This adds support for showing geometry passed to the Viewer in the 3d
viewport (instead of just in the spreadsheet). The "viewer geometry"
bypasses the group output. So it is not necessary to change the final
output of the node group to be able to see the intermediate geometry.
**Activation and deactivation of a viewer node**
* A viewer node is activated by clicking on it.
* Ctrl+shift+click on any node/socket connects it to the viewer and
makes it active.
* Ctrl+shift+click in empty space deactivates the active viewer.
* When the active viewer is not visible anymore (e.g. another object
is selected, or the current node group is exit), it is deactivated.
* Clicking on the icon in the header of the Viewer node toggles whether
its active or not.
**Pinning**
* The spreadsheet still allows pinning the active viewer as before.
When pinned, the spreadsheet still references the viewer node even
when it becomes inactive.
* The viewport does not support pinning at the moment. It always shows
the active viewer.
**Attribute**
* When a field is linked to the second input of the viewer node it is
displayed as an overlay in the viewport.
* When possible the correct domain for the attribute is determined
automatically. This does not work in all cases. It falls back to the
face corner domain on meshes and the point domain on curves. When
necessary, the domain can be picked manually.
* The spreadsheet now only shows the "Viewer" column for the domain
that is selected in the Viewer node.
* Instance attributes are visualized as a constant color per instance.
**Viewport Options**
* The attribute overlay opacity can be controlled with the "Viewer Node"
setting in the overlays popover.
* A viewport can be configured not to show intermediate viewer-geometry
by disabling the "Viewer Node" option in the "View" menu.
**Implementation Details**
* The "spreadsheet context path" was generalized to a "viewer path" that
is used in more places now.
* The viewer node itself determines the attribute domain, evaluates the
field and stores the result in a `.viewer` attribute.
* A new "viewer attribute' overlay displays the data from the `.viewer`
attribute.
* The ground truth for the active viewer node is stored in the workspace
now. Node editors, spreadsheets and viewports retrieve the active
viewer from there unless they are pinned.
* The depsgraph object iterator has a new "viewer path" setting. When set,
the viewed geometry of the corresponding object is part of the iterator
instead of the final evaluated geometry.
* To support the instance attribute overlay `DupliObject` was extended
to contain the information necessary for drawing the overlay.
* The ctrl+shift+click operator has been refactored so that it can make
existing links to viewers active again.
* The auto-domain-detection in the Viewer node works by checking the
"preferred domain" for every field input. If there is not exactly one
preferred domain, the fallback is used.
Known limitations:
* Loose edges of meshes don't have the attribute overlay. This could be
added separately if necessary.
* Some attributes are hard to visualize as a color directly. For example,
the values might have to be normalized or some should be drawn as arrays.
For now, we encourage users to build node groups that generate appropriate
viewer-geometry. We might include some of that functionality in future versions.
Support for displaying attribute values as text in the viewport is planned as well.
* There seems to be an issue with the attribute overlay for pointclouds on
nvidia gpus, to be investigated.

Comments there weren't really helpful, took me a while to get what they
try to say. This attempts to add a better explanation. Also add an
assert for a previous, implicit (but commented) assumption, and some
minor cleanups.
Was always creating a copy of `SpaceOutliner`, even though it's only
needed for one conditional branch. This is a shallow copy, so shouldn't
be that expensive, still trivial to avoid.
This is old code to keep track of an active search element, so you could
step through the search results. This isn't used anymore, and not needed
since searching now filters the tree to only show matches. If we ever
wanted to have support for stepping through elements again, that should be
done via the active element instead.
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.

The main goal of this refactor is to make BPath module use `IDTypeInfo`,
and move each ID-specific part of the `foreach_path` looper into their
own IDTypeInfo struct, using a new `foreach_path` callback.
Additionally, following improvements/cleanups are included:
* Attempt to get better, more consistent namings.
** In particular, move from `path_visitor` to more standard `foreach_path`.
* Update and extend documentation.
** API doc was moved to header, according to recent discussions on this

* Remove `BKE_bpath_relocate_visitor` from API, this is specific
callback that belongs in `lib_id.c` user code.

