Finding the boundary uses a Moore neighborhood. The algorithm iterates
over filled pixels, following pixels with empty neighbors, in clockwise
direction. For a given pixel and input direction (where the boundary is
coming from), the next neighbor is found by checking neighbors clockwise
from the previous pixel.
The last direction in this inner loop would be opposite the input
direction, i.e. if the pixel has only one neighbor it can loop back
and iterate over pixels that are already in the boundary, from the
opposite direction. However, this last direction was excluded from the
search (an earlier implementation did not support it). Using this search
direction as well allows the boundary to go back and forth over the same
line of pixels until the boundary is closed.

This PR adds the `Line Face Set` tool and adds it to the following
location:
* Sculpt Mode toolbar
## Limitations
None of the existing Face Set gesture operators exist in either the
Sculpt dropdown or the Face Set dropdown, this PR does not add the Line
Face set tool in either location as well.
Pull Request: https://projects.blender.org/blender/blender/pulls/122245
This PR adds a new operator: `PAINT_OT_visibility_edit` to support
iteratively expanding or shrinking the visibility of a mesh, similar to
the *Grow / Shrink Mask* actions and the *Grow / Shrink Face Set*
options. This operator is exposed via two new entries in the *Sculpt*
toolbar entry as *Show More* and *Show Less* and have also been
assigned to Page Up and Page Down in the default Blender keybinds for
Sculpt Mode.
### Technical Details
Each of the PBVH types is solved slightly differently, though the
general principle for each is as follows:
1. Make a copy of the current mesh visibility state
2. Iterate over elements (faces & corners if available, otherwise
vertices) to look at adjacency information
3. Apply appropriate visibility change to vertices
4. Sync face visibility
### Limitations
* Currently, like all other operators in the `paint_hide.cc` file. This
new operator is limited to Sculpt mode only.

The "render_stats" handler now includes the message line that was
written to stdout as the first arg (using `BKE_callback_exec_string`
instead of just `BKE_callback_exec_null`).
This can be useful to track render progress (and people were relying on
parsing stdout in the past).
Was a request in chat.
This also corrects possible output from the callback being written in
between message parts in `do_write_image_or_movie` (which was probably a
mistake in 93d5e106aa).

The `overlay_wireframe` shaders uses a `nor` input but it wasn't added
to the GPU batch since the normals were split to a separate vertex buffer.
Adding that input gets closer to the appearance in 4.0. But it still looks a
bit different-- the outline is not as bright overall.
Fixes#120781.

As Node Wrangler add-on is moving to extensions platform and maybe isn't shipped
with Blender from 4.2 onwards, some of it's more important functionalities which are
crucial for Blender UX can be ported inside core. Also see #121749.
This PR ports "Preview Node" operator from add-on inside `scripts/startup/bl_operators`.
When Shift-Ctrl (or Shift-Alt) clicked on the node operator connects output socket of the
node to active Output node in the tree (group, material, light, or world output). For Geometry
Nodes this is just handy operator, but in Shader Nodes, because Viewer Node isn't
implemented, this has always been the only way to quickly preview nodes by connecting
it to Material Output.
Changes made from Node Wrangler version:
- Renamed operator from "Preview Node" to "**Connect to Output**", because node previews
already mean a different thing in context of compositor and shader editor, and viewer node
is used for previewing in geometry nodes. Connect to Output is correct name because in every
context it's called that's what it does.
- Assigned shortcut Shift-Alt-Click in shader editor as well. Even though Shift-Ctrl click already
works, it's good to have consistency with geometry nodes, so that users can use same shortcut
in both contexts.
Operator doesn't work in compositor. It's not clear if that's wanted (to connect to Composite node),
and if it is it'll be added in separate PR.

This node allows replacing the transformation of every instance by providing a matrix.
Before, this was only possible by using the Store Named Attribute node. It's more common
in Blender to have specialized built-in nodes for built-in attributes (e.g. Set Position, and Set ID).

