Only use the term len & maxlen when they represent the length & maximum
length of a string. Instead of the available bytes to use.
Also include the data they're referencing as a suffix, otherwise it's
not always clear what the length is in reference to.
Flickering observed when snapping to edge or face with axis constraint.
It was probably introduced in 4eda60c2d8
The snapping code has a timer, so `t->tsnap.snapElem` isn't always set.
So avoid changing the value of `t->tsnap.snapElem`.
For derived mesh triangulation information, currently the three face
corner indices are stored in the same struct as index of the mesh
polygon the triangle is part of. While those pieces of information are
often used together, they often aren't, and combining them prevents
the indices from being used with generic utilities. It also means that
1/3 more memory has to be written when recalculating the triangulation
after deforming the mesh, and that the entire triangle data has to be
read when only the polygon indices are needed.
This commit splits the polygon index into a separate cache on `Mesh`.
The triangulation data isn't saved to files, so this doesn't affect
.blend files at all.
In a simple test deforming a mesh with geometry nodes, the time used
to recalculate the triangulation reduced from 2.0 ms to 1.6 ms,
increasing overall FPS from 14.6 to 15.

cc623ee7b0 did not consider some implications such as the habit of
users initiating transform operations just to change the size of the
Proportional Edit.
Therefore, partially revert the cc623ee7b0.
Remove micro optimization that seeks to reuse the active center
alculation.
This operation is lightweight and reusing its result only adds an
unnecessary dependency.
The issue happens because the algorithm used to calculate the center of
the selection first needs to create a TransData array. In this array,
the code calculates the "mirrored" elements which can be quite slow in
dense meshes.
The solution is replace this slow algorithm used for calculating the pivot
point with the fast algorithm used to calculate the position of transform
gizmos.

Animation: Adds a new "Parent Space" Orientation option for the Transformation Gizmo.
---
For child targets (objects, bones, etc) being able to transform in parent space is a desired feature (especially when it comes to rigging / animation).
For objects:
* with a parent, the gizmo orients to it's parents orientation
* without a parent, the gizmo orients to Global space
For Armatures:
* Child bone shows parent's space regardless if "Local Location" is set for parent bone
* For root bone **without** "Local Location" set, use the armature objects space.
* For root bone **with** "Local Location" set, use local bone space.
---
No new transformation orientation code needs to be written, we can achieve the desired results be using the existing `transform_orientations_create_from_axis`, `ED_getTransformOrientationMatrix`, and `unit_m3` methods. To do this, we check to see if the bone has a parent, if so, we use the bones pose matrix (`pose_mat`). This is done similarly for objects using the parent's object matrix (`object_to_world`).

Add the ability to retrieve implicit sharing info directly from the
C++ attribute API, which simplifies memory usage and performance
optimizations making use of it. This commit uses the additions to
the API to avoid copies in a few places:
- The "rest_position" attribute in the mesh modifier stack
- Instance on Points node
- Instances to points node
- Mesh to points node
- Points to vertices node
Many files are affected because in order to include the new information
in the API's returned data, I had to switch a bunch of types from
`VArray` to `AttributeReader`. This generally makes sense anyway, since
it allows retrieving the domain, which wasn't possible before in some
cases. I overloaded the `*` deference operator for some syntactic sugar
to avoid the (very ugly) `.varray` that would be necessary otherwise.

Implements #95966, as the final step of #95965.
This commit changes the storage of mesh edge vertex indices from the
`MEdge` type to the generic `int2` attribute type. This follows the
general design for geometry and the attribute system, where the data
storage type and the usage semantics are separated.
The main benefit of the change is reduced memory usage-- the
requirements of storing mesh edges is reduced by 1/3. For example,
this saves 8MB on a 1 million vertex grid. This also gives performance
benefits to any memory-bound mesh processing algorithm that uses edges.
Another benefit is that all of the edge's vertex indices are
contiguous. In a few cases, it's helpful to process all of them as
`Span<int>` rather than `Span<int2>`. Similarly, the type is more
likely to match a generic format used by a library, or code that
shouldn't know about specific Blender `Mesh` types.
Various Notes:
- The `.edge_verts` name is used to reflect a mapping between domains,
similar to `.corner_verts`, etc. The period means that it the data
shouldn't change arbitrarily by the user or procedural operations.
- `edge[0]` is now used instead of `edge.v1`
- Signed integers are used instead of unsigned to reduce the mixing
of signed-ness, which can be error prone.
- All of the previously used core mesh data types (`MVert`, `MEdge`,
`MLoop`, `MPoly` are now deprecated. Only generic types are used).
- The `vec2i` DNA type is used in the few C files where necessary.

