This should not be allowed in general, added some initial call to check
when user is allowed to delete a data to search for mandatory override
usages...
Own mistake when making NLA overridable, instead of assuming things
about the ID owner of the animation data being processed, properly
return and use the one found by `ED_actedit_animdata_from_context`.
Use dashes to represent the function flow (while keeping continuous
lines for the data-flow).
It is important to tell both flows apart (the data and the function
flow). The sockets help with that, the noodles help this further.
The "data flow" is evaluated at every single node. A user can inspect
the output sockets of those nodes and have a glimpse at their values.
The "function flow" (nodes) however is only evaluated in the geometry
nodes. The noodles are not transporting data in the same sense of the
"data flow". All that can be inspected are the attributes the functions
depend on.
Having this clearly communicated should help users to inspect the
nodetrees, read and understand the different flows in the same tree.
---
Known limitations:
At the moment the dash lines are not equidistant:
* It would be nice to get the "uv.x" to be resampled for the bezier curve
so the dashes are equally distributed in the curve.
* Using distance between the P3 and P0 instead of the real bezier curve
length seems to be fine.
---
Full disclaimer:
Changes with that much of a visual impact tend to be controversial. So
far the main feedback is that dashed lines can be associated to broken
link, and that there are better ways to represent the flows (or
different information that should be visually represented).
I'm fully aware of that. However dashed lines are already used in the
viewport and outliner to indicate (hierarchical) relation. Besides,
other approaches (double-lines, having the data flow to be more
distinct, ...) didn't pan out in the end (or didn't look as good as
this).
---
Impact in other editors:
The compositor uses mostly a "data flow" nodetree, so no change is
expected there.
The shader nodetree is one that could but doesn't have to change its
visual language.
The shader nodetree uses mostly "function flow" with some "data flow" nodes.
One can argue that it should be adapted to follow the
same pattern as geometry nodes (with the new noodles and the diamond
sockets). Oh the other hand, a shader nodetree has a single context.
When a node depends on the "UV", there is only one UV at a time for the
entire nodetree. So it can also be treated as a psedo "data flow"
nodetree if we want to avoid too many changes in other parts of Blender.

NLA and Dope Sheet use a specific transform operation to scale.
Unlike the conventional resize operation, `TIME_SCALE` operates on `td->val`.
This is a bit outside the convention of transform operators.
The expected thing in this case would be to work in `td->loc` and use the conventional resize operator.
But for now, to fix the problem, use `td->loc` in the `TIME_SCALE` operation.
This commit also brings a cleanup in the style of some comments and removing unnecessary `memset`.
The Clear Asset operator (`ASSET_OT_clear`) now clears the Fake User.
This makes it symmetrical with the Mark Asset (`ASSET_OT_mark`)
operator, which sets Fake User to ensure assets are always saved to
disk.
Clear Asset now also has a `set_fake_user` boolean option, which allows
users to Clear Asset and set Fake User in one go.
The asset browser now shows these options in the context menu:
- Clear Asset: also clears Fake User. This makes it possible to actually
remove assets from the blend file without leaving the Asset Browser.
- Clear Asset (Set Fake User): keeps the Fake User bit set. This makes
it possible to "hide" the asset from the asset browser, without
loosing the actual data.
Internally, the `ED_asset_clear_id(id)` function now always clears the
Fake User bit. If it was intended that this bit was kept set, it's up to
the caller to explicitly call `id_fake_user_set(id)` afterwards.

Currently the Drivers Editor shows this (the blue thing can be dragged
to change frame):
{F10647661}
But the Drivers Editors X axis is the output of the driver [which can be
further tweaked by the curve] not time(frame).
So it seems better to not mix them here, it is just confusing to have
two different units on one axis.
Especially since what we really want to look at in X (the drivers output
value) can be in a totally unrelated range compared to frames, so e.g.
we might be interested in a drivers range from 0.0 to 1.0 and a
framerange of 100 to 200, so putting this on one axis just does not make
sense. Better to use a separate timeline for this.

Labels in headers reserved space for an icon even when no icon was used.
This is caused by the shared function ui_text_icon_width adding 1.5x
a buttons X-units width the the width of the string.
Menu buttons detected this and subtracted the extra padding.
Instead of adding the same workaround for labels,
add ui_text_icon_width_ex that takes a padding argument.
Add presets for 'default', 'compact' and 'none' to avoid duplicating
padding values.
This allows removal of hard-coded label scaling for the add-object tool.

Basically this enables the select-tweaking behavior as per the

We use this in most other other editors that allow selecting and

into an asset catalog for the upcoming asset catalog UI.
`BKE_object_material_slot_used` would only check obdata usages, but
particle settings can also (weirdly enough) use objects' material slots.
So now, as its name suggests, `BKE_object_material_slot_used` does take
an object as parameter, and also checks for potential slot usage from
psys in the object.
This makes it easier to spot which links contain fields and which
contain data. Actually, the patch makes all other links a bit thicker.
However, with soon-to-be-implemented theme changes, the
perceived thickness will be the same as before.

