The `TD_NOTCONNECTED` flag is not set in all cases.
In some cases, such as Meshes, the `FLT_MAX` value better determines
when the `TrasData` is not "connected".
Therefore, this commit removes the `TD_NOTCONNECTED` flag and adapts
the code to rely on the `FLT_MAX` value instead.
These TrasDatas shouldn't even be created in these cases.
Show node group inputs in the redo panel, including the
"use attribute" toggle. There are a few limitations that will
be solved separately:
- The redo panel is _always_ drawn, there is no way to show it conditionally yet
- There is no way to add the operator name to the redo panel title yet
- Attribute search is still missing for attribute inputs

Adds a new "Ui Asset Shelf" template to the script editor, demonstrating
how scripts can register own asset shelves. The asset shelf is designed
as a new standard UI element that add-ons, application templates and the
like can use, so this is useful. It's also useful as a quick way to test
and customize the asset shelf.
The script is only available in the UI if the "Asset Shelf" experimental
feature is enabled in the Preferences.
With the "Extended Asset Browser" and "Asset Shelf" experimental
features enabled, an asset shelf will now be displayed in sculpt mode.
This is useful for testing and development for the brush assets project,
see #101895.
Approved as part of #104831, then split off as separate commit.
Remove the "_for_read" suffix from methods to get geometry and geometry
components. That should be considered the default, so the suffix just
adds unnecessary text. This is consistent with the attribute API and
various implicit sharing data access methods.
Use "from_mesh" instead of "create_with_mesh". This is consistent with
the recently used naming for the `IndexMask` API.

` RenderData::border` and `View3d::render_border` are independent of each other.
Render region can be enabled even if the `V3D_RENDER_BORDER` flag is disabled.
And using the viewport render border shouldn't disable the camera view outer borders.

The previous commit introduced all the basic bits and pieces necessary
to support asset shelves as experimental feature, but didn't actually
add support for any specific editor. With this commit asset shelves can
be registered in 3D Views, which should soon be used by the Pose Library
add-on to replace its previous UI in the sidebar (see
blender/blender-addons#104546). Note that until then, there will still be no
actual asset shelf to display.
Also adds:
- Toggle to hide/unhide the asset shelf under "View" -> "Asset Shelf"
- 3D View theme settings for the asset shelf regions.
None of the changes are visible if the experimental option for the asset
shelf is not enabled.
Approved as part of #104831, then split off as separate commit.

No user visible changes expected, except of new experimental feature
option.
------------------------------------------------------------------------------
This introduces asset shelves as a new standard UI element for accessing
assets. Based on the current context (like the active mode and/or tool), they
can provide assets for specific workflows/tasks. As such they are more limited
in functionality than the asset browser, but a lot more efficient for certain
tasks.
The asset shelf is developed as part of the brush assets project (see #101895),
but is also meant to replace the current pose library UI.
Support for asset shelves can quite easily be added to different editor types,
the following commit will add support for the 3D View. If an editor type
supports asset shelves, add-ons can chose to register an asset shelf type for
an editor with just a few lines of Python.
It should be possible to entirely remove `UILayout.asset_view_template()` once
asset shelves are non-experimental.
Some changes are to be expected still, see #107881.

"Tool" is a more friendly word with mostly the same meaning within
Blender. Eventually it should be possible to create active tools with
node groups anyway, so the distinction isn't even helpful.

Implement capture point bias. This offsets the capture
points to reduce the amount bad capture locations (i.e.:
inside objects, near walls etc...).
Two new parameters are added:
- Capture Surface Bias: Ensure a minimum distance between
capture points and surrounding geometry. This is expressed as the
relative distance between two capture point. Requires re-bake
to take effect.
- Capture Escape Bias: Moves capture points enclosed inside
objects above the nearest surface. This bias defines how far a
capture point can be moved for escaping the object. This is
expressed as the relative distance between two capture point.
Requires re-bake to take effect.
This is called virtual offset in the reference material.
A quick prepass runs before the baking to offset the samples away
from any surface that could potentially make bad samples.
In order to speedup the process, we create cluster list of surfels
near each irradiance grid point. This allow access to neighboring
surfels that can contribute to the virtual offset which should
never be more than half a cell wide.

A few places already calculated vertex normals with better contextual
information to improve performance. To allow changing the storage of
vertex normals more (mostly for improved caching), change some code
from "get normals, set values, clear dirty flag" to "make vertex
normals data, give to mesh". This makes the API less awkward too,
since previously the "get for write" and "clear dirty" calls always
had to be separated.