Two issues addressed here:
I) `asset_type_info` is sub-data, not a callback. Therefore, move it
before the callbacks in the `IDTypeInfo` struct.
II) More important, initialize this new attribute in *ALL* `IDTypeInfo`
instances. No member of this struct should ever be left implicitely
uninitilazed, ever.
Aftermath of rBa84f1c02d251.
Previously, `ImageTile->ok` and `ImageUser->ok` were used to indicate
whether an image failed to load. There were three possible values
which (probably) had the following meanings:
* `0`: There was an error while loading the image. Don't try to load again.
* `1`: Default value. Try to load the image.
* `2`: The image was loaded successfully.
This image-wide flag did not make sense unfortunately, because loading
may work for some frames of an image sequence but not for others.
Remember than an image data block can also contain a movie.
The purpose of the `->ok` flag was to serve as an optimization to avoid
trying to load a file over and over again when there is an error (e.g. the
file does not exist or is invalid). To get the optimization back, the patch
is changing `MovieCache` so that it can also cache failed load attempts.
As a consequence, `ibuf` is allowed to be `NULL` in a few more places.
I added the appropriate null checks.
This also solves issues when image sequences are used with the
Image Texture node in Geometry nodes (also see D12827).

Draw thumbnails as strip overlay. This works for movie and image strips.
To draw thumbnails, this overlay has to be enabled and strips must be
tall enough.
The thumbnails are loaded from source file using separate thread and
stored in cache.
Drawing code uses only images stored in cache, and if any is missing,
background rendering job is started. If job can not render thumbnail,
to prevent endless loop of creating job for missing image it sets
`SEQ_FLAG_SKIP_THUMBNAILS` bit of `Sequence` flag.
To prevent visual glitches during timeline panning and zooming, `View2D`
flag `V2D_IS_NAVIGATING` is implemented. If bit is set, drawing code
will look for set of evenly distributed thumbnails that should be
guaranteed to exist and also set of previously displayed thumbnails.
Due to volatile nature of cache these thumbnails can be missing anyway,
in which case no new thumbnails will be drawn for particular strip.
Cache capacity is limited to 5000 thumbnails and performs cleanup of
non visible images when limit is reached.

Add needed extra flag and utils to IDType to mark and check an ID type
as only appendable.
Note that this is only a loose user-level enforcement currently, in any
case you need to be able to link an ID to append it currently, so for
low-level code this does not really matter.
Currently only WorkSpace and Screen ID types are marked with the new
`IDTYPE_FLAGS_ONLY_APPEND` flag.
Essentially, Workspace (and Screen) types were defined as not
localizable.
In previous code it happended to work by mere chance (code path taken in
`BKE_library_make_local` was conviniently skipping the call to
`BKE_lib_id_make_local` in that case, hence not checking for
`IDTYPE_FLAGS_NO_MAKELOCAL` flag of the localized ID type).
This is a total abuse of this IDType flag, for now removing it.
That specific case (IDtype appendable but nor linkable) requires its own
proper flag, this will be tackled in a later commit.
Issue introduced in rB3be5ce4aad5e.
This was not really useful, and added estra useless steps in case and ID
should not actually be written.
Further more, it prevented clearing the usercount on write, which can be
cause a false positive 'chanhged' detection in undo/redo case.
This is more of a first-pass refactor for the UI list template. More
improvements could be done, but that's better done separately. Main
purpose of this is to make the UI list code more manageable and ready
for the asset view template.
No functional changes for users.
* Split the huge template function into more manageable functions, with
clear names and a few structs with high coherency.
* Move runtime data management to the template code, with a free
callback called from BKE. This is UI data and should be managed at
that level.
* Replace boolean arguments with bit-flags (easily extendable and more
readable from the caller).
* Allow passing custom-data to the UI list for callbacks to access.
* Make list grip button for resizing optional.
* Put logic for generating the internal UI list identifier (stored in
.blends) into function. This is a quite important bit and a later
commit adds a related function. Good to have a clear API for this.
* Improve naming, comments, etc.
As part of further cleanups I'd like to move this to an own file.
When renaming an ID somewhere in the UI after marking it as asset, it would
often get lost in the Asset Browser (scrolled out of view). It would also get
deactivated.
This patch makes sure that if an asset is active whose ID gets renamed, it is
kept active and visible. That is important for a fast, uninterrupted asset
creation workflow, where users often rename assets while working in the asset
browser.
Old code stored the new file-name to identify a file after re-reading the
file-list after the rename. For assets that doesn't work because there may be
multiple assets with the same name. Here the simple solution of just storing
the pointer to the renamed ID is chosen, rather than relying on the file-name
in this case. (Should be fine with undo, since the ID * reference is short
lived, it's not stored over possible undo steps. If it turns out to have
issues, I rather switch to a rename_id_uuid, but keep that separate from the
file->uid).