Since its introduction in {rB5c569d227b64}, the view roll was based on
horizontal movement only. Using a "real" angle not only feels more
natural but also has the benefit of getting more precission the further
away from the center you are (just like regular rotation, brush/stencil
rotation etc.). A similar thing has already been implemented in the
Grease Pencil Tools Addon, now make the blender standard roll the same.
Since this is not using the transform system, we are still lacking a
line in the viewport (this could be added but since this is always based
on the center of the view we dont necessarily need this), as well as the
additional Shift-extra-precission behavior.

Until now, the asset catalogs would only show up after all assets from
the library were loaded. Now the catalogs are read first, which makes
them appear pretty much immediately. This makes the UI more responsive
and feel less heavy.
I added a dedicated file-list type for asset libraries now. While not
necessarily needed, I prefer that so asset library specific stuff can be
handled in there.
This adds initial limited support for socket tooltips. It's limited
in a couple of ways for now:
* Only works when hovering over the socket shape, not when hovering
over the value in the socket.
* Only works for built-in nodes that already use the new node
declaration system. This can later be extended to support pynodes.
Those limitations are well worth it for now, given that the
implementation is quite simple and the impact on usability is quite
large. More complex updates to the layout system, that would allow
showing socket tooltips in the nodes, can be done later. With the
current implementation we can at least start writing tooltips for
geometry nodes now.
This commit already adds tooltips for the Cylinder node as an example.

When Browsing libraries the asset files were opened multiple times.
once to determine the needed groups to query and once for each

This implements the update logic for the vizualization of which
sockets pass data or constants directly, and which pass functions.
The socket shapes may still have to be updated. That should be
done separately, because it might be a bit more involved, because
socket shapes are currently linked to keyframe shapes. Currently
the circle and diamond shapes are used with the following meanings:
- Input Sockets:
- Circle: Required to be a single value.
- Diamond: This input supports fields.
- Output Sockets:
- Circle: This output is a single value.
- Diamond: This output may be a field.
Connecting a field to a circle input socket is an error, since a
field cannot be converted to a single value. If the socket shape
is a diamond with a dot in the middle, it means it is currently
a single value, but could be a field.
In addition to socket shapes, the intention is to draw node links
differently based on the field status. However, the exact method for
conveying that isn't decided yet.

This follows three main targets:
* Make creation of new tree UIs easy.
* Groundwork to generalize tree UIs (so e.g. Outliner, animation
channels, asset catalogs and spreadsheet data-sets don't have to
re-implement basic tree UI code) or even other data-view UIs.
* Better separate data and UI state. E.g. with this, tree-item selection
or the open/collapsed state can be stored on the UI level, rather than
in data. (Asset Catalogs need this, storing UI state info in them is
not an option.)
In addition, the design should be well testable and could even be
exposed to Python.
Note that things will likely change in master still. E.g. the actually
resulting UI isn't very nice visually yet.

Choosing a UV layer would actually affect the overlay in the viewport
and also painting with the mask brush was in that UV space, but the
resulting stencil mask was always applied with the active UV (not the
explicitly selected stencil UV -- the one one is looking at in the
viewport!) to painting.
This has been like that as far as I have checked back (at least 2.79b),
I am surprised this has not come up before, but it does not seem to make
sense at all...
Now use the UV specified for the stencil layer when applying the mask for
painting, so it corresponds to the stencil mask one is looking at in the
viewport.

Catalogs work like directories on disk (without hard-/symlinks), in that
an asset is only contained in one catalog.
See T90066 for design considerations.
#### Known Limitations
Only a single catalog definition file (CDF), is supported, at
`${ASSET_LIBRARY_ROOT}/blender_assets.cats.txt`. In the future this is
to be expanded to support arbitrary CDFs (like one per blend file, one
per subdirectory, etc.).
The current implementation is based on the asset browser, which in
practice means that the asset browser owns the `AssetCatalogService`
instance for the selected asset library. In the future these instances
will be accessible via a less UI-bound asset system.
The UI is still very rudimentary, only showing the catalog ID for the
currently selected asset. Most notably, the loaded catalogs are not
shown yet. The UI is being implemented and will be merged soon.
#### Catalog Identifiers
Catalogs are internally identified by UUID. In older designs this was a
human-readable name, which has the problem that it has to be kept in
sync with its semantics (so when renaming a catalog from X to Y, the
UUID can be kept the same).
Since UUIDs don't communicate any human-readable information, the
mapping from catalog UUID to its path (stored in the Catalog Definition
File, CDF) is critical for understanding which asset is stored in which
human-readable catalog. To make this less critical, and to allow manual
data reconstruction after a CDF is lost/corrupted, each catalog also has
a "simple name" that's stored along with the UUID. This is also stored
on each asset, next to the catalog UUID.
#### Writing to Disk
Before saving asset catalogs to disk, the to-be-overwritten file gets
inspected. Any new catalogs that are found thre are loaded to memory
before writing the catalogs back to disk:
- Changed catalog path: in-memory data wins
- Catalogs deleted on disk: they are recreated based on in-memory data
- Catalogs deleted in memory: deleted on disk as well
- New catalogs on disk: are loaded and thus survive the overwriting
#### Tree Design
This implements the initial tree structure to load catalogs into. See
T90608, and the basic design in T90066.