While easier to understand, the conventionnal global
scene thickness parameter have some downside:
- It doesn't scale with larger scenes since the
distant samples have small thickness
- It doesn't handle fine geometric variation in
foreground.
The proposed angular thicknes makes all sample
have the same angular span. This makes it
distance independant and capture different occluder
thickness with less artifacts. The downside is
that the occluders have the same angular span
at any distance which makes the same occluder inflate
with distance.
A downside is that the geometry near the shading point is
under-represented. Leaving light leaking or lack of AO
at contact points. To fix this, we introduce back a
geometric thickness parameter.

Previously, the workflow was triggered by **opened pull requests** events.
However, testing revealed that this event, initiated by external GitHub users,
lacks the permission scope to comment on or close pull requests.
To address this, I've updated the workflow to trigger on a schedule. Scheduled
triggers aren't tied to external actors, thereby ensuring the necessary
permission scopes are available.

This allows using strokes with a "Dot" material as boundaries for the
fill tool.
Note: "Square" materials are not currently supported, they get rendered
as dots too. This is the same in GPv2, there just isn't a simple shader
for rotated squares.

The "Maximum Gap" setting for the "Natural Drawing Speed"
mode was not working.
This was because the code used `math::max` to try and clamp the value
to a maximum when it should have used `math::min`.
This fixes this issue.
Volumes and grids were not yet handled by the Geometry Nodes value
logging system. This patch adds basic information (number of grids)
to the value logger and node tooltips.

This is slight optimization. Number of nodes with additional outputs like `Valid`
flag of other math-related things will be more in future, its better to strict api
and do not evaluate even singles. This also can reduce number of logged values.

The issue was that the code called a function that doesn't
check for the active keyingset in combination with autokeying.
The fix is to just call `autokeyframe_pose_channel` which does that check.
I snuck in a minor change to the operator label.
It spells out "Quaternions" now instead of shortening to "Quats".
I haven't seen that way to shorten it in Blender before.

The issue was that when adding a constraint through
python to an object that is already animated,
the constraint did not evaluate properly at first.
The fix is to update the depsgraph when creating a
constraint through the API.
Such an update already happened when running the
operator to create a constraint.

The Probot configuration we previously used to auto-close PRs (and Issues) on
GitHub is no longer functioning. To address this, I've created a GitHub Actions

immediately (0 days) and are subsequently closed right away (0 days).

Previously they were split between two places, and were not fully
consistent with each other. The inconsistency didn't result in
user-facing inconsistency due to what was called when at a higher
level, but this will ensure continued user-facing consistency as we make
more changes to the keyframing code.

This patch adds support for timing GPU compositor executions. This was
previously not possible since there was no mechanism to measure GPU
calls, which is still the case. However, since 2cf8b5c4e1, we now flush
GPU calls immediately for interactive editing, so we can now measure the
GPU evaluation on the host, which is not a very accurate method, but it
is better than having no timing information. Therefore, timing is only
implemented for interactive editing.
This is different from the CPU implementation in that it measures the
total evaluation time, including any preprocessing of the inputs like
implicit type conversion as well as things like previews.
The profiling implementation was moved to the realtime compositor since
the compositor module is optional.

The loose edge section of the index buffer was built incorrectly,
essentially assuming that all the hidden edges came at the end of the
loose edge indices. To correct this, we need to track the visibility of
each loose edge index rather than the visibility of each edge itself.
This is driven by the need to combine the loose and non-loose indices
into one IBO with the loose edges in a contiguous section, and the
desire to avoid restart "invisible" indices in the buffer to upload
less data to the GPU.
Refreshing refers to the recreation of the block and it's buttons in
this case.
Refreshing popup regions on text input was added in 7d80fde033. It can
be useful to update the popup contents on text input, searchboxes have
their completely own update handling however.
These popups had refreshing enabled, but the callback used for
refreshing would access a likely dangling operator pointer. One case can
use the operator-type pointer instead, in the other case disable
refreshing altogether. Also see 8ea79dc3a7.
