"None", or off when hinting is "Full".

For text objects, the CharInfo mat_nr material index used to start at 1
(not at zero like for meshes or nurbs).
Code was mostly considering this (but not in all places, so material
index handling (removing/moving) could still go wrong.
As an alternative to !109746 (where it was made sure all places would
make the right assumption about mat_nr starting at 1), this PR now
changes the mat_nr to be zero-based.
This is more in line with other places handling material indices.
Versioning code is in place to properly convert old files.

For Blender 4.0 we decided to support individual icons for different
snap elements.
This was originally contributed by Erik Abrahamsson as !107054 with
some contributions by myself (Germano).
This set of icons being simple geometric symbols, that should be
familiar to CAD artists.
Note that Face and Volume share the same icon (circle). This is
deliberate since they communicate a similar functionality - are not
aimed at precision snapping the same way the vertex or perpendicular
are.
Also note that later we should also try to change the icons shown in
the snap menu to match the symbols that the artists see in the preview
window.
———
On the decision process:
The version currently in main (and rolled back here) was an initial
attempt of aggregating more information to the icons (e.g., by aligning
the icons to the target edges) while making them more suitable to
Blender. After presenting both options to (parts of the) community,
there was nothing fundamentally broken found with either option, though
options diverged over personal preference.
With that in mind, in the latest UI module meeting it was agreed to use
the original proposal then.
This final call was proposed by Dalai Felinto on his role of
commissioner (stakeholder) for the snap polishing tasks (#73993) and
designer for the related Snap Base design #66484.
———
This commit reverts commit 9c2e768f5b.
The reverted icons (referred originally as minimalistic icons) may be
proposed later as a separate theme option.
Adds a menu to choose the asset library to use to the asset shelf
catalogs selector popover. This is consistent with the asset browser.
After talking to animators and some artists, this is likely something
they would want to have, since they don't always want all their assets
and catalogs to populate the asset shelf. It's also necessary for the
pose library UI to provide the same features roughly than the old one
(in the sidebar, before the asset shelf was introduced).
Previously, it was only possible to inspect the data from the first iteration. That
applied to both, the viewer node as well as socket inspection. Now, there is a
new `Inspection Index` setting in the zone properties. It specifies which iteration
should be used by the inspection features.
In theory we could support features like counting the index from the end, but
that can be done separately as well, as it likely requires more UI.

This PR adds vertex groups to `CurvesGeometry` as well as an attribute read/write accessor.
This is also in preparation for GPv3. Since the goal is to have full compatibility with the current grease pencil features, vertex groups need to be supported.
Grease Pencil allows filtering by vertex group for modifiers.To support this, it also makes sense to have read/write access for vertex groups in the attributes API.
In the future, vertex groups should be just another custom attribute on meshes/curves/grease pencil. There are some more issues to be solved before that can happen. This step gets us a bit closer since the vertex weight data is stored in `CustomData`.

Currently retiming is quite awkward, when you need to retime multiple
strips strips in sync. It is possible to use meta strips, but this is
still not great. This is resolved by implementing selection.
General changes:
Gizmos are removed, since they are designed to operate only on active
strip and don't support selection.
Transform operator code is implemented for retiming data, which allows
more sophisticated manipulation.
Instead of drawing marker-like symbols, keyframes are drawn to
represent retiming data. Retiming handles are now called keys. To have
consistent names, DNA structures have been renamed.
Retiming data is drawn on strip as overlay.
UI changes:
Retiming tool is removed. To edit retiming data, press Ctrl + R, select
a key and move it. When retiming is edited, retiming menu and
context menu shows more relevant features, like making transitions.
Strip and retiming key selection can not be combined. It is possible to
use box select operator to select keys, if any key is selected.
Otherwise strips are selected.
Adding retiming keys is possible with I shortcut or from menu.
Retiming keys are always drawn at strip left and right boundary. These
keys do not really exist until they are selected. This is to simplify
retiming of strips that are resized. These keys are called "fake keys"
in code.
API changes:
Functions, properties and types related to retiming handles are renamed
to retiming keys:
retiming_handle_add() -> retiming_key_add()
retiming_handle_move() -> retiming_key_move()
retiming_handle_remove() -> retiming_key_remove()
retiming_handles -> retiming_keys
RetimingHandle -> RetimingKey
Retiming editing "mode" is activated by setting `Sequence.show_retiming_keys`.

Shadow Map Ray Tracing is a technique that ray cast against the shadow
depth buffer. The technique is described in "Soft Shadows by
Ray Tracing Multilayer Transparent Shadow Maps".
Note that we only implement the single layer approach since storing
multiple depth is prohibitively expensive.

