* Remove uses of "vert_coords" functions:
* `BKE_mesh_vert_coords_alloc`
* `BKE_mesh_vert_coords_get`
* `BKE_mesh_vert_coords_apply{_with_mat4}`
* Remove more hidden copying of positions
* General simplification now possible in many areas
* Convert more code to C++ to use `float3` instead of `float[3]`
* Currently `reinterpret_cast` is used for those C-API functions

The 'Only Show Selected' filter button is far away from the Operator buttons in the User Interface Header, so it's difficult to make the association.

The Blur Attribute node mixes values of neighboring elements in meshes and curves.
Currently it supports points, edges and faces on meshes and points on curves.
In theory, support for face corners could be added, but useful semantics are not
obvious yet.
The node calculates a weighted average of each element with its neighbors (based
on curve/mesh topology). The weight of the element itself is always 1, and the weight
of the neighbor elements is controlled by the weight input socket. In the future,
more options for how different elements are weight can be added (e.g. smoothing
groups and selection).
The node can perform multiple blurring iterations to achieve a blurrier result.
Generally, it is better to do multiple iterations in one node instead of using
multiple blur nodes because it has better performance in the current implementation.
We use the term "Blur" (instead of "Smooth") because smoothing is generally more
related to removing roughness from surfaces. When viewing the result of the
Blur Attribute node in the viewport, it looks like an image is blurred. While the
node can also be used to smooth surfaces, other/better algorithms exists for that
purpose (which e.g. don't reduce the volume of the mesh to zero with too many
iterations).

**Problem**:
Area lights in Cycles have spread angle, in which case some part of the area light might be invisible to a shading point. The current implementation samples the whole area light, resulting some samples invisible and thus simply discarded. A technique is applied on rectangular light to sample a subset of the area light that is potentially visible (rB3f24cfb9582e1c826406301d37808df7ca6aa64c), however, ellipse (including disk) area lights remained untreated. The purpose of this patch is to apply a techniques to ellipse area light.
**Related Task**:
T87053
**Results**:
These are renderings before and after the patch:
|16spp|Disk light|Ellipse light|Square light (for reference, no changes)
|Before|{F13996789}|{F13996788}|{F13996822}
|After|{F13996759}|{F13996787}|{F13996852}
**Explanation**:
The visible region on an area light is found by drawing a cone from the shading point to the plane where the area light lies, with the aperture of the cone being the light spread.
{F13990078,height=200}
Ideally, we would like to draw samples only from the intersection of the area light and the projection of the cone onto the plane (forming a circle). However, the shape of the intersection is often irregular and thus hard to sample from directly.
{F13990104,height=200}
Instead, the current implementation draws samples from the bounding rectangle of the intersection. In this case, we still end up with some invalid samples outside of the circle, but already much less than sampling the original area light, and the bounding rectangle is easy to sample from.
{F13990125}
The above technique is only applied to rectangle area lights, ellipse area light still suffers from poor sampling. We could apply a similar technique to ellipse area lights, that is, find the
smallest regular shape (rectangle, circle, or ellipse) that covers the intersection (or maybe not the smallest but easy to compute).
For disk area light, we consider the relative position of both circles. Denoting `dist` as the distance between the centre of two circles, and `r1`, `r2` their radii. If `dist > r1 + r2`, the area light is completely invisible, we directly return `false`. If `dist < abs(r1 - r2)`, the smaller circle lies inside the larger one, and we sample whichever circle is smaller. Otherwise, the two circles intersect, we compute the bounding rectangle of the intersection, in which case `axis_u`, `len_u`, `axis_v`, `len_v` needs to be computed anew. Depending on the distance between the two circles, `len_v` is either the diameter of the smaller circle or the length of the common chord.
|{F13990211,height=195}|{F13990225,height=195}|{F13990274,height=195}|{F13990210,height=195}
|`dist > r1 + r2`|`dist < abs(r1 - r2)`|`dist^2 < abs(r1^2 - r2^2)`|`dist^2 > abs(r1^2 - r2^2)`
For ellipse area light, it's hard to find the smallest bounding shape of the intersection, therefore, we compute the bounding rectangle of the ellipse itself, then treat it as a rectangle light.
|{F13990386,height=195}|{F13990385,height=195}|{F13990387,height=195}
We also check the areas of the bounding rectangle of the intersection, the ellipse (disk) light, and the spread circle, then draw samples from the smallest shape of the three. For ellipse light, this also detects where one shape lies inside the other. I am not sure if we should add this measure to rectangle area light and sample from the spread circle when it has smaller area, as we seem to have a better sampling technique for rectangular (uniformly sample the solid angle). Maybe we could add [area-preserving parameterization for spherical
ellipse](https://arxiv.org/pdf/1805.09048.pdf) in the future.
**Limitation**:
At some point we switch from sampling the ellipse to sampling the rectangle, depending on the area of the both, and there seems to be a visible line (with |slope| =1) on the final rendering

the rectangle sampling method seems to have larger variance. I could not spot any bug in the implementation, and I am not sure if this happens because different sampling patterns for ellipse and rectangle are used.