Check the specific case of `OP_IS_REPEAT_LAST` and recalculate
the orientation.
To that, pass the `OP_IS_REPEAT` and `OP_IS_REPEAT_LAST` flags as
inheritance to macro operators.
Implements #95967.
Currently the `MPoly` struct is 12 bytes, and stores the index of a
face's first corner and the number of corners/verts/edges. Polygons
and corners are always created in order by Blender, meaning each
face's corners will be after the previous face's corners. We can take
advantage of this fact and eliminate the redundancy in mesh face
storage by only storing a single integer corner offset for each face.
The size of the face is then encoded by the offset of the next face.
The size of a single integer is 4 bytes, so this reduces memory
usage by 3 times.
The same method is used for `CurvesGeometry`, so Blender already has
an abstraction to simplify using these offsets called `OffsetIndices`.
This class is used to easily retrieve a range of corner indices for
each face. This also gives the opportunity for sharing some logic with
curves.
Another benefit of the change is that the offsets and sizes stored in
`MPoly` can no longer disagree with each other. Storing faces in the
order of their corners can simplify some code too.
Face/polygon variables now use the `IndexRange` type, which comes with
quite a few utilities that can simplify code.
Some:
- The offset integer array has to be one longer than the face count to
avoid a branch for every face, which means the data is no longer part
of the mesh's `CustomData`.
- We lose the ability to "reference" an original mesh's offset array
until more reusable CoW from #104478 is committed. That will be added
in a separate commit.
- Since they aren't part of `CustomData`, poly offsets often have to be
copied manually.
- To simplify using `OffsetIndices` in many places, some functions and
structs in headers were moved to only compile in C++.
- All meshes created by Blender use the same order for faces and face
corners, but just in case, meshes with mismatched order are fixed by
versioning code.
- `MeshPolygon.totloop` is no longer editable in RNA. This API break is
necessary here unfortunately. It should be worth it in 3.6, since
that's the best way to allow loading meshes from 4.0, which is
important for an LTS version.

Face Nearest only works with individual projection, so always set the
`SCE_SNAP_PROJECT` flag in this case.
Also gray out the `Project Individual Elements` option in the UI if
`Face Nearest` is enabled.
And change the description to indicate that `Project Individual Elements`
is always enabled with the `Face Nearest` option.
(I feel a better design for this option needs to be considered).
The fix for #105363 (6d3ce8273a) made the transform system respect
(Frame) nodes `offsetx`/`offsety`.
Now Node Editors run the transform system even if the mouse is still (due to edge panning -- unnecessarily, see PR #106301 for fixing this). And due to the way `frame_node_prepare_for_draw` recalculates these offsets (based on
on updated positions and `node.runtime->totr` [which in turn gets rounded in `node_update_basis` -- so subpixel precision is lost there, see [1]]), this can lead to slight imprecisions/noise/jitter during transform (if we use float offsets, see the PR for more info).
So to counter this, use rounded offsets now [which will keep the whole circle stable].
NOTE: PR #106301 would fix this already for having the cursor still, but this patch still improves slight jitter when moving, so will commit separately.