Previously, it was only possible to bake all simulations at once. This is great
for simple use-cases that, but in more complex setups one can have independent
simulations that should also be baked independently. This patch allows baking
individual simulation zones.
Furthermore, each simulation zone can now also have its own bake path and
simulation frame range. By default the simulation frame range is the scene frame
range, but it can also be customized on the scene or simulation zone level. The
bake path is generated based on the modifier bake path by default, but can be
set to another absolute or relative (to the .blend file) path.
The timeline drawing has been modified as well to be able to show more information
in the case when some simulations are baked and others are not. Instead of showing
a line for every simulation, it shows a condensed view of the important information
using at most two lines:
Is something baked? Is something valid or invalid? Also see #112232.

Draw the background of the asset shelf header fully transparent, with an opaque
background with rounded corners behind sections containing buttons. This
reduces the visual space consumed by the asset shelf, and makes the header
follow a tabbed folder metaphor better. Also, this works much better with our
click-through feature, where transparent parts of regions without buttons are
passed through the region under it (we might want to consider unifying code
here a bit).
The edge to drag for region resizing respects the transparent sections.
When there is little space between sections, the sections get merged so that
there are no small gaps in the bar.
Part of #107881.

Note that the core of this is implemented in a generic way, so this can be
reused for other regions.

It was already called that way in the UI, since it's referring to a
behavior, not a type. Update the code to match that. Note that this is
a BPY compatibility breaking change for 4.0.
Currently vertices are mapped to B-Bone segments without taking the
rest pose curve into account. This is very simple and fast, but causes
poor deformations in some cases where the rest curvature is significant,
e.g. mouth corners in the new Rigify face rig.
This patch implements a new mapping mode that addresses this problem.
The general idea is to do an orthogonal projection on the curve. However,
since there is no analytical solution for bezier curves, it uses the
segment approximation:
* First, boundaries between segments are used for a binary space
partitioning search to narrow down the mapping to one segment.
* Then, a position on the segment is chosen via linear
interpolation between the BSP planes.
* Finally, to remove the sharp discontinuity at the evolute surface
a smoothing pass is applied to the chosen position by blending to
reduce the slope around the planes previously used in the BSP search.
In order to make per-vertex processing faster, a new array with the
necessary vectors converted to the pose space, as well as some
precomputed coefficients, is built.
The new mode is implemented as a per-bone option in order to ensure
backward compatibility, and also because the new mode may not be
optimal for all cases due to the difference in performance, and
complications like the smoothed but still present mapping
discontinuities around the evolute surface.

Enable visual keying of bones that are influenced by an IK constraint.
This wasn't possible before, as the visual keying system only checked
constraints on the bone itself, and not whether the bone was part of an
IK chain.
This commit introduces a new `bPoseChannel::constflag` value
`PCHAN_INFLUENCED_BY_IK` that is set whenever the pose bone is part of
an IK chain.
The `pchan->constflag` field is computed during depsgraph evaluation. If
the depsgraph is active, it is now also written back to the original
pchan, so that it can be used in the "should visual keying be used"
function.
Fixes: #76791 "Different results when keyframing visual transforms and
applying transforms manually on IK constraint". Note that visually
keying does *not* copy the visual pose to the current pose. Furthermore,
when visually keying only part of the IK chain, the result of
re-evaluating the IK constraint (for example by moving the scene forward
and then backward by one frame) may still produce a different result, as
the IK chain now has a different start orientation.
Note that commit explicitly does not cover Spline IK constraints. They
can introduce heavy shear, especially with the default settings, which
cannot be represented by keys on loc/rot/scale.
For historical reference: 876cfc837e
introduces the 'use visual keying' preference option, where Blender
automatically chooses whether or not to use visual keying. This is why
there is a function at all that determines whether to use visual keying
or not.
Rename the `bPoseChannel::flag` `PCHAN_HAS_TARGET` to `PCHAN_HAS_NO_TARGET`
as that is actually the meaning of the flag (in the majority of the code).
Since the flag was so confusingly named, there were some mixups in the
armature overlay drawing code as well, which have been fixed now too.
Add a checkbox to node group inputs to force inputs to be single values
and not accept varying fields. While this could also be done more
automatically, and it could be argued that requiring the flexibility is
helpful for users who want to use attributes, there are cases where the
field inferencing doesn't work, or the "use attribute" option is just
unhelpful. People use workarounds with primitive nodes to get the same
behavior anyway.

In preparation of https://projects.blender.org/blender/blender/pulls/112535, we need to make sure all layer tree manipulations are in functions on the `GreasePencil` struct so we can keep the `CustomData` for layers in sync with the layer tree.
This PR makes sure that all the functions that change the layer tree in any way are `protected` on the `LayerGroup` class. The `GreasePencil` struct is declared `friend` with `LayerGroup`.
We also cleanup and remove a lot of code duplication between layers and layer groups and try to write functions in a generic way for `TreeNode` (both layers and layer groups are tree nodes).

