Probably to prevent the radius of a point from being stuck at zero,
the `Shrink/Fatten` curve operator sets a minimum value of `0.001`
for all points being transformed.
This is an inconvenience as these points may have been purposely set
to zero on the panel.
And it also doesn't follow the convention seen in other operators
(which keep the value zero).
So remove this limitation.
Add a 'Delete Confirmation' operator property to the 'Delete Marker'
operator. This determines whether the user is asked to confirm the
deletion or not.
Defaults so that only {key X} ({key Backspace} for industry compatible
keymap) prompts for deletion, whereas {key Del} does not show the
confirmation popup.
This also makes the default keymap for marker deletion consistent with
the common delete operators (such as objects and keyframes).

In UV edge mode, box and lasso selections allow edge selections only
when the entire edge is contained within the selection area. This
doesn't consider any edges that partially overlap with the selection
area.
This is now fixed by adding a second pass, similar to how these
operators work for edit-mesh selections. Now if both operators are
unable to find any edges contained within the selection area, then
they will perform a second pass which checks for edges that partially
intersect with the selection area.
Now edge selection in the UV editor matches edit-mesh edge-selection
when drawing wire-frame.

A mesh wrapper might be being accessed for read-only from one thread
while another thread converts the wrapper type to something else.
The proposes solution is to defer assignment of the mesh wrapper
type until the wrapper is fully converted. The good thing about this
approach is that it does not introduce extra synchronization (and,
potentially, evaluation pipeline stalls). The downside is that it
might not work with all possible wrapper types in the future. If a
wrapper type which does not clear data separation is ever added in
the future we will re-consider the threading safety then.
Unfortunately, some changes outside of the mesh wrapper file are
to be made to allow "incremental" construction of the mesh prior
changing its wrapper type.
Unfortunately, there is no simplified file which demonstrates the
issue. It was investigated using Heist production file checked at
the revision 1228: `pro/lib/char/einar/einar.shading.blend`. The
repro case is simple: tab into edit mode, possibly few times.
The gist is that there several surface deform and shrinkwrap
modifiers which uses the same target. While one of them is building
BVH tree (which changes wrapper type) the other one accesses it for
read-only via `BKE_mesh_wrapper_vert_coords_copy_with_mat4()`.

Some ID types did not have a filter value, even though they would be
used in remapping code, leading to missing remappings. In that specific
case, shape keys would actually never be properly remapped.
Reproducible in r1230 of
`Heist/pro/animation_test/einar/einar_new_expression_shapes2.blend`,
When dealing with 'embedded' IDs (and the like, e.g. shape keys),
liboverride code could fail in case the reference linked data (e.g. a
mesh) would not have a shapekey anymore, while the override mesh would
still have one.

The GPU_SHADER_BUILDER is a buildtime tool for developers
to pre-validate GLSL (and in the overseen future pre-compile to
SpirV). We don't see that this needs to become a required

is more descriptive name.
Note there is a bug in BKE_object_is_visible_in_viewport, it
returns false when the object is in local mode.
The transform operator poll should do a similar test. That
would allow us to move the test from sculpt_brush_strok_invoke
to SCULPT_mode_poll (at the moment we cannot do this due to
the brush operator falling through to the translate keymap
item in global view3d keymap).

The face merging code in exact boolean made an assumption that
the tesselated original face was manifold except at the boundaries.
This should be true but sometimes (e.g., if the input faces have
self-intersection, as happens in the example), it is not.
This commit makes face merging tolerant of such a situation.
It might leave some stray edges from triangulation, but it should
only happen if the input is malformed.
Note: the input may be malformed if there were previous booleans
in the stack, since snapping the exact result to float coordinates
is not guaranteed to leave the mesh without defects.
The importer code was written under incorrect assumption that vertex
data (v, vn, vt commands etc.) are grouped by object, i.e. follow the
o command, and that each object has its own vertex data commands. This
is not the case -- all the vertex data in the whole OBJ file is
"global", with no relation to any objects/groups; it's just that the
faces belong to the object, and then they pull in any vertices they
like.
This patch fixes this incorrect assumption in the importer:
- Vertex data is now properly global; no need to track some sort of
"offsets" per object like it was doing before.
- For each object, face definitions track the minimum & maximum vertex
indices referenced by the object, and then all that vertex range is
created in the final Blender object. Note: it might be (unusual, but
possible) that an object does not reference a sequential range of
vertices, e.g. just a single face with vertex indices 1, 10, 100 --
the resulting Blender mesh will have all the 100 vertices (some
"loose" without belonging to a face). It should be possible to track
the used vertices exactly (e.g. with a vector set), but I haven't
done that for performance reasons.

