Fixes issue where motion blur would not display for
certain objects intermittently due to uninitialized
parameters in the ObjectKey struct causing the
motion object map look-up to fail and for motion
parameters to be reset to default, disabling the
effect for the given objects.

- Only calculate the necessary normals based on smooth/flat/mixed shading
- Use cached face normals instead of computing them
- Use a `VectorSet` for deduplication instead of a `Map`
- Deduplicate vertex normals and store indices in separate loops
- Avoid unnecessary duplication of face normal indices
- Inline simple function for slicing index span
Export time (ms) of 1.8m vertex mesh:
| Normals Domain | Before | After |
| --------------- | ------ | ----- |
| Face (flat) | 559 | 469 |
| Vertex (smooth) | 659 | 466 |
| Corner (mixed) | 656 | 640 |
The change of using normals from different domains and using a
VectorSet for de-duplication change the order of normals in the OBJ
files. Other than that, the results should be unchanged.

A draw list bundles multiple draw commands for the same geometry
and sends the draw commands in a single command. This reduces
the overhead of pipeline checking, resource validation and can
keep the load higher on the gpu as more work needs to be done.
Previously the draw list didn't bundle any commands and would still
send each call separately to the GPU. This PR implements the bundling
of the commands.

This was the case for custom normals.
There was an optimization in 91b4f9f1f6 that was skipping computation of
existing normals if the Mix Factor in the UI was at 1.0 (under the
assumption that in this case no old normals would be needed.
Problem is that the resulting mix factor is the product of the Mix
Factor in the UI and the weights, so just doing the check as in the
culprit commit is not enough.
Need to consider if weights are used.

This is because the `NODE_OT_group_edit` operator reuses the last value
of the `Exit` property and once this is set it would always try to pop
(instead of push [which is what we want from the icon]) the nodegroup.
Callers of the operator set `Exit` explicitly elsewhere (just not
from node drawing -- where the way it is called [via a more general
callback] makes it difficult to set operator properties from there).
Solve by not saving the property for following usages (flag
`PROP_SKIP_SAVE`).
Fixes#117530.

By default, Color Palettes are only drawn in the UI in the context of
**painting**.
UI button code then tries to update an appropriate brush from edits to
the palette.
So a valid `Paint` and `Brush` were assumed. This is not a problem for
objectmode (because `BKE_paint_get_active_from_context` then defaults to
`ImagePaintSettings`'s `Paint`), but other modes dont guarantee this
(editmode only returns a valid `Paint` when uv sculpting).
In the report, a palette was created and displayed via python, making
changes in editmode would then crash.
Solve by checking we have a valid Paint in corresponding UI code to
begin with.

This adds a proper poll function to the `brush_stroke` operator.
Ensures that this operator is only used by tools that are brushes.
Also changes the poll for the drawing of the cursor to only run
with tools that are brushes.
This patch adds support for _Menu Switch_ nodes and enum definitions in
node trees more generally. The design is based on the outcome of the
[2022 Nodes Workshop](https://code.blender.org/2022/11/geometry-nodes-workshop-2022/#menu-switch).
The _Menu Switch_ node is an advanced version of the _Switch_ node which
has a customizable **menu input socket** instead of a simple boolean.
The _items_ of this menu are owned by the node itself. Each item has a
name and description and unique identifier that is used internally. A
menu _socket_ represents a concrete value out of the list of items.
To enable selection of an enum value for unconnected sockets the menu is
presented as a dropdown list like built-in enums. When the socket is
connected a shared pointer to the enum definition is propagated along
links and stored in socket default values. This allows node groups to
expose a menu from an internal menu switch as a parameter. The enum
definition is a runtime copy of the enum items in DNA that allows
sharing.
A menu socket can have multiple connections, which can lead to
ambiguity. If two or more different menu source nodes are connected to a
socket it gets marked as _undefined_. Any connection to an undefined
menu socket is invalid as a hint to users that there is a problem. A
warning/error is also shown on nodes with undefined menu sockets.
At runtime the value of a menu socket is the simple integer identifier.
This can also be a field in geometry nodes. The identifier is unique
within each enum definition, and it is persistent even when items are
added, removed, or changed. Changing the name of an item does not affect
the internal identifier, so users can rename enum items without breaking
existing input values. This also persists if, for example, a linked node
group is temporarily unavailable.

EEVEE uses an HiZ buffer. The size of the HiZ buffer is based on the render extent.
Probes assume that the render extent is always bigger than needed for rendering
probes. This assumption is incorrect.
Although this PR fixes this by allocating the required size, it is still renders with
artifacts. These artifacts originate from the lighting module and also needs to be
fixed.

Part of overall "improve filtering situation" (#116980) task:
Add "Cubic Mitchell" filtering option to VSE strips. This is a cubic (4x4)
filter that generally looks better than bilinear, while not blurring the image
as much as the Cubic BSpline filter that exists elsewhere within Blender. It is
also default in many other apps.
Rename the (very recently added) VSE Bicubic filter option to Cubic BSpline.

After removing a bone collection that was marked as 'solo', refresh
the armature's 'solo active' flag. The deleted bone collection might have
been the last solo'ed one.
Add the 'solo' flag to bone collections, effectively adding another
layer of visibility controls.
If there is _any_ bone collection with this flag enabled, only this
collection (and others with this flag enabled) will be visible.
In RNA, the following properties are exposed:
- `bone_collection.is_solo`: writable property to manage the solo flag.
- `armature.is_solo_active`: read-only property that is `True` when any
bone collection has `is_solo = True`.
The RNA property `bone_collection.is_visible_effectively` now also takes
the solo flag into account.
Pull Request: https://projects.blender.org/blender/blender/pulls/117414
Rename `BoneCollection::is_visible_effectively()` to
`is_visible_with_ancestors()`. Soon a "solo" flag will be introduced,
and the effective visibility of the bone collection will depend on that
too. This particular function doesn't take that into account, though,
and thus needs a rename.
Note that this does NOT rename the RNA property
`is_visible_effectively`. That will be updated when the "solo" flag is
introduced to also take that into account.
No functional changes.

