Fixed layout widths would previously be ignored, resulting in incorrectly sized
grid view items. This is especially relevant for displaying grid views in
popups, where these fixed width are commonly used.
Necessary for the brush assets project which adds a popup version of the asset
shelf, see #116337.
This adds a new `Axes to Rotation` node which creates a new rotation.
In many cases, the primary and secondary axis inputs are a normal and
tangent of a mesh or curve. This provides a simpler and more direct way
to create this rotation compared to using two `Align Rotation to Vector` nodes.
This more direct way of computing the rotation also allows us to optimize
the case better.
The node rotates one axis (X, Y or Z) to the given primary axis direction. Then
it rotates around that primary direction to align the second axis to the given
secondary direction. Ideally, both input axes are orthogonal. However, the node
still creates the "best" rotation when they are not orthogonal. If one or the axes
is zero or both are (close to) parallel, the resulting rotation is unstable. There is
not too much the node can do to make it more stable.

The optimization to only add grid view items to the layout that are actually in
view relied on View2D information on scrolling. Popups don't use View2D, so
with this change the optimization will be skipped when View2D is not used.

Fix#120566 case.
Moved initial `lod_bias` calculations from `Light` struct to
`ShadowDirectional` and `ShadowPunctual` classes to avoid value
runaway during subsequent syncs. Changed internal functions to
use member variable instead of parameters.

As part of #121565.
To avoid using drawing indices outside of the internal grease pencil API,
this refactor adds the functions `GreasePencil::get_eval_drawing` to replace
the `get_eval_grease_pencil_layer_drawing*` functions.

This allows node groups to have a description that is shown in the add menu
or when hovering over the node header.
This new description is stored in `bNodeTree.description`. Unfortunately, it
conflicts a bit with `ID.asset_data.description`. The difference is that the latter
only exists for assets. However, it makes sense for node groups to have
descriptions even if they are not assets (just like `static` functions in C++ should
also be able to have comments). In some cases, node groups are also generated
by addons for a specific purpose. Those should still have a description without
being reusable to make it easier to understand for users.
The solution here is to use the asset description if the node group is an asset,
and to use `bNodeTree.description` otherwise. The description is synced
automatically when marking or clearing assets.
A side benefit of this solution is that appended node group assets can keep their
description, which is currently always lost.

Text strips in VSE got:
- Configurable shadow angle and offset (previously shadow location relative to
text was fixed). Currently the shadow position is rounded to integer pixel
locations; sub-pixel positioning might come later.
- Optional shadow blur amount.
- Optional outline, with color and outline width controls. Outline is
implemented using jump flooding algorithm.

This (experimental, for now) node retrieve's voxel values
at specific voxel indices for a grid input. It's similar to the
Sample Grid node (77cba3d551), but there is
no interpolation, and it uses indices instead of positions.

The node uses multiple transform operations, each using its own sampling. Using bicubic sampling in the translate node causes undesired offsets.
These changes were intentional (see test updates in `c4e1be73`), but the offsets were thought to be too small for users to notice.

Skip modifier, when using strip as a mask that ends before specified
timeline frame. To make behavior of missing mask more consistent,
modifier is also skipped, when strip produces blank output due to
missing data.
Skipping modifier due strip boundary only works, when "Mask Time" is set
to Relative mode. This is because absolute mode ignores strip offsets.

Was caused by float imprecision and storage precision
conversion. Use same fix as combined pass but
more selective as the alpha channel can contain
other data for AOVs.
Fix#118494
Previously in
```
edge_y = edge_step(current_vertex_y, edge_y, ¤t_vertex_y);
while (!BM_elem_flag_test(current_vertex_y, BM_ELEM_TAG))
```
With hidden faces this code enters in an infinite loop by returning the same null
edge in edge_step() and the same current_vertex_y causing Blender to crash.
The current fix solves the infinite loop and provides a solution when faces are hidden.
This causes the hidden faces to be merged into one for unsubdivided per original dev's implementation.
At minimum the crash is identified and a solution proposed.
Attached is a video of the fix

Added `BLENDER_EEVEE_NEXT` engine ID to polling code called during
"drag search". Main ADD menu routines already had this ID.
Fixes#121026 missing `Shader to RGB` node.
`Specular BSDF` node had similar problem, fixed as well.

An earlier commit accidentally removed too much code. This is now
restored, so that when keyframe insertion fails, at least on stdout it's
logged which F-Curve caused this failure.
8dbd167e80 did improve the error
reporting, but even that does not explicitly mention which F-Curves
caused those errors (for good reason, as cluttering the UI would be very
simple then).