Address the issue by re-working line continuation handling: stop
trying to parse sequences like "backslash, newline" (which is the
bug: it should also handle "backslash, possible whitespace, newline")
during parsing. Instead, fixup line continuations after reading chunks
of input file data - turn backslash and the following newline into
spaces. The rest of parsing code does not have to be aware of them
at all then.
Makes the file attached to T99536 load correctly now. Also will extend
one of the test files in subversion tests repo to contain backslashes
followed by newlines.

In some cases it is mandatory to be able to hide parts of the mesh
in order to paint certain areas. The Mask modifier doesn't work in
weight paint, and edit mode hiding requires using selection, which
is not always convenient.
This makes the weight and vertex paint modes always respect edit mode
hiding like sculpt mode. The change in behavior affects drawing and
building paint PBVH. Thus it affects brushes, but not menu operators
like Smooth or Normalize.
In addition, this makes the Alt-H shortcut available even without
any selection enabled, and implements Hide for vertex selection.

Currently, there are two attribute API. The first, defined in `BKE_attribute.h` is
accessible from RNA and C code. The second is implemented with `GeometryComponent`
and is only accessible in C++ code. The second is widely used, but only being
accessible through the `GeometrySet` API makes it awkward to use, and even impossible
for types that don't correspond directly to a geometry component like `CurvesGeometry`.
This patch adds a new attribute API, designed to replace the `GeometryComponent`
attribute API now, and to eventually replace or be the basis of the other one.
The basic idea is that there is an `AttributeAccessor` class that allows code to
interact with a set of attributes owned by some geometry. The accessor itself has
no ownership. `AttributeAccessor` is a simple type that can be passed around by
value. That makes it easy to return it from functions and to store it in containers.
For const-correctness, there is also a `MutableAttributeAccessor` that allows
changing individual and can add or remove attributes.
Currently, `AttributeAccessor` is composed of two pointers. The first is a pointer
to the owner of the attribute data. The second is a pointer to a struct with
function pointers, that is similar to a virtual function table. The functions
know how to access attributes on the owner.
The actual attribute access for geometries is still implemented with the `AttributeProvider`
pattern, which makes it easy to support different sources of attributes on a
geometry and simplifies dealing with built-in attributes.
There are different ways to get an attribute accessor for a geometry:
* `GeometryComponent.attributes()`
* `CurvesGeometry.attributes()`
* `bke::mesh_attributes(const Mesh &)`
* `bke::pointcloud_attributes(const PointCloud &)`
All of these also have a `_for_write` variant that returns a `MutabelAttributeAccessor`.

Curves that are attached to a surface can now follow the surface when
it is modified using shape keys or modifiers (but not when the original
surface is deformed in edit or sculpt mode).
The surface is allowed to be changed in any way that keeps uv maps
intact. So deformation is allowed, but also some topology changes like
subdivision.
The following features are added:
* A new `Deform Curves on Surface` node, which deforms curves with
attachment information based on the surface object and uv map set
in the properties panel.
* A new `Add Rest Position` checkbox in the shape keys panel. When checked,
a new `rest_position` vector attribute is added to the mesh before shape
keys and modifiers are applied. This is necessary to support proper
deformation of the curves, but can also be used for other purposes.
* The `Add > Curve > Empty Hair` operator now sets up a simple geometry
nodes setup that deforms the hair. It also makes sure that the rest
position attribute is added to the surface.
* A new `Object (Attach Curves to Surface)` operator in the `Set Parent To`
(ctrl+P) menu, which attaches existing curves to the surface and sets the
surface object as parent.
Limitations:
* Sculpting the procedurally deformed curves will be implemented separately.
* The `Deform Curves on Surface` node is not generic and can only be used
for one specific purpose currently. We plan to generalize this more in the
future by adding support by exposing more inputs and/or by turning it into
a node group.