Implement invalid sample points filling. Improves invalid regions
but introduce light leak.
Grid sample points are considered invalid if they have a ratio of
front-face ray hit under the given threshold. This is a post-processing
pass on the baked lighting that fills dark regions produced by
invalid sample location (e.g.: inside walls) with valid neighbor
samples data.
Two new parameters are added:
- Dilation Threshold: Validity threshold under which grid samples are
considered invalid. Invalid samples will gather valid lighting data
from valid neighbors inside the dilation radius.
- Dilation Radius: Radius of the dilation process. Expressed in grid
sample distance.
The validity of each point is progressively refined just like the
lighting data during the baking process.
The dilation process is implemented as a post-processing pass during
the loading of the grid data into the irradiance atlas. This allows
live tweaking the dilation parameters.

This is a full rewrite of the raytracing denoise pipeline. It uses the
same principle as before but now uses compute shaders for every stages
and a tile base approach. More aggressive filtering is needed since we
are moving towards having no prefiltered screen radiance buffer. Thus
we introduce a temporal denoise and a bilateral denoise stage to the
denoising. These are optionnal and can be disabled.
Note that this patch does not include any tracing part and only samples
the reflection probes. It is focused on denoising only. Tracing will
come in another PR.
The motivation for this is that having hardware raytracing support
means we can't prefilter the radiance in screen space so we have to
have better denoising. Also this means we can have better surface
appearance with support for other BxDF model than GGX. Also GGX support
is improved.
Technically, the new denoising fixes some implementation mistake the
old pipeline did. It separates all 3 stages (spatial, temporal,
bilateral) and use random sampling for all stages hoping to create
a noisy enough (but still stable) output so that the TAA soaks the
remaining noise. However that's not always the case. Depending on the
nature of the scene, the input can be very high frequency and might
create lots of flickering. That why another solution needs to be found
for the higher roughness material as denoising them becomes expensive
and low quality.

Recently a user expressed interest in exporting baked animation
with B-Bone segments. Currently the python API already exposes
segment matrices via a PoseBone method, but there is no access
to the mapping of vertices to the segments.
Although currently the math is simple and easy to re-implement,
forcing Python add-ons to do that would cause a maintenance issue
if the mapping is ever changed later (it's quite dumb, ignoring
the rest pose curve, and there definitely is room for improvement).
This patch extracts the relevant math into a BKE function, and
exposes it in the python API as a new PoseBone method.

In current blender, when drawing curves in the Graph Editor,
it always iterates over the whole curve.
From first to last vertex no matter what is shown on screen.
Instead of that, find the bounding keyframes and iterate within them.
Additionally to that, break apart the logic into two sections
* first iterate over keyframes and add `float2` into a `Vector`
* then iterate over all those points and draw them
The second optimization is to make the Bezier resolution
dependent on the keyframe distance in screenspace.
Previously it just went off the distance between keys in frames,
but that doesn't make sense if you are zoomed out.
## Performance Numbers
The following performance numbers are the
average time **per curve** on a mocap file of 6000f (each frame has a key).
The numbers were generated **without** showing keyframes to only focus
on the performance of this patch.
Also they are from a debug build, so they just make sense relative to each other
| - | before | after |
| - | - | - |
| zoomed in | ~1000μs | ~77μs |
| zoomed out | ~1000μs | ~430μs |
This only affects the actual curves.
Keyframe and handle drawing can likely still be improved

`NLASTRIP_TYPE_TRANSITION` was being used incorrectly as a flag, having
`NLASTRIP_TYPE_TRANSITION=1` and `NLASTRIP_TYPE_SOUND=3` in the enum
`eNlaStrip_Type`, when evaluating `NLASTRIP_TYPE_SOUND &
NLASTRIP_TYPE_TRANSITION` gives a invalid truish value.
Also `strips` that can't be placed were freed, but no removed from the
`strips list`, this will cause a error if the `strip` is at begin
or end of the list.

The property label on the Timeline for showing only channels
from selected objects was wrong,
indicating it shows only keyframes from selected channels.
This fixes it by using the same label and description as the dope sheet uses.

Instead of using pointers for these functions, they should be using
references (in most cases) and let the caller make sure that the
layer actually exists.
There were two separate issues occurring here:
With some other recent changes to curve handles, an early exit was
added when the handles should not display, however, this early exit
was not discarding geometry in the Metal implentation, but leaving
values undefined. Resulting in random geometry flickering on screen.
This may not previously have happened in certain modes if the vertex
buffers were zero-initialised up-front (which only happens with certain
debug flags).
Curve handle geometry generation would render incorrectly when
outputting triangleStrips IF the transparent border was disabled.

In `Layer::remove_frame` there is a case where the frame is not removed,
but overridden by a null-frame. In this case, the frames map was not
tagged, when it should have been.
Changing the frames map would lead to a crash later in undo.
This was because the `frames_storage` was not written to file corectly.
When the `frames_storage` was tagged dirty, it recreated the
`frames_storage.num` as well as the `keys` and `values` pointers.
The `keys` and `values` pointers were written after the update, but
since the `num` is just an `int` in the embeded struct, it was written
before being updated. This lead to an out-of-sync state and later
to the crash.
The fix makes sure we write the struct *after* updating it.
