Tooltips for assets in the asset shelf now don't only display the name,
but also the description saved in the asset's metadata. This is what we
usually do when assets are displayed, for example in the asset browser
or in add menus. Here it was just a small bit of polish that was never
done.
Fixes an issue with the new node insertion feature where, after a link drag search,
the main input of the new node is connected to, regardless of which one was chosen.

This introduces partial functionality of Precision mode to 'Snap to
Grid'.
However, it behaves differently from 'Absolute Grid Snap', as it lacks
smooth mouse movement.
Precision mode is now available specifically for Transform operations.
Removes many of the operators, panels, and menus used exclusively by Grease Pencil v2 that are no longer needed in v3.
No functional changes are expected.
Some operators are still used by the annotations system and have to be kept around. These may be renamed in future.

Layer panel (also mask/ transform etc.) and other operators are gone
when properties tab is pinned and gpv3 object is non-active.
To fix this, get grease pencil pointer from `button_context()`
(done in `grease_pencil_context()`).

This adds an option `all_keyframes` to the `object.modifier_apply` operator.
With the option enabled, the operator will iterate through all the keyframes,
then apply the modifier and merge the result back into the original
object. This is only done for Grease Pencil objects.
This is how the default `Apply` operation worked in GPv2. This adds the
functionality back but also keeps the current `Apply` behavior for consistency
with other object types.
The UI is also changed to show both options in the dropdown menu.
Again, this is only shown for Grease Pencil objects.
With Geometry Nodes it's possible to add new layers to the geometry.
When applying, this will create a single keyframe on the first frame of
evaluation. Layers with duplicated names in evaluated geometry will
be deduplicated. It's also possible to have layers with empty names.
When applying these get renamed to `Layer` (and `Layer.001` etc.
when such a layer already exists in the original geometry).

The poll function of the Grease Pencil edit undo system was changed by accident to include other
object modes like sculpt mode as well. In the other modes, undo steps wouldn't be created correctly.
Instead, fix the poll function to only allow the Grease Pencil undo system to take over in edit mode.
In all other modes fall back to the global undo system.
Fixes#128566 as well.
Pull Request: https://projects.blender.org/blender/blender/pulls/128573
This adds a function to merge layers in original Grease Pencil geometry.
It also adds an operator to merge layers as well as some tests for the `merge_layers` function.
The operator has 3 modes:
* `Merge Down`: Combine the active layer with the layer just below (if there is one).
* `Merge Group`: Combine all the layers in a group into one single layer and remove
the group. Can be accessed in the right-click menu of groups.
* `Merge All`: Combine all the layers of the object into one single layer.
All of these can be accessed in the `Extras` menu next to the layer tree.
Pull Request: https://projects.blender.org/blender/blender/pulls/128201
This copies the legacy mode toggling operators to a new file
and renames the operators to use the `GREASE_PENCIL_OT` prefix
like the rest of the operators. No functional changes expected.

Implements scrolling support for tree-views, as well as changing the size of the
scroll-able tree-view. This is important to be able to place them in many places
in the UI, where a compact layout is preferred over an every expanding one
(causing following contents to be scrolled out of view). UI-lists would use
scrolling and resizing to ensure this, now tree-views are on par.
Enables scrolling and resizing for:
- Bone collection UI (`UILayout.template_bone_collection_tree()`)
- Grease Pencil layer UI (`UILayout.template_grease_pencil_layer_tree()`)
- Light link collection UI (`UILayout.template_light_linking_collection()`)
- UI to define a node tree interface (`UILayout.template_node_tree_interface()`)
These are all cases where compact UIs make more sense than expanding ones.
Internally this is enabled by calling the `set_default_rows()` method of the
tree-view, although the API might change still. It shouldn't be quite simple to
implement this for grid-views too if necessary, or other potential view types.
Although I'd like to do some smaller code quality improvements still, this
feature is important for some other modules (e.g. grease pencil module for the
layers UI in grease pencil v3), so I decided to prioritize merging this.