This affects only transparent materials. Ideally, the shader
compilation should trigger a tag update on the object but
that's bad level call.
Instead, we just discard all shadows after finishing recompiling
a transparent material. This is overly conservative but it fixes
the issue.
Fixes#119624
Displaying an operator in the context menu that would access the asset
via context would fail.
3 issues here in fact:
- 798219225d removed code to attach the asset to the button's context.
Brought this back.
- If the `AssetShelf.get_active_asset()` method (in Python) isn't set,
`AssetViewItem::should_be_active()` would always return false, making
it impossible to lookup the active item. Instead it should return an
empty value so the view's internal active state is used instead.
Mistake in a700c90ec3.
- These kind of context queries can't rely on cursor coordinates, it's
not well defined what state they are in. In fact `wmWindow.eventstate`
is unset in debug builds to help enforce this. Also an issue from
a700c90ec3. With the above two corrections this change can be
undone so the query doesn't depend on cursor coordinates anymore.
This is caused by #121137 as the bug disappear if
`can_use_default_cb` returns false.
The issue is caused by the material binning system.
`ShaderKey` uses the `GPUMaterial` to differentiate between
material. But with #121137, different materials can reuse the
same `GPUMaterial`.
The fix is to not reuse the shader for the prepass (even if opaque)
for transmission enabled shaders.
Fix#121343
This parameter was introduced to mitigate shadow tracing
artifacts. These are no longer present since #121317 and
leaving this parameter breaks PBR rules which opens other
issues with shadow disconnected from shading.
Due to recent changes geometry without any vertices could lead to
a division by zero when copying motion vectors.
This PR fixes this by skipping the copy step when there are no
vertices to copy.

Caused by 598af45459
Above commit added respect for the NLA strip offset (rightfully so, by
using `ANIM_nla_mapping_apply_fcurve`).
However, when no closest frame was found, the code moved on to the next
FCurve without restoring to the original FCurve --
`ANIM_nla_mapping_apply_fcurve` needs to be called in pairs.
To resolve, now always restore to the original FCurve.

This changes the following keyframing functions to return
`SingleKeyingResult`, which is in turn used for better failure
reporting in the higher-level functions that call them:
- `KeyframeStrip::keyframe_insert()`
- `insert_vert_fcurve()`
As a side effect, this also means that
`rna_KeyframeAnimationStrip_key_insert()` can no longer return an
`FCurve *`, and now instead returns a bool indicating success.
This is part of an ongoing progressive refactor to improve error
messages and failure handling in the keyingframing code.

The goal of this PR is to remove the per face, NDC space
tracing for shadow maps.
This requires custom occluder extrapolation but in return
removes quite a lot of complexity in other areas, namely:
- No more per face transform before the tracing
- No more per face jittering (fix#119565)
- No more frustum padding (increased maximum precision)
- Better use of 32bit precision shadow map
- Fix#121343
This improve softness at relatively low step count (default 6
is better) and reduces light leaking at very low sample
count (sharper). It makes it more intuitive now that
higher sample count is smoother.

For metric units the depth was being rounded to the nearest meter
(in the range of 10-100 meters), increase the precision from 2 to 4
so it's possible to see centimeter precision.
BKE_mesh_validate is called by mesh.validate() Python API, as well as optionally
when doing file imports. This PR speeds it up a bit:
- Faster face data sorting by using parallel sort instead of qsort,
- One allocation for all face vertex indices, instead of a separate allocation
for each face,
- (more like a fix) Validation no longer adds a MDeformVert layer when there was
none in the input mesh.
- Small cleanups (more const inputs, etc.)
On my Windows/VS2022/Ryzen5950X machine, import time in seconds (validation on
before this PR -> validation on with this PR, validation off):
- USD (Intel Moore Lane): 9.1 -> 6.7, 4.8.
- OBJ (Blender 3.0 splash): 22.7 -> 18.6, 16.5.

This adds the same overlay that already exists for the bake node to the simulation output node.

Bezier handles are recalculated in many places in the
animation code. Threading that code can give a performance
boost all over Blender.
This patch only threads a part of the handle calculation code.
`BKE_nurb_handle_smooth_fcurve` can still be run in parallel,
but that's more complicated, so not done in this PR.
Overall this patch mostly benefits code paths that are not already threaded.
