It's valid for a node group connected to the modifier not to
have a geometry input, but I didn't consider that case
with the last change I made here, f3bdabbe24.
Differential Revision: https://developer.blender.org/D13231
The code assumed that any geometry input that wasn't the first input
was a second geometry input. Fix by separating the warning for the
first input and for the number of geometry inputs.
rBc473b2ce8bdbf8fa42 improved the situation somewhat, but
attribute search still crashes during animation playback, because
the UI search data references stale memory. The proper solution
is to allow the search to own data rather than just referencing it,
but I would prefer not to do that for 3.0. In the meantime, just
disable attribute search when animation is playing.

This commit adds modifier error messages to some of the cases
where the node group is configured improperly. It also clears the
geometry set when there is an error with the node group. This is
consistent to what we do in nodes themselves, and feels more
intuitive than passing the input geometry through the node group
silently.
Fixes T87142
Decorators were only added for the first item of an array.
Decorators for all items of an array are added:
- if the layout is flagged `UI_ITEM_PROP_DECORATE` automatically in
`uiItemFullR` or
- calling `uiItemDecoratorR` (but only in certain situations, see below)
When calling `uiItemDecoratorR` with an index of 0, the following
happens:
- the index is passed to `uiItemDecoratorR_prop`
- that checks with `ui_item_rna_is_expand` if decorators should be added
to all items of an array
- the check fails (because it only permits RNA_NO_INDEX -- which is -1)
So two things we can do:
- remain using `uiItemDecoratorR` (that would require to pass an index
of RNA_NO_INDEX -- a bad level include -- or -1
- just use `uiLayoutSetPropDecorate` to flag the row properly
This patch does later.

Reference struct members by name instead relying on their order.
This also simplifies moving back to named members when all compilers
we use support them.
During animation playback, data-blocks are reallocated, so storing
pointers to the resulting data is not okay. Instead, the data should
be retrieved from the context. This works when the applied search
item is the "dummy" item added for non-matches. However, it still
crashes for every other item, because the memory is owned by the
modifier value log, which has been freed by the time the exec function
runs.
The next part of the solution is to allow uiSearchItems
to own memory for the search items.
Cloth modifier had a unique, weird and weak way of copying its
pointcache, now make it use `BKE_ptcache_copy_list` like done for e.g.
particles or softbody data.
The geometry node evaluator now has access to the entire socket path
from the node that produces a value to the node that uses it. This allows
the evaluator to make decisions about at which points in the path the
value should be converted. Multiple conversions may be necessary under
some circumstances with nested node groups.

This is meant to add something to the sub-panel when it is empty
so it looks more purposeful, but also add a hint that might be helpful

Mantaflow could steal tasks from dependency graph, which under

Instance IDs serve no purpose for rendering when they aren't stable from
one frame to the next, and if the index is used in the end anyway, there
is no point in storing a vector of IDs and copying it around.
This commit exposes the `id` attribute on the instances component,
makes it optional-- only generated by default with the distribute points
on faces node.
Since the string to curves node only added the index as each instance's
ID, I removed it. This means that it would be necessary to add the ID
data manually if the initial index actually helps (when deleting only
certain characters, for example).

The leak happened when two things were true:
* Inside of a node group a socket is linked to a Group Input that has
a different type.
* The corresponding input on the parent Group node is not linked.
The conversion happened correctly, but the original value wasn't
destructed.
This adds attribute search to the geometry nodes modifier
for the input and output attributes. The "New" search item
is only shown for the output attributes.
Some of the attribute search code is extracted to a new file
in the interface code, to avoid some code duplication.
The UI code required two fixes so that the search would work
for dynamic length strings (IDProperties do not have a fixed size).
Since this does changes to the UI layout of the modifier, I also
addressed T91485 here.