Supports the `OB_GREASE_PENCIL` type in the "Join Objects" operator.
Each object is merged into the active object one-by-one. This first
combines the layer trees of the source and destination, adds vertex
groups and materials, and appends the drawings to the destination array.
Then internal references are updated: drawing indices in frame data,
mask layer names, layer parents, material and vertex group indices.
The source curves are transformed into the target object space, so their
world position remains the same. Note that animation data is also
transferred to the new object, but __not__ transformed in case of
diverging object- or layer transforms. This is expected and handled the
same way by other object types.

Generally increases padding of preview widgets a bit (while keeping the
preview size the same), and increases the size of the highlight surface
a bit. The default grease pencil brushes from the essentials asset
library use an opaque background, so the highlight was barely visible
before. It was difficult to identify the active brush from that. Now
it's a lot easier to identify visually.
See PR for comparison screenshots.

This makes link-drag-search more convenient when one wants to insert a new node
between existing nodes. The change currently also affects normal node-insertion
when dragging it. The exact behavior still has to be figured out.

This adds an eyedropper button to properties where you can choose a bone.
Clicking it activates the modal operation and you can pick:
* Bones from the Outliner
* Bones from the 3D Viewport if the Armature is in Pose Mode or Edit Mode
## Limitation
Picking from the 3D viewport while in Object Mode doesn't work due to technical reasons.
The selection buffer is only filled with pose bones if the armature is in pose mode.
Using the picker while in object mode gives you the Armature object, not its bones.
So you cannot use the bone picker to constrain an object to a bone.
UNLESS you pin the panel with the object, go to pose mode and then pick.
There is a warning printed for those cases to tell the user why this hasn't worked.

Supporting selection operators and overlays in sculpt mode is necessary
to support masking operations.
This enables selection drawing in the overlay in sculpt mode,
and ensures all the necessary operators (pick, lasso, circle, box)
handle the differences in modes correctly.
The selection code so far was expecting object mode, so the `vc->obedit`
object was used without further checks. Now the selection code can be
called outside of edit mode, in which case the `vc->obact` object must
be used instead. Similarly edit mode and sculpt mode have separate
`selectmode` flags, so the correct mode property must be used from the
tool settings depending on the object mode. These changes require some
refactoring of unrelated selection code.

This does some changes to the ed::greasepencil::ensure_active_keyframe` function.
* The context was only needed to get the scene, pass the scene directly
* Don't use the active layer by default but pass a reference to a
layer instead. This makes it also possible to create keyframes
on multiple layers using a loop.
This adds a new type of zone to Geometry Nodes that allows executing some nodes
for each element in a geometry.
## Features
* The `Selection` input allows iterating over a subset of elements on the set
domain.
* Fields passed into the input node are available as single values inside of the
zone.
* The input geometry can be split up into separate (completely independent)
geometries for each element (on all domains except face corner).
* New attributes can be created on the input geometry by outputting a single
value from each iteration.
* New geometries can be generated in each iteration.
* All of these geometries are joined to form the final output.
* Attributes from the input geometry are propagated to the output
geometries.
## Evaluation
The evaluation strategy is similar to the one used for repeat zones. Namely, it
dynamically builds a `lazy_function::Graph` once it knows how many iterations
are necessary. It contains a separate node for each iteration. The inputs for
each iteration are hardcoded into the graph. The outputs of each iteration a
passed to a separate lazy-function that reduces all the values down to the final
outputs. This final output can have a huge number of inputs and that is not
ideal for multi-threading yet, but that can still be improved in the future.
## Performance
There is a non-neglilible amount of overhead for each iteration. The overhead is
way larger than the per-element overhead when just doing field evaluation.
Therefore, normal field evaluation should be preferred when possible. That can
partially still be optimized if there is only some number crunching going on in
the zone but that optimization is not implemented yet.
However, processing many small geometries (e.g. each hair of a character
separately) will likely **always be slower** than working on fewer larger
geoemtries. The additional flexibility you get by processing each element
separately comes at the cost that Blender can't optimize the operation as well.
For node groups that need to handle lots of geometry elements, we recommend
trying to design the node setup so that iteration over tiny sub-geometries is
not required.
An opposite point is true as well though. It can be faster to process more
medium sized geometries in parallel than fewer very large geometries because of
more multi-threading opportunities. The exact threshold between tiny, medium and
large geometries depends on a lot of factors though.
Overall, this initial version of the new zone does not implement all
optimization opportunities yet, but the points mentioned above will still hold
true later.

