This patch uses the recorded drawing speed to rebuild the strokes. This results in a way more
natural feel of the animation.
Here's a short summary of existing data used:
- gps->points->time: This is a timestamp in seconds of when the point was created
since the creation of the stroke. It's quite often 0 (I added a sanitization routine).
- gpf->inittime: This is a timestamp in seconds when a stroke was drawn measured
since some unknown point in time. I only ever use the difference between two strokes,
so the absolute value is not relevant.

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 slider component can now be told to not use CTRL for toggling stepped
10% increments. This is useful when the operator that uses the slider needs
that modifier key for its own purposes.
Due an internal scale of the brush size done by grease pencil
draw tool (this scale factor cannot be removed), the size of the
radial control is not equal to the actual stroke thickness and
this makes the radial size displayed useless.
This patch adds a new property that allows to pass the
path of the tool path and this value is used to apply
the correct scale to the radial size.

Use the same `".selection"` attribute for both curve and point domains,
instead of a different name for each. The attribute can now have
either boolean or float type. Some tools create boolean selections.
Other tools create float selections. Some tools "upgrade" the attribute
from boolean to float.
Edit mode tools that create selections from scratch can create boolean
selections, but edit mode should generally be able to handle both
selection types. Sculpt mode should be able to read boolean selections,
but can also and write float values between zero and one.
Theoretically we could just always use floats to store selections,
but the type-agnosticism doesn't cost too much complexity given the
existing APIs for dealing with it, and being able to use booleans is
clearer in edit mode, and may allow future optimizations like more
efficient ways to store boolean attributes.
The attribute API is usually used directly for accessing the selection
attribute. We rely on implicit type conversion and domain interpolation
to simplify the rest of the code.

Add a field `is_bidirectional` to sliders (`tSlider`). By defafult this
is `false`; when set to `true` the slider allows negative values.
The allowed ranges are now:
- No overshoot, no bidirectional: `[0, 1]`
- No overshoot, bidirectional: `[-1, 1]`
- Overshoot, no bidirectional: `[0, infinity)`
- Overshoot, bidirectional: `(-infinity, infinity)`
This will be used for the pose library blending operator, where sliding
to the right (postitive) blends as normal, and sliding to the left
(negative) flips the pose before blending.
Move `pose_backup.cc` from `editors/armature` to `blenkernel`. This is
in preparation of an upcoming change where the pose backup is going to be
owned by the `Object`. This will need to be automatically cleared when the
object is freed, which means that `blenkernel` needs the corresponding
logic.
Technically only the freeing code could be moved, but I felt it made more
sense to keep the related code together.
No functional changes.
- Move from blenkernel to the node editor, the only place it was used
- Use two vectors instead of ListBase
- Remove define for validating the clipboard, which shouldn't be skipped
- Comment formatting, other small cleanups to whitespace

Recently a new geometry node for splitting edges was added in D16399.
However, there was already a similar implementation in mesh.cc that was
mainly used to fake auto smooth support in Cycles by splitting sharp
edges and edges around sharp faces.
While there are still possibilities for optimization in the new code,
the implementation is safer and simpler, multi-threaded, and aligns
better with development plans for caching topology on Mesh and other
recent developments with attributes.
This patch removes the old code and moves the node implementation to
the geometry module so it can be used in editors and RNA. The "free
loop normals" argument is deprecated now, since it was only an internal
optimization exposed for Cycles.
The new mesh `editors` function creates an `IndexMask` of edges to
split by reusing some of the code from the corner normal calculation.
This change will help to simplify the changes in D16530 and T102858.

Migrate (some) of the UDIM offset calculation from inside one
of the packing engines (where it's consumed) to the packing
operator (where it's produced).
This change (and others) will help simplify the future migration
of the packing engine inside editors/uvedit/uvedit_islands.cc
to the Geometry module, so it can eventually replace the other
packing engine in geometry/intern/uv_parametrizer.cc
This patch adds an integer identifier to nodes that doesn't change when
the node name changes. This identifier can be used by different systems
to reference a node. This may be important to store caches and simulation
states per node, because otherwise those would always be invalidated
when a node name changes.
Additionally, this kind of identifier could make some things more efficient,
because with it an integer is enough to identify a node and one does not
have to store the node name.
I observed a 10% improvement in evaluation time in a file with an extreme
number of simple math nodes, due to reduced logging overhead-- from
0.226s to 0.205s.

