From Rob Blair's PR https://projects.blender.org/blender/blender/pulls/126309 .
In the code that clamps the bevel amount, the existing code could get
a denominator of 0 (from a tangent of a certain angle).
This code uses a different calculation (diagram in the PR) that clamps
when the projections of four specific edges onto another edge consumes
the whole length of that edge.
init_gaussian_blur_effect was allocating memory for sizeof(WipeVars)
instead of sizeof(GaussianBlurVars). Not a problem today since WipeVars
is slightly larger, but this is an accident waiting to happen.
Mistake in 437cb33a73.
Found while investigating #129504. Personally I don't notice
a change in behavior, but the original code, as convoluted as it
was/is, clearly tried to iterate over neighbors of neighbors rather
than iterating over neighbors twice.

For cases where a small fraction of a PBVH node is processed,
missing skipping of vertices outside of the brush radius causes
a noticeable regression. Typically we tried to avoid this sort of
filtering because it should be redundant with lowering the BVH
node size and it interferes with some other code simplicity goals.
But adding factor filtering back is a very small change.

Prior to this commit, there was an attempt to remove extra data stored
at the Sculpt Undo `Node` level, specifically an extra position array
used when a deform modifier was in the stack.
The prior commit attempted to perform the undo step by calculating a
translation between the current positions and the previous unode
position and using that as the input to the deformation process.
However, this resulted in the undo not being completely applied to the
mesh and the data remaining in a weird state.
To fix this, this commit reintroduces some previously removed functions
and constructs to perform this restore step by swapping data if
necessary. We choose to not simply revert the change that applied this
as we want to eventually reinvestigate this path, but for the imminent
4.3 release, it makes more sense to restore previous behavior.

The topology island cache needs to be freed when changing multires
levels so that it can be recalculated and be valid for a given level. To
fix this, this commit adds the `invalidate` call to the
`BKE_sculptsession_free_pbvh` method, which consolidates similar
lifecycle behavior.

`select_handle` operator did return passthrough when retiming key was
selected. This was incorrect behavior. To prevent translating retiming
keys, retiming selection must be cleared as well.

Prior to this commit, the brush action was determined on a step by step
basis by peeking at the `StrokeCache` `bstrength` property and
determining which brush to use based on if the value was negative or
not. The sign of this value, however, was not static across the
entirety of a brush stroke, as it is calculated from three separate
fields, one of which could vary over the course of a stroke when using a
tablet, the `pen_flip` property.
To fix this issue, this commit ensures the `pen_flip` field is only
updated at the beginning of the stroke and also adds a new boolean to
store the initial direction of the stroke to reduce further ambiguity
when comparing the sign of the brush strength.

With the introduction of brush assets, there are now two reasons that
motivate turning this setting on by default.
* More paint brushes - Previously, there was a single paint brush in
Sculpt mode, this made the setting for general usage less needed when
compared to the 10 brushes that are now included in the essentials
pack
* Brush settings are lost on reload - Unless the changes to a brush are
saved to the asset as a default, the color for a brush is now no
longer persisted between Blender sessions. It makes little sense to
save a specific color for a specific brush on the asset level unless
it is needed for the brush functionality.
This commit ensures that the appropriate Scene flag is set for the
unified color and defines the default primary and secondary colors as
000000 and FFFFFF, respectively.

So far asset browsers always sorted assets by name, which resulted in
barely related assets being placed together, and related assets being
scattered. This can make navigating assets tedious, and introduces a lot
of visual noise because of scattered preview image styles.
Related assets are typically put into common asset catalogs, and related
catalogs are typically organized close to each other in the catalog
hierarchy. This makes catalogs a better characteristic to sort by,
solving the mentioned issues.
For asset shelves sorting by catalogs was introduced in 471378c666. This
PR exposes this feature to the asset browser, by introducing a new
option to sort either by name or by catalog. The new default is sorting
by catalog. Within a single catalog, assets are still sorted alphabetically.

While copying this used to be very cheap, this will soon be less
trivial.
Note that there are many more places where this type of cleanup will be
needed.
Introduced by 5fff95f519.
The issue was that the `edit_points_vflag` buffer is of size `total_points_num`
which is based on the number of control points not evaluated positions.
The fix is to use `points_by_curve` instead of `points_by_curve_eval`
to get the right start and end indices.

The Factor input of the compositor RGB Curves node has a wrong minimum
range of -1, while it should be 0. This is clamped during execution, so
it has no effect, but it is good to align UI with code.
