From the user perspective, the transform tools in editmode and
sculptmode look like the same tools, the equal behavior could be
expected.
So now set vertices on the mirror axis (check with the same epsilon as
editmode transform) while transforming, replicating what
`mesh_transdata_mirror_apply` does.

While the evaluated result is not well defined, we expect Blender to not crash
when there are dependency cycles.
The evaluation of one object often takes the evaluated geometry of another
object into account. This works fine if the other object is already fully
evaluated. However, if there is a dependency cycle, the other object may not be
evaluated already. Currently, we have no way to check for this and were mostly
just relying on luck that the other objects geometry is in some valid state
(even if it's not the fully evaluated geometry).
This patch adds the ability to explicitly check if an objects geometry is fully
evaluated already, so that it can be accessed by other objects. If there are not
dependency cycles, this should always be true. If not, it may be false
sometimes, and in this case the other objects geometry should be ignored. The
same also applies to the object transforms and the geometry of a collection.
For that, new functions are added in `DEG_depsgraph_query.hh`. Those should be
used whenever accessing another objects or collections object during depsgraph
evaluation. More similar functions may be added in the future.
```
bool DEG_object_geometry_is_evaluated(const Object &object);
bool DEG_object_transform_is_evaluated(const Object &object);
bool DEG_collection_geometry_is_evaluated(const Collection &collection);
```
To determine if the these components are fully evaluated, a reference to the
corresponding depsgraph is needed. A possible solution to that is to pass the
depsgraph through the call stack to these functions. While possible, there are a
couple of annoyances. For one, the parameter would need to be added in many new
places. I don't have an exact number, but it's like 50 or so. Another
complication is that under some circumstances, multiple depsgraphs may have to
be passed around, for example when evaluating node tools (also see
`GeoNodesOperatorDepsgraphs`).
To simplify the patch and other code in the future, a different route is taken
where the depsgraph pointer is added to `ID_Runtime`, making it readily
accessible similar to the `ID.orig_id`. The depsgraph pointer is set in the same
place where the `orig_id` is set.
As a nice side benefit, this also improves the situation in simple cases like
having two cubes with a boolean modifier and they union each other.

During the strips redesign it was tested to go with drop shadows but
in practice and based on user feedback it looks better without.
- Remove drop shadow.
- Use white text for active/selected strips, black for unselected.

EEVEE stores light probes using octahedral mapping. Compared to the previous
cubemap storage octahedral has less pixels. The 64x64 is becoming useless
and can be removed. This PR also enables generating light probe maps upto 4k.
Some issues were found: the offset of the sphere inside the atlas
was always set to mipmap level 0 offset. This was hidden because of the texture
wrapping. Also the offset was substracted from the local texture
coordinate when calculating the direction of the pixel. Might be that due
to the incorrect offset (mipmap level 0), the latter issue was never detected.
Pull Request: https://projects.blender.org/blender/blender/pulls/123074
The offset was only 0.5 which centered the gather
sample exactly on the first pixel of the quad.
With floating point arithmetic differences on Nvidia
this lead to the wrong set of texture pixel being
fetched by gather.
Using the coordinate at the center of the quad fixes
the issue.
Fix#123262
With selected strips, it is not clear where one of them begins and another
ends since their outlines are right next to each other.
This changes strip look so that:
- All strips have consistent dark 1pt outline at the outer edge.
- Selected strips have 2pt highlight inside said outer edge.
- Selected strips also have a 1pt wide 33% opacity darker line inside the
selection highlight (and inside possible handles). To improve readability
in case strip content happens to be similar to selection/active color.

Add-ons may attempt to load the GPU module in background mode when no GPU
context has been initialized yet. This would give an error on import.
If then later the GPU context does get initialized, for example for a
render engine, import would still fail as the module is cached.
This reverts commit d7f124f06f, and again
throws errors in methods and constructors instead of module import.

This fixes#121695. `float4x4` matrices are generally expected to be 16 byte aligned.
Currently, there is no mechanism (afaik) that allows allocating these overaligned types
when loading files from disk. This patch adds an array with alignment information for
each type in `SDNA`. Currently, the alignment is just `__STDCPP_DEFAULT_NEW_ALIGNMENT__`
for all types and is manually set for the `mat4x4f` DNA type. The .blend file format is
not changed at all. The alignment information is purely runtime data.
In the future it would probably be good to generalize this a bit more instead of
hardcoding the alignment for `mat4x4f`, but would make it unnecessarily complex for
now because this is intended for the release branch.