Remove most of the old (pre-3.0) pose library:
- Remove The entire `editors/armature/pose_lib.c` file
- Deprecate `Object::poselib` in DNA
- Remove Operators marked as deprecated in T93405
- Remove RNA property `Object.pose_library`
- Add comment to clarify that the call `BLO_read_id_address(reader,
ob->id.lib, &ob->poselib);` handles deprecated data.
Note that this functionality has been documented as deprecated since
Blender 3.2.
What remains of the old pose library: The DNA for action markers
(`bAction::markers`) and the corresponding Python API. This will allow

rB8b7cd1ed2a17 broke this for the paint slots
rB4669178fc378 broke this for regular attributes
Name filtering in UI Lists works when:
- [one] the items to be filtered have a name property
-- see how `uilist_filter_items_default` gets the `namebuf`
- [two] custom python filter functions (`filter_items`) implement it
themselves
-- if you use `filter_items` and dont do name filtering there, the default
name filtering wont be used
So, two problems with rB8b7cd1ed2a17:
- [1] items to be listed changed from `texture_paint_images` to
`texture_paint_slots`
-- the former has name_property defined, the later lacks this
- [2] the new `ColorAttributesListBase` defined a `filter_items` function,
but did not implement name filtering
And the problem with rB4669178fc378:
- it added `filter_items` functions, but did not implement name filtering.
These are all corrected now.

This avoids need to do special trickery detecting whether the principal
point is to be changed when reloading movie clip. This also allows to
transfer the optical center from high-res footage to possibly its lower
resolution proxy without manual adjustment.
On a user level the difference is that the principal point is exposed in
the normalized coordinates: frame center has coordinate of (0, 0), left
bottom corner of a frame has coordinate of (-1, -1) and the right top
corner has coordinate of (1, 1).
Another user-visible change is that there is no more operator for setting
the principal point to center: use backspace on the center sliders will
reset values to 0 which corresponds to the center.
The code implements versioning in both directions, so it should be
possible to open file in older Blender versions without loosing
configuration.
For the Python API there are two ways to access the property:
- `tracking.camera.principal_point` which is measured in the normalized
space.
- `tracking.camera.principal_point_pixels` to access the pixel-space
principal point.
Both properties are not animatable, so there will by no conflict coming.

Always position the nodes added with the node search at the point where
the search operator was invoked by ensuring the operator context is the
main node editor region.
This was an unintended change of rBbdb57541475f, caused by the operator
now getting the cursor position in region space. So when the operator
was called from the menu, it would get the cursor position in the
region space of the menu, which lead to an offset when adding the node
since it expected the coordinates to be in the space of the node editor.
Setting the correct operator context also fixes inconsistent transform
sensitivity depending on zoom when adding nodes via the search in the
menu which has been an issue since as far back as Blender 2.79.
Also includes a small fix for the vertical offset of nodes added by the
search which varied depending on the UI scale. Same fix as in

This patch builds on the work from bdb5754147 to add node group
assets directly in the node editor add menu. Assets are added after
separators to distinguish them, but otherwise they look like any other
node. The catalog trees from all configured libraries are used to build
the menu hierarchy. Only catalogs with matching asset types are used
though.
There are a few limitations of this initial version. For now this only
supports geometry nodes. Support for other built-in node systems just
requires some refactoring of the corresponding add menu though. Lazy
loading will be added in a followup commit. For now there is a label
the first time the menu is opened.
Like the search menu integration, re-saving asset library files in 3.4
is required, if it hasn't been done already.
Implementation wise, there is a some ugly code here. A lot of that is
because the asset system isn't complete. The RNA API doesn't work well
yet, and the system isn't built to interact with multiple libraries at
once. It's also ugly because of the way we combine automatic menu
generation with builtin menus. As noted in a code comment, these two
systems could be merged completely so that the menus for builtin nodes
are also generated in the same way.

Previously, the Blender video renderer did not have support for
encoding video to AV1 (not to be confused with the container AVI).
The proposed solution is to leverage the existing FFMpeg renderer
to encode to AV1.
Note that avcodec_find_encoder(AV_CODEC_ID_AV1) usually returns
"libaom-av1" which is the "reference implementation" for AV1 encoding
(the default for FFMpeg, and is slow). "libsvtav1" is faster and
preferred so there is extra handling when fetching the AV1 codec for
encoding such that "libsvtav1" is used when possible.
This commit should only affect the options available for video
rendering, which includes the additional AV1 codec to choose from, and
setting "-crf".
Also note that the current release of FFMpeg for ArchLinux does not
support "-crf" for "libsvtav1", but the equivalent option "-qp" is
supported and used as a fallback when "libsvtav1" is used (as
mentioned here: https://trac.ffmpeg.org/wiki/Encode/AV1#SVT-AV1 ).
(Actually, both "-crf" and "-qp" is specified with the same value in
the code. When a release of FFMpeg obtains support for "-crf" for
"libsvtav1" is released, the code shouldn't be needed to change.)
The usage of the AV1 codec should be very similar to the usage of the
H264 codec, but is limited to the "mp4" and "mkv" containers.
This patch pertains to the "VFX & Video" module, as its main purpose
is to supplement the Video Sequencer tool with the additional AV1
codec for encoded video output.
