rBb70bbfadfece allowed scaling of zero-radius points, but as it behaves
differently from other radius, it may not be suitable for multi-point
transformation.
Kind of intentional regression on rB2d1fe736fabd.
But the solution now is (theoretically) better than adding a hard coded
threshold.
For cases with zero radius, the new radius is now the offset of the
ratio projected onto the plane of the origin point.
Error introduced in rB1edebb794b76.
In that commit it was kind of forgotten that the snap to grid is also
used in 3D views.
Also a refactoring and cleanup was applied to simplify the code.
In rBed6c8d82b804 it was wrongly assumed that the constraint functions
always apply the transformations.
But that is not the case for when axes are aligned.
The `mul_m3_v3(t->con.pmtx, out)` fallback is still required.
Part of a wider set of changes to Grid and Pixel snapping in the
UV Editor.
This change fixes snapping behavior for non-uniform grids, either
manually specified Fixed grids, or pixel grids where the underlying
image is non-square.

This commit replaces the `Mesh_Runtime` struct embedded in `Mesh`
with `blender::bke::MeshRuntime`. This has quite a few benefits:
- It's possible to use C++ types like `std::mutex`, `Array`,
`BitVector`, etc. more easily
- Meshes saved in files are slightly smaller
- Copying and writing meshes is a bit more obvious without
clearing of runtime data, etc.
The first is by far the most important. It will allows us to avoid a
bunch of manual memory management boilerplate that is error-prone and
annoying. It should also simplify future CoW improvements for runtime
data.
This patch doesn't change anything besides changing `mesh.runtime.data`
to `mesh.runtime->data`. The cleanups above will happen separately.

- Give functions and variables more descriptive names
- Use references for arguments
- Use tree topology cache to avoid iterating over all links
- Group related code together
Do not save the "use_proportional_edit" property if it is not supported.
This prevents it from being automatically disabled.
And hide "use_proportional_edit" in `SPACE_NLA`
Refactor the `recalcData_nla()` function, which takes data from the
transform system and updates NLA strips, such that the actual logic to
change the strip is moved into its own function.
This also moves some generic code (find prev/next strip) from that
function to BKE.
This is to make the code easier to adjust when different transform
operations need to perform different modifications of the strip (i.e. to
fix T101130).

Add function `SEQ_time_content_end_frame_get` to get content end frame.
New function is shorthand for
`SEQ_time_start_frame_get() + SEQ_time_strip_length_get()`.
This is the conventional way of dealing with unused arguments in C++,
since it works on all compilers.
Regex find and replace: `UNUSED\((\w+)\)` -> `/*$1*/`
Two new normal-based automasking modes.
The first mode, "brush", compares vertex normals with the initial
normal at the beginning of the brush stroke.
The second, "view", compares vertex normals with the view normal.
If "occlusion" is on then rays will be shot from each vertex to test
if it is occluded by other geometry (note: this can be very slow).\
Only geometry inside the sculpt mesh is considered.
Each mode has an associated angular limit and a falloff.

Typo in rBa8a454287a27 (created layer on edge data instead of vertex
data).
Maniphest Tasks: T101393
Differential Revision: https://developer.blender.org/D16079
Changes:
- Use the "snap_elements" property only for operators that support snapping to geometry.
- Remove unused properties:
- "use_snap_to_same_target",
- "snap_face_nearest_steps").
- Fix property with wrong name "use_snap_selectable_only" -> "use_snap_selectable"
- Fix use of dependent property flags.
- Remove redundant initialization of variables
- Simplify `poll_propety`. Only the "use_snap_project" is not hidden.
>>! In rBc484599687ba it's said:
> These options are needed for Python tools to control snapping without requiring the tool settings to be adjusted.
If that's the case, there doesn't seem to be any need to display them in the redo panel. Therefore:
- Hide snapping properties in redo panel.
Many properties have been added that can be independent of ToolSettings. Therefore:
- Save snapping properties in the operator itself. For Redo.
This is very similar to D14077. There are two differences though.
First is that vertex creases are already stored in a separate layer,
and second is that we can now completely remove use of `Mesh.cd_flag`,
since that information is now inherent to whether the layers exist.
There are two functional differences here:
* Operators are used to add and remove layers instead of a property.
* The "crease" attribute can be created and removed by geometry nodes.
The second change should make various geometry nodes slightly faster,
since the "crease" attribute was always processed before. Creases are
now interpolated generically in the CustomData API too, which should
help maintain the values across edits better.
Meshes get an `edge_creases` RNA property like the existing vertex
property, to provide more efficient access to the data in Cycles.
One test failure is expected, where different rounding between float
the old char storage means that 5 additional points are scattered in
a geometry nodes test.

When a change happens which invalidates view layers the syncing will be postponed until the first usage.
This will improve importing or adding many objects in a single operation/script.
`BKE_view_layer_need_resync_tag` is used to tag the view layer to be out of sync. Before accessing
`BKE_view_layer_active_base_get`, `BKE_view_layer_active_object_get`, `BKE_view_layer_active_collection`
or `BKE_view_layer_object_bases` the caller should call `BKE_view_layer_synced_ensure`.
Having two functions ensures that partial syncing could be added as smaller patches in the future. Tagging a
view layer out of sync could be replaced with a partial sync. Eventually the number of full resyncs could be
reduced. After all tagging has been replaced with partial syncs the ensure_sync could be phased out.
This patch has been added to discuss the details and consequences of the current approach. For clarity
the call to BKE_view_layer_ensure_sync is placed close to the getters.
In the future this could be placed in more strategical places to reduce the number of calls or improve
performance. Finding those strategical places isn't that clear. When multiple operations are grouped
in a single script you might want to always check for resync.
Some areas found that can be improved. This list isn't complete.
These areas aren't addressed by this patch as these changes would be hard to detect to the reviewer.
The idea is to add changes to these areas as a separate patch. It might be that the initial commit would reduce
performance compared to master, but will be fixed by the additional patches.
**Object duplication**
During object duplication the syncing is temporarily disabled. With this patch this isn't useful as when disabled
the view_layer is accessed to locate bases. This can be improved by first locating the source bases, then duplicate
and sync and locate the new bases. Will be solved in a separate patch for clarity reasons ({D15886}).
**Object add**
`BKE_object_add` not only adds a new object, but also selects and activates the new base. This requires the
view_layer to be resynced. Some callers reverse the selection and activation (See `get_new_constraint_target`).
We should make the selection and activation optional. This would make it possible to add multiple objects
without having to resync per object.
**Postpone Activate Base**
Setting the basact is done in many locations. They follow a rule as after an action find the base and set
the basact. Finding the base could require a resync. The idea is to store in the view_layer the object which
base will be set in the basact during the next sync, reducing the times resyncing needs to happen.