The depth cache (located in `RegionView3D::depths`) is used for quick
and simple occlusion testing in:
- particle selection,
- "Draw Curve" operator and
- "Interactive Light Track to Cursor" operator,
However, keeping a texture buffer in cache is not a recommended practice.
For displays with high resolution like 8k this represents something
around 132MB.
Also, currently, each call to `ED_view3d_depth_override` invalidates
the depth cache. So that depth is never reused in multiple calls from
an operator (this was not the case in blender 2.79).
This commit allows to create a depth cache and release it in the same
operator. Thus, the buffer is kept in cache for a short time, freeing
up space.
No functional changes.
This patch adds support for filtering rows based on rules and values.
Filters will work for any attribute data source, they are a property
of the spreadsheet rather than of the attribute system. The properties
displayed in the row filter can depend on data type of the currently
visible column with that name. If the name is no longer visible, the
row filter filter is grayed out, but it will remember the value until
a column with its name is visible again.
Note: The comments in `screen.c` combined with tagging the sidebar
for redraw after the main region point to a lack of understanding
or technical debt, that is a point to improve in the future.
**Future Improvements**
* T89272: A search menu for visible columns when adding a new filter.
* T89273: Possibly a "Range" operation.

Clear the runtime data structs instead of individual members,
this simplifies adding new runtime members as there are at least
two places they would need to be cleared.
Resolves error in D8883.
This introduces a context path to the spreadsheet editor, which contains
information about what data is shown in the spreadsheet. The context
path (breadcrumbs) can reference a specific node in a node group
hierarchy. During object evaluation, the geometry nodes modifier checks
what data is currently requested by visible spreadsheets and stores
the corresponding geometry sets separately for later access.
The context path can be updated by the user explicitely, by clicking
on the new icon in the header of nodes. Under some circumstances,
the context path is updated automatically based on Blender's context.
This patch also consolidates the "Node" and "Final" object evaluation
mode to just "Evaluated". Based on the current context path, either
the final geometry set of an object will be displayed, or the data at
a specific node.
The new preview icon in geometry nodes now behaves more like
a toggle. It can be clicked again to clear the context path in an
open spreadsheet editor.
Previously, only an object could be pinned in the spreadsheet editor.
Now it is possible to pin the entire context path. That allows two
different spreadsheets to display geometry data from two different
nodes.
The breadcrumbs in the spreadsheet header can be collapsed by
clicking on the arrow icons. It's not ideal but works well for now.
This might be changed again, if we get a data set region on the left.

A `DataSource` provides columns for the spreadsheet to display.
Every column has a SpreadsheetColumnID as identifier. Columns
are not generated eagerly anymore, instead the main spreadsheet
code can request a column from a data source with an column
identifier. The column identifiers can be stored in DNA and allow us
to store persistent data per column.
On the user level the only thing that changes is that columns are
not shown in alphabetical order anymore. Instead, new columns
are always added on the left. The behavior can be changed,
however I'd prefer not to automate this too much currently. I think
we should just add operators to hide/reorder/resize columns soonish.

This implements the MVP for the new spreadsheet editor (T85879). The functionality
is still very limited, but it proved to be useful already. A more complete picture
of where we want to go with the new editor can be found in T86279.
Supported features:
* Show point attributes of evaluated meshes (no original data, no other domains,
no other geometry types, yet). Since only meshes are supported right now, the
output of the Point Distribute is not shown, because it is a point cloud.
* Only show data for selected vertices when the mesh is in edit mode.
Different parts of Blender keep track of selection state and original-indices with
varying degrees of success. Therefore, when the selected-only filter is used, the
result might be a bit confusing when using some modifiers or nodes. This will
be improved in the future.
* All data is readonly. Since only evaluated data is displayed currently, it has to
be readonly. However, this is not an inherent limitation of the spreadsheet editor.
In the future editable data will be displayed as well.
Some boilerplate code for the new editor has been committed before in
rB9cb5f0a2282a7a84f7f8636b43a32bdc04b51cd5.