The goal is to solve confusion of the "All rights reserved" for licensing
code under an open-source license.
The phrase "All rights reserved" comes from a historical convention that
required this phrase for the copyright protection to apply. This convention
is no longer relevant.
However, even though the phrase has no meaning in establishing the copyright
it has not lost meaning in terms of licensing.
This change makes it so code under the Blender Foundation copyright does
not use "all rights reserved". This is also how the GPL license itself
states how to apply it to the source code:
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software ...
This change does not change copyright notice in cases when the copyright
is dual (BF and an author), or just an author of the code. It also does
mot change copyright which is inherited from NaN Holding BV as it needs
some further investigation about what is the proper way to handle it.
"Rotate Normals" is a changeable operation like any other and does not
need to be hardcoded.
An advantage of exposing this modal is that the shortcut key now
appears in the header when rotating an edited mesh.
Avoid calling `restoreTransObjects`, `resetTransModal`,
`resetTransRestrictions` and `initSnapping` for each change.
Also bring `applyMouseInput` close to the rest of the code.
Regression introduced at 19b63b932d
The crash happened in `gizmogroup_xform_find` because
`t->region->gizmo_map` was `nullptr`.
The `T_NO_GIZMO` flag was supposed to prevent the
`gizmogroup_xform_find` function from being called, but it was being
removed with `t->flag = t->flag & ~T_PROP_EDIT_ALL;`.
This is because 19b63b932d missed updating the maximum enum value in
`ENUM_OPERATORS`.
The fix is simply to set the correct maximum value in `ENUM_OPERATORS`.
But for more safety, `gizmogroup_xform_find` now returns early when the
region does not have `gizmo_map`.

No functional changes.
The code previously contained redundant and complex checks for
different snapping scenarios, which involved combinations of multiple
snapping flags and modes on each mouse interaction. This resulted in
unnecessary code duplication and overhead.
To address this issue, the code has been simplified and micro-optimized
by moving these checks to the initialization of the snapping parameters.
This results in a more streamlined and efficient codebase.
The members `align`, `project`, `peel` and `use_backface_culling`
already have a corresponding value in `TransSnap::flag`.
Keeping values that represent the same thing is error prone.
Implements #102359.
Split the `MLoop` struct into two separate integer arrays called
`corner_verts` and `corner_edges`, referring to the vertex each corner
is attached to and the next edge around the face at each corner. These
arrays can be sliced to give access to the edges or vertices in a face.
Then they are often referred to as "poly_verts" or "poly_edges".
The main benefits are halving the necessary memory bandwidth when only
one array is used and simplifications from using regular integer indices
instead of a special-purpose struct.
The commit also starts a renaming from "loop" to "corner" in mesh code.
Like the other mesh struct of array refactors, forward compatibility is
kept by writing files with the older format. This will be done until 4.0
to ease the transition process.
Looking at a small portion of the patch should give a good impression
for the rest of the changes. I tried to make the changes as small as
possible so it's easy to tell the correctness from the diff. Though I
found Blender developers have been very inventive over the last decade
when finding different ways to loop over the corners in a face.
For performance, nearly every piece of code that deals with `Mesh` is
slightly impacted. Any algorithm that is memory bottle-necked should
see an improvement. For example, here is a comparison of interpolating
a vertex float attribute to face corners (Ryzen 3700x):
**Before** (Average: 3.7 ms, Min: 3.4 ms)
```
threading::parallel_for(loops.index_range(), 4096, [&](IndexRange range) {
for (const int64_t i : range) {
dst[i] = src[loops[i].v];
}
});
```
**After** (Average: 2.9 ms, Min: 2.6 ms)
```
array_utils::gather(src, corner_verts, dst);
```
That's an improvement of 28% to the average timings, and it's also a
simplification, since an index-based routine can be used instead.
For more examples using the new arrays, see the design task.

When multiple nodes (Frame nodes included in the selection) are scaled/
rotated, the TransData location and center can get "wrong" due to the
fact that Frame nodes dont only use `locx`/`locy` for their
representation while drawing, but also `offsetx`/`offsety`.
So in order to use the "real" top-left corner in the transform system,
we have to respect `offsetx`/`offsety` when creating/flushing transform
data.
In addition to the file in the report, this patch was also tested to work
well with nested Frame nodes.