When entering paint modes the paint pivot was cleared,
which broken rotate around pivot. Fixed for all paint modes.
PBVH modes set the pivot to the PBVH bounding box
while texture paint uses the evaluated mesh bounding box.
As part of T95966, this patch moves loose edge information out of the
flag on each edge and into a new lazily calculated cache in mesh
runtime data. The number of loose edges is also cached, so further
processing can be skipped completely when there are no loose edges.
Previously the `ME_LOOSEEDGE` flag was updated on a "best effort"
basis. In order to be sure that it was correct, you had to be sure
to call `BKE_mesh_calc_edges_loose` first. Now the loose edge tag
is always correct. It also doesn't have to be calculated eagerly
in various places like the screw modifier where the complexity
wasn't worth the theoretical performance benefit.
The patch also adds a function to eagerly set the number of loose
edges to zero to avoid building the cache. This is used by various
primitive nodes, with the goal of improving drawing performance.
This results in a few ms shaved off extracting draw data for some
large meshes in my tests.
In the Python API, `MeshEdge.is_loose` is no longer editable.
No built-in addons set the value anyway. The upside is that
addons can be sure the data is correct based on the mesh.
**Tests**
There is one test failure in the Python OBJ exporter: `export_obj_cube`
that happens because of existing incorrect versioning. Opening the
file in master, all the edges were set to "loose", which is fixed
by this patch.

Introduces a new `AssetRepresentation` type, as a runtime only container
to hold asset information. It is supposed to become _the_ main way to
represent and refer to assets in the asset system, see T87235. It can
store things like the asset name, asset traits, preview and other asset
metadata.
Technical documentation:
https://wiki.blender.org/wiki/Source/Architecture/Asset_System/Back_End#Asset_Representation.
By introducing a proper asset representation type, we do an important
step away from the previous, non-optimal representation of assets as
files in the file browser backend, and towards the asset system as
backend. It should replace the temporary & hacky `AssetHandle` design in
the near future. Note that the loading of asset data still happens
through the file browser backend, check the linked to Wiki page for more
information on that.
As a side-effect, asset metadata isn't stored in file browser file
entries when browsing with link/append anymore. Don't think this was
ever used, but scripts may have accessed this. Can be brought back if
there's a need for it.
In anticipation of UV Copy+Paste, we need fast access to indices
of unique UvElements. Can also be used to improve performance and
simplify code for UV Sculpt tools and UV Stitch.
No user visible changes expected.

When changing the texture paint slot index or activating a Texture Node, the texture displayed in the Image Editor changes accordingly.
This patch syncs the Image Editor when a new texture paint slot was added, which currently is not the case.
Also deduplicates some code.
Use the node topology cache and avoid modifying the node tree
in a non-threadsafe way to improve the predictability of using
the helper function. Replaces the implementation from
e0d4047136.
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.

Adds the possibility of having a little number on top of icons.
At the moment this is used for:
* Outliner
* Node Editor bread-crumb
* Node Group node header
For the outliner there is almost no functional change. It is mostly a refactor
to handle the indicators as part of the icon shader instead of the outliner
draw code. (note that this was already recently changed in a5d3b648e3).
The difference is that now we use rounded border rectangle instead of
circles, and we can go up to 999 elements.
So for the outliner this shows the number of collapsed elements of a
certain type (e.g., mesh objects inside a collapsed collection).
For the node editors is being used to show the use count for the data-block.
This is important for the node editor, so users know whether the node-group
they are editing (or are about to edit) is used elsewhere. This is
particularly important when the Node Options are hidden, which is the
default for node groups appended from the asset libraries.

Note: This can be easily enabled for ID templates which can then be part
of T84669. It just need to call UI_but_icon_indicator_number_set in the
function template_add_button_search_menu.

A refactor of the margin calculation of UV packing, in anticipation
of multiple packing methods soon becoming available.
Three margin scaling methods are now available:
* "Add", Simple method, just add the margin. [0]
(The default margin scale from Blender 2.8 and earlier.)
* "Scaled", Use scale of existing UVs to multiply margin.
(The default from Blender 3.3+)
* "Fraction", a new (slow) method to precisely specify
a fraction of the UV unit square for margin. [1]
The "fraction" code path implements a novel combined search / secant
root finding method which exploits domain knowledge to accelerate
convergence while remaining robust against bad input.