This affects the edit-mode copy/paste operators as well as the sculpt
mode _Clone_ tool. These copy and paste to/from the clipboard, but were
not applying the layer transform in the process. All curves were stored
in their respective local layer space. Since everything gets merged
these transforms get lost when storing to the clipboard.
Pasting curves from the clipboard was also not applying the target layer
transform. Also the clipboard content was getting pasted into every
editable drawing.
Now clipboard curves are always stored in world space. Pasting only
happens on the active layer, and the active layer inverse transform is
applied so visual transform of curves shouldn't change through copy and
paste.

Integrate an existing implementation of the SLIM unwrapping algorithm
into Blender. More info about SLIM here:
https://igl.ethz.ch/projects/slim/
This commit is based on the integration code written by Aurel Gruber
for Blender 2.7x (unfinished and never merged with the main branch).
This commit is based on Aurel's code, rebased and further improved.
Details:
- Unwrap has been moved into a sub-menu,
slim unwrapping is exposed as: "Minimum Stretch".
- Live unwrap with SLIM refines the solutions using a timer.
- When using SLIM there are options to:
- Set the number of iterations.
- Weight the influence using vertex weights.
- SLIM can be disabled using the `WITH_UV_SLIM` build option.

There were some issues with the operator:
* The `keep_original` option could easily crash blender.
* The surface projection did not work correctly.
This commits fixes those issues. The `keep_original` was
missing a tag for the topology that changes in the
drawing. The surface projection needed to cache the
viewport depths. This is done once and then used
to initialize the `DrawingPlacement`.
This commit adds low-level logic in BKE to support three behaviors in
case of name conflict when renaming an ID:
1. Always tweak new name of the renamed ID (never modify the other ID
name).
2. Always set requested name in renamed ID, modifying as needed the
other ID name.
3. Only modify the other ID name if it shares the same root name with the
current renamed ID's name.
It also adds quite some changes to IDTemplate, Outliner code, and
RNA-defined UILayout code, and the lower-level UI button API, to allow
for the new behavior defined in the design (i.e. option three from above list).
When renaming from the UI either 'fails' (falls back to adjusted name) or forces
renaming another ID, an INFO report is displayed.
This commit also fixes several issues in existing code, especially
regarding undo handling in rename operations (which could lead to saving
the wrong name in undo step, and/or over-generating undo steps).
API wise, the bahavior when directly assigning a name to the `ID.name`
property remains unchanged (option one from the list above). But a new
API call `ID.rename` has been added, which offers all three behaviors.
Unittests were added to cover the new implemented behaviors (both at
BKE level, and the RNA/Py API).
This commit implements #119139 design.

The function would return two very different layouts in different code
paths, making it not clear to the caller what to expect. For one code
path the return value was rather useless, and in fact unused, so I was
able to just remove this. Also clarified behavior and return values in
the function API comment.
Since 5bcb0c9935, `uiLayout.template_ID()` already supports passing a label, in
which case the `uiLayout.use_property_split` would be respected. This makes the
template fit nicely with the surrounding layout, where buttons might have a
label split on the left, and a decorator button on the right.
This change brings the same to `uiLayout.template_search()`, plus makes it
respect `uiLayout.use_property_decorate`
