The simple subdivision as a type only causes issues like no-continuous
normals across edges, inability to reliably switch the type and things
like this.
The new subdivision operators supports wider variety of how to add
details to the model, which are more powerful than a single one-time
decision on the subdivision type.
The versioning code is adjusting topology converter to specify all
edges as infinitely sharp. The reason for this (instead of using
settings.is_simple) is because in a longer term the simple subdivision
will be removed from Subsurf modifier as well, and will be replaced
with more efficient bmesh-based modifier.
This is finished up version of D8436.

Improved user experience by using viewport focal length
to calculate the new camera distance.
Also resizing the border to the same aspect ratio as
the window will help not zooming in more than expected.

For Customdata layer copying, interpolation with the mixfactor is only
done for certain mix modes, now set the UI inactive if the mixfactor is
not in use.
Namely, the modes are the "Above / Below Threshold" which are only used
for flags, colors and normals and mixing is not supported in these cases.
Spotted while looking into T81914.

Draw the handles for the active keyframe only when the interpolation type
is set to Bézier. This now matches the behaviour of handles of regular
(non-active) keyframes.
Activate an FCurve only on selecting, and not on deselecting a keyframe
or a handle.

This patch improves the single core performance of the lattice deform.
1. Prefetching deform vert during initialization. This data is constant for
each innerloop. This reduces the complexity of the inner loop what makes
more CPU resources free for other optimizations.
2. Prefetching the Lattice instance. It was constant. Although performance
wise this isn't noticeable it is always good to free some space in the
branch prediction tables.
3. Remove branching in all loops by not exiting when the effect of the loop
isn't there. The checks in the inner loops detected if this loop didn't
have any effect on the final result and then continue to the next loop.
This made the branch prediction unpredictable and a lot of mis
predictions were done. For smaller inner loops it is always better
to remove unpredictable if statements by using branchless code patterns.
4. Use SSE2 instruction when available.
This gives 50% performance increase measured on a
Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz with GCC 9.3.
Also check other compilers.

This looks like a optimizer bug where it makes wrong assumptions.
The code inside lib_id_delete:264 on rBafd13710b897cc1c11b
`for (id = last_remapped_id->next; id; id = id->next) {..}`
is not executed in release/relwithdebinfo builds.
This can be "fixed" by several ways:
- Adding a line that prints the `last_remapped_id->name` right before
the said for-loop starts.
- Turning off optimization for the whole function `id_delete`:
`#pragma clang optimize off/on` Ray Molenkamp
- Marking `last_remapped_id` volatile. Julian Eisel
- Marking `tagged_deleted_ids` volatile. But it adds a warning when
calling `BLI_addtail`: discards volatile qualifier. Discovered by
accident.

The plane deformation falloff was introduced in the first version of the
cloth brush, but due to the lack of all the new features and fixes in the
solver it was causing a lot of artifacts for deformation brushes. In
order to avoid that, the cloth brush was always using radial falloff for
the grab brush.
Now the plane falloff is properly implemented using the deformation
constraints.

This adds a tool property for sculpt line gesture tools (line and
project) to limits its effect to the segment of the gesture instead of
using the infinite line to bisect the mesh in two parts.
To achieve that, the line gesture now has two extra side planes that can
be enabled/disabled for getting the nodes from the PBVH and to test the
vertices.

This adds an operation mode to the Face Set Edit tool which deletes the
geometry of a Face Set by clicking on it.
The operator also checks for the mesh having a single Face Set to avoid
deleting the entire object by accident.
This is also disabled for Multires to avoid modifying the limit surface
without control (it is not an important limitation as base meshes for
multires are usually final, but maybe it can be supported in the future).