The goal is to make the search faster to use by dynamically adapting to the user.
This can be achieved using the simple but common approach of showing recently
selected items at the top. Note, that the "matching score" between the query and
each search item still has precedence when determining the order. So the last used
item is only at the top, if there is no other search item that matches the query better.
Besides making the search generally faster to use, my hope is that this can also
reduce the need for manually weighting search items in some places. This is
because while the ordering might not be perfect the first time, it will always be
once the user selected the element that should be at the top once.
This patch includes:
* Support for taking recent searches into account in string searching.
* Keep track of a global list of recent searches.
* Store recent searches on disk similar to recently opened files.
* A new setting in the user preferences that allows disabling the functionality.
This can be used if deterministic key strokes are required, e.g. for automated tests.
In the future this could be improved in different ways:
* Add some kind of separator in the search list to indicate which elements are at
the top because they have been used recently.
* Store the recent search items per search, instead of in a global list. This way
it could adapt to the user even better.

Avoid confusion when checking for DNA members by using the names
in DNA headers ("Light" instead of "Lamp" for e.g.)
Internally SDNA stores names without aliases for compatibility.
The intention with aliasing DNA names is for `dna_rename_defs.h`
to be the only place where the non-aliased names needed to be referenced
however versioning checks also needed to reference the old names.
This wasn't obvious, causing mistakes in versioning checks (now fixed):
- SpaceOutliner::filter
- BrushGpencilSettings::hardness
- bGPDstroke::hardness
Details:
- Alias lookup tables are now ensured for BlendFileData::filesdna.
- DNA_struct_exists & DNA_struct_member_exists now use aliased names
in versioning code.
Use with_alias / without_alias suffix for functions
so it's clear which is intended (no functional changes).
Add macros for versioning checks to avoid noisy changes,
currently they use the non-aliased versions of these functions
but should eventually be moved to use the aliased versions because
it's confusing to use the original names when these should only need
to be referenced from `dna_rename_defs.h`.
Name the lookup functions to make it clear they are versions of the
non-aliased functions that use an alias.
Prepare for explicit with/without alias versions of functions.
Rename for clarity in preparation for further refactoring.
Remove the need for `_nr` in function names.
- Rename *_find() functions to *_exists() since they returned a boolean.
- Rename *_find_nr() functions to *_find().
- Rename *_struct_elem_* to *_struct_member_*.
- Rename DNA_elem_size_nr -> DNA_struct_member_size.
- Rename DNA_elem_offset -> DNA_struct_member_offset_by_name.
- Use `StringRef` over `StringRefNull`, since it handles `nullptr` in
its constructor and gives more flexibility about the string's source.
- Change `const char *` to `StringRef` as well, for improved ergonomics
and efficiency.
- Move `add_interface_socket_from_node` to a .cc file. It's not small
or performance sensitive enough to be inlined.
- Avoid allocating empty strings for item descriptions.
- Allocate with `BLI_strdupn` to avoid unnecessary `strlen` calls.
- Move a bit more code into a proper namespace.

Rather than always snapping the region size to the closest multiple of
the row height, remember the amount of rows displayed after the user
resized the region, and try to preserve that. This gives a lot more
predictable behavior, especially when the "Show Names" option is toggled
on and off, and the region resizes in response. With the old method the
amount of visible rows could change multiple times while toggling.
This also enables us to clamp the amount of rows (e.g. while the preview
size is increased and the region becomes too large for the area; or,
when a catalog tab is activated with fewer assets and thus fewer rows)
but still restore the amount of rows the user chose earlier, as soon as
possible.

It was possible to access a mutable drawing from a const GreasePencil
object. This sort of mistake is possible because DNA requires using raw
pointers.
In #112326 the socket visibility functions were updated to take the
open/closed state of panels into account for visibility of the socket
icon. However, in "hidden" (collapsed) nodes the panels should be
ignored entirely, drawing all sockets on the root level. This requires
looking at the node flags to determine socket icon visibility, so a
simple method of `bNodeSocket` is not sufficient.
This patch moves the more complex visibility queries for sockets into
`bNode`, where both node and socket flags can be accessed. These should
be used for actual visibility rather than the plain flag accessors on
`bNodeSocket`.
Renamed `is_visible_or_panel_closed` back to just `is_visible`, the
other `is_visible` variant is now integrated in `bNode::is_socket_drawn`.

Add bone collections to the outliner, underneath the Armature.
This basically follows the same approach as the bone groups (which were
removed from the outliner in the previous commit).
Bone groups have been replaced by bone collections. The data in DNA is
there just for versioning & forward compatibility, so the UI elements are
being removed from Blender 4.0.
