This was reported in T90026 for attributes, but was also true for:
- UVMaps
- Vertex Colors
- Sculpt Vertex Colors
- Face Maps
For Vertex groups and Shapekeys this was already done (in that their
remove poll would check if there is a vertex group or shapekey to begin
with), now make this consistent across all mentioned types.
Thx @vvv for the initial patch (where this was done for attributes only)

I'm trying to move away from general files with lots of things in them,
and instead have many small & focused files. I find that easier to
work with since everything has clear responsibilities, even if there is
some minor overhead in managing all these files.
I also try to differentiate more clearly between public and internal
files. So source files and internal headers are in a `intern/`
sub-directory, public functions are in a number of headers one level
higher.
For convenience and to make this compatible with our existing general
headers in `editors/include`, I made the `ED_asset.h` there include all
these public headers.
This is of course a bit of an experiment, let's see how it works in
practice.
Also corrected the name of `ED_asset_can_make_single_from_context()`.
This was an open TODO, I wanted to have code for translating asset
library references from and to enum values in a central place, and
access that in the same way from both the Asset Browser and the
Workspace RNA code.
* Adds own file for the related functions.
* Adds doxygen comments.
* Updates RNA callbacks to properly use these functions.
* Let these functions call each other, avoid duplicating logic.
Since recently it's possible to access assets from outside the
File/Asset Browser, via the asset view template. So we are slowly
moving away from file space specific code to dedicated asset system
code. I introduced `AssetLibraryReference` as a duplicate of
`FileSelectAssetLibraryUID`, with a plan to delete the latter in a
separate cleanup commit. That's exactly what this commit is.
This will cause Asset Browsers to open with the default "Current File"
Asset Library. We could avoid that, but it's a minor issue really.
This new variable was introduced with 7898089de3. We don't usually use
an `active` prefix variable. Plus, this makes the name match the one of
the Asset Browser active library variable, so we can use the
`rna_def_asset_library_reference_common()` helper for both.
This will cause Asset Views to open with the default "Current File"
Asset Library. We could avoid that, but it's a minor issue really.
Would previously pass a few properties that are available via the
asset-handle now. This asset-handle is also required for some of the
asset API, e.g. the temporary ID loading. This will probably be needed
before too long.
For this to work, the utility function needs to be callable without
context, which is only needed for a File Browser specific hack anyway
(doesn't apply to this usage of it).
While the asset-handle design is supposed to be temporary (see
35affaa971), I prefer keeping the fact that it's nothing but a file
entry pointer an implementation detail that is abstracted away. So this
introduces getters for the file data we typically access for
asset-handles.
Remove the assumption of the pose library that Action groups are named
after the bones in the armature. Even though this assumption is correct
when the keys are created by Blender, action groups can be renamed. Keys
created by Python scripts can also use arbitrary group names.
Since there is more code in Blender making this assumption, and looping
over selected bones is also a common occurrence, this commit contains
some generic functionality to aid in this:
- `BKE_armature_find_selected_bones`: function that iterates over all
bones in an armature and calls a callback for each selected one. It
returns a struct with info about the selection states (all or no bones
selected).
- `BKE_armature_find_selected_bone_names(armature)` uses the above
function to return a set of selected bone names.
- `BKE_pose_find_fcurves_with_bones()` calls a callback for each FCurve
in an Action that targets a bone, also passing it the bone name.
Convert `pose_backup.c` (in C) to `pose_backup.cc` (in C++). This will
make future improvements easier. For now, it's the same code with just
some additional explicit casts (C++ doesn't allow implicitly casting
`void *`), `NULL` changed into `nullptr`, and some other simple changes.
No functional changes.
Function signatures for snap callbacks used `const` incorrectly
which was hidden by casting function types.
This made it seem as if the input arguments wouldn't be change and
wouldn't be initialized.
Name return arguments with an `r_` prefix, order them last,
remove function casts and correct `const` usage.
Although currently only the asset list code uses the asset library
reference wrapper, it can stand on its own and may be used in more
places in the future. So I prefer to give it its own source & header
file.
Also removed unused includes, added proper namespaces as per our C++
style guidelines, and removed an unnecessary TODO comment.
No operator or macro should be missing description. But if they do, then
they should use NULL pointer, and not an empty string.
This behavior was already enforced (through an assert) for operators,
previous commit made it the same for macros.
Scaling down images could create images with a width or height of zero.
Clamp at 1 to prevent a crash, also add an assert to scaling functions.

We need to be more strict about trying to retrieve a list of vertex group
names from objects now, as only three object types support them.
This commit adds a check for vertex group support in a few places, the
data transfer operator/modifier, copying vertex groups to selected
objects, and the vertex group remove and clear functions.

The `action_preview_render()` function used to just render, but now it
also temporarily applies the pose. Its comment is now updated for this.
No functional changes.
In driver editor, vertically flip the value debug lines to align
them with the timeline header values. This makes it easier to read
the values. Also set the line width explicitly, which was incorrect
in some cases.

This move was already prepared with 788d380460 and 26b098c04f. The
template is quite big already, better to give it its own file. Plus it
could use some C++ features like RAII and maybe some more object
oriented code. I plan further refactoring there.
The asset view UI template is a mini-version of the Asset Browser that
can be placed in regular layouts, regions or popups. At this point it's
made specifically for placement in vertical layouts, it can be made more
flexible in the future.
Generally the way this is implemented will likely change a lot still as
the asset system evolves.
The Pose Library add-on will use the asset view to display pose
libraries in the 3D View sidebar.

Notes:
* Important limitation: Due to the early & WIP implementation of the
asset list, all asset views showing the same library will show the
same assets. That is despite the ID type filter option the template
provides. The first asset view created will determine what's visible.
Of course this should be made to work eventually.
* The template supports passing an activate and a drag operator name.
The former is called when an asset is clicked on (e.g. to apply the
asset) the latter when dragging (e.g. to .blend a pose asset). If no
drag operator is set, regular asset drag & drop will be executed.
* The template returns the properties for both operators (see example
below).
* The argument list for using the template is quite long, but we can't
avoid that currently. The UI list design requires that we pass a
number of RNA or custom properties to work with, that for the Pose
Libraries should be registered at the Pose Library add-on level, not
in core Blender.
* Idea is that Python scripts or add-ons that want to use the asset view
can register custom properties, to hold data like the list of assets,
and the active asset index. Maybe that will change in future and we
can manage these internally.
As an example, the pose library add-on uses it like this:
```
activate_op_props, drag_op_props = layout.template_asset_view(
"pose_assets",
workspace,
"active_asset_library",
wm,
"pose_assets",
workspace,
"active_pose_asset_index",
filter_id_types={"filter_action"},
activate_operator="poselib.apply_pose_asset",
drag_operator="poselib.blend_pose_asset",
)
drag_op_props.release_confirm = True
drag_op_props.flipped = wm.poselib_flipped
activate_op_props.flipped = wm.poselib_flipped
```