There are many instances where customizing the header row is desired so
return both the header row layout and the main body layout.
For consistency and correctness, the arrow symbol and the is_open check
are always performed so callers only need to perform layout tasks.
The C++ side now receives a `PanelLayout` structure containing both:
```cpp
PanelLayout panel_layout = uiLayoutPanelWithHeader( ... );
uiItemL(panel_layout.header, ... );
if (panel_layout.body) {
...
}
```
And the Python side receives a tuple:
```python
header, body = layout.panel( ... )
header.label(...)
if body:
...
```
```python
import bpy
from bpy.props import BoolProperty
class LayoutDemoPanel(bpy.types.Panel):
bl_label = "Layout Panel Demo"
bl_idname = "SCENE_PT_layout_panel"
bl_space_type = 'PROPERTIES'
bl_region_type = 'WINDOW'
bl_context = "scene"
def draw(self, context):
layout = self.layout
scene = context.scene
layout.label(text="Basic Panels")
header, panel = layout.panel("my_panel_id", default_closed=True)
header.label(text="Hello World")
if panel:
panel.label(text="Success")
header, panel = layout.panel_prop(scene, "show_demo_panel")
header.label(text="My Panel")
if panel:
panel.prop(scene, "frame_start")
panel.prop(scene, "frame_end")
layout.label(text="Customized headers")
# Add a checkbox to the Panel header. text must be None for this panel
header, panel = layout.panel("my_panel_id-2", default_closed=True)
header.prop(scene, "use_checkmark", text="") # text must be empty for the checkbox
header.label(text="Checkmark at beginning")

For modification the important point is that to propagate changes to
other keys it's necessary to know what the changes are, which means
comparing the old an new values, so you can't modify shape key data
in place.
Remove the need for the `calc_vertex_coords` function by combining
the scale into the existing transform needed to export vertex positions
in global space. This simplifies code and may slightly improve performance
(I only observed a few percent difference in the positions export, which is
not a slower part of the export).
- Use Span where ownership is unnecessary
- Use Array when dynamic growth is unnecessary
- Use Vector in all other cases
Also remove unnecessary namespace specification.
Boolean ID property support was added in ef68a37e5d, but the JSON
serializer for ID properties was not updated for it. This would be a
forward compatibility issue, if future json files containing boolean
properties would be read with old versions. Such properties are added
in #106303, for example.
When a keying set is enabled and the keying set option
"Active Keying Set" was chosen from the menu, it would
give an error.
That is because the active keyingset uses a special
ID string (`"__ACTIVE__"`)
that doesn't actually exist as a keying set.
To fix it, explicitly check against that string and return
the active if encountered.

The CPU implementation had the following downsides:
- The kernels sizes below 3 did not make much sense, often leading
to a full white image.
- The way how the total number of pixels in the kernel was calculated
quite strangely.
From these points of view the GPU compositor behaves more user friendly.
There is a versioning code which lowers the kernel size, to match the
result prior to these tweaks.

There exist a bunch of "give me a (filtered) image pixel at this location"
functions, some with duplicated functionality, some with almost the same but
not quite, some that look similar but behave slightly differently, etc.
Some of them were in BLI, some were in ImBuf.
This commit tries to improve the situation by:
* Adding low level interpolation functions to `BLI_math_interp.hh`
- With documentation on their behavior,
- And with more unit tests.
* At `ImBuf` level, there are only convenience inline wrappers to the above BLI
functions (split off into a separate header `IMB_interp.hh`). However, since
these wrappers are inline, some things get a tiny bit faster as a side
effect. E.g. VSE image strip, scaling to 4K resolution (Windows/Ryzen5950X):
- Nearest filter: 2.33 -> 1.94ms
- Bilinear filter: 5.83 -> 5.69ms
- Subsampled3x3 filter: 28.6 -> 22.4ms
Details on the functions:
- All of them have `_byte` and `_fl` suffixes.
- They exist in 4-channel byte (uchar4) and float (float4), as well as
explicitly passed amount of channels for other float images.
- New functions in BLI `blender::math` namespace:
- `interpolate_nearest`
- `interpolate_bilinear`
- `interpolate_bilinear_wrap`. Note that unlike previous "wrap" function,
this one no longer requires the caller to do their own wrapping.
- `interpolate_cubic_bspline`. Previous similar function was called just
"bicubic" which could mean many different things.
- Same functions exist in `IMB_interp.hh`, they are just convenience that takes
ImBuf and uses data pointer, width, height from that.
Other bits:
- Renamed `mod_f_positive` to `floored_fmod` (better matches `safe_floored_modf`
and `floored_modulo` that exist elsewhere), made it branchless and added more
unit tests.
- `interpolate_bilinear_wrap_fl` no longer clamps result to 0..1 range. Instead,
moved the clamp to be outside of the call in `paint_image_proj.cc` and
`paint_utils.cc`. Though the need for clamping in there is also questionable.

This (likely copy-pasted) check to report either an unknown operator
type, or a known operator type missing its RNA struct definition, had a
reversed logic. It would report a 'missing srna' for unknown operator,
and vice-versa.