There were some issues when multiple inputs of the same node
were forced to be computed (e.g. for the spreadsheet), but none
of the node outputs (if existant) were used. Essentially the node
was marked as "finished" too early in this case.
This fix is necessary for the improved viewer node (T92167).
In order to address feedback that the "Stable ID" was not easy enough
to use, remove the "Stable ID" output from the distribution node and
the input from the instance on points node. Instead, the nodes write
or read a builtin named attribute called `id`. In the future we may
add more attributes like `edge_id` and `face_id`.
The downside is that more behavior is invisible, which is les
expected now that most attributes are passed around with node links.
This behavior will have to be explained in the manual.
The random value node's "ID" input that had an implicit index input
is converted to a special implicit input that uses the `id` attribute
if possible, but otherwise defaults to the index. There is no way to
tell in the UI which it uses, except by knowing that rule and checking
in the spreadsheet for the id attribute.
Because it isn't always possible to create stable randomness, this
attribute does not always exist, and it will be possible to remove it
when we have the attribute remove node back, to improve performance.

This commit removes the implicit conversion from points to a mesh
that used to happen before the next modifier. It also removes the
implicit realizing of instances that happened before another modifier.
Now we have specific nodes for both of these operations, the
implicit conversions make less sense, and implicit instance
realizing has already been removed in other nodes.
This adds another geometry nodes modifier before modifiers that would
have realized instances implicitly before. Currently adding another
data-block during versioning after linking means that an assert needs
to be changed. That should be made unnecessary by T92333.

Previously, some multi-functions were allocated in a resource scope.
This was fine as long as the multi-functions were only needed during
the current evaluation of the node tree. However, now cases arise
that require the multi-functions to be alive after the modifier is finished.
For example, we want to evaluate fields created with geometry nodes
outside of geometry nodes.
To make this work, `std::shared_ptr` has to be used in a few more places.
Realistically, this shouldn't have a noticable impact on performance.
If this does become a bottleneck in the future, we can think about ways
to make this work without using `shared_ptr` for multi-functions that
are only used once.
Back in Blender 2.30, the GUI project brought panels into Blender among other important visual updates.
For the first time it was possible to move the wall of buttons around. Providing a clear separation
between sections (it even allowed the grouping of panels in tabs!)
During the 2.5 redesign, the separation between panels became a line on top of each panel, and panels received
theme settings for background and header colors. The default theme used the same color for both.
In 2.8 the background color of panels was different from headers in the default theme, so the separator
line was removed. While the separator line wasn't elegant (only on top, non-themeable, hard-coded emboss effect),
it provided a sort of separation between panels.
This patch solves the panels-separation by simply adding a margin space around them (not visible in default theme yet).
Even though the margin reduces the width of the working area slightly, it makes room for the upcoming always-visible scrollbars.
Other adjustments:
* Use arrow icon instead of triangle to collapse/expand
* Use rounded corners to match the rest of the UI (editor corners, nodes, etc).

Margin on panels makes use of the `style->panelouter` property that hasn't been
used in a while. Also slight tweaks to `boxspace` and `templatespace` style properties so they
are multiples of 2 and operations on them round better.
There is technically no need to update the themes for them to work, so no theme changes are included in this patch.

A new theme setting under Style controls the roundness of all panels (added it to Style instead of ThemeSpace because I think controlling the panel roundness per editor is a bit overkill):

Instead of checking whether the socket value was hidden, use the proper
node declaration to check whether the socket has an implicit input. The
remaining larger change to make is allowing nodes to specify what their
implicit input should actually be.
The sockets are not exposed in any nodes yet.
They work similar to the Object/Collection/Texture sockets,
which also just reference a data block.

attributes. Individual set nodes are used so that the values can be
exposed for direct editing, which is useful for attributes like shade
smooth and spline resolution. Individual input nodes are used to allow
reusing nodes for multiple components, and to allow grouping multiple
outputs conceptually in the same node in the future.

This enables fields as the official workflow for geometry nodes.
While many features are converted to use fields rather than the old
attribute workflow, many are not yet converted. In that case, the
unconverted nodes are still accessible with an experimental option.
In the coming weeks the rest of the nodes will be converted.