Current look of VSE timeline view strip transformation handles makes them
somewhat "too narrow", especially after recent changes that made them
more narrow than before (handle tweaking feature) and a strip visual change
that made strip outline not go outside of strip bounds. They are now just
2px wide, effectively.
This changes their look as outlined in #123332 design task:
- The inset dark line is no longer over the handles, but rather "inside"
of them (except when handles are semitransparent, i.e. for strips that
are not selected).
- The handles themselves have rounded corners.

Timeline markers get a default name of "F_<frame>" when creating with
`marker.add`, but an empty name with `marker.camera_bind`.
Because the name of the current frame's marker is displayed in the
viewport statistics, such markers appear as "<>" after the name of the
active object, which is confusing.
This change gives the same default name of "F_<frame>" to markers
created this way.
It also cleans up a comment in the line copied from, as that line was
introduced in late 2008 so probably not so temporary.

Now the `uiBlock` array for node is indexed with `node.index()` instead
of the draw-index which is not as readily available in some cases.
The main alternative would be to create an extra map from node index
to draw-index but that doesn't seem worth it right now.
Now the strip outline (1 point for unselected strips, 2 point outline +
1 pt dark inset) takes monitor DPI / user preference line width into
account, via the usual U.pixelsize machinery.

This was a missing block of the TAA implementation.
TAA jitter and reprojection have a tedency to soften
the texture. Add a 1.5 bias to make them a bit sharper.
Note that this is a bit different than the usual TAA
blurring. In final render we don't do reprojection
so it is only because the texture filter (box filter
from the LOD) is applied at the same time than our pixel
filter (blackmann-harris). It is less noticeable than
the normal TAA blur, but still blurs ~2px instead of
1.5px.
This adds a "Legacy Behavior" option to the Limit Rotation constraint that makes
it behave how Limit Rotation constraints did prior to
ed2408400d. Newly created constraints have this
option disabled, but versioning code enables the option on constraints from
older files to ensure that the behavior of e.g. existing rigs is not altered.
This is one part of a two-part fix for #123105. The other part is in PR
extensions/rigify#4.

`GpencilIOParams.ob` is set to `CTX_data_active_object` at the beginning
of the export [which is not ensured to be a valid `OB_GPENCIL_LEGACY`
object, non-valid objects are filtered out later in
`create_object_list`]. From this (potential non-greasepencil) object's
data, a "global `bGPdata` is stored in `GpencilIOParams`.
From here, it can only go downwards as `stroke_point_radius_get`,
`export_stroke_to_polyline`, `BKE_gpencil_stroke_perimeter_from_view`
all use this "global" `bGPdata`.
Two possible solutions might exist:
- [1] just cancel the operator if the active object is not a
`OB_GPENCIL_LEGACY` object
- [2] make sure we use corresponding `bGPdata` when iterating over
valid objects to export
This PR chooses [2] since it also seems wrong to always use the
`bGPdata` from the active object for certain calculations when iterating
many objects. For example, the export ignores different values for
`Thickness Scale` on different objects and always takes the value from
the active object, which does not seem to be by design.
NOTE: this changes behavior (see above) but for the better

When snapping keyframes in the Graph Editor, handles
that were set to free didn't move.
The issue was that the snapping code didn't set the handle position.
Instead it relied on the handle recalculation (`calchandleNurb_intern`) to do the job.
That code doesn't affect free handles though.
The fix is to also offset the handles in the snapping code. The handle recalculation
will still run for all the other handle types so that behavior isn't expected to change.
This does NOT change the behavior of bezier snapping in the 3D viewport.

This implement the holdout flag by switching to
the holdout case in the shader. This has a few benefits:
- Doesn't recompile the shaders.
- Makes the object infos mandatory (already the case in
practice)
- Handle transparent materials properly, keeping the
transparency working.

This happened in the following render test:
`render/light/all_light_types_in_volume.blend`
Unfortunately it seems non-deterministic.
To fix this, we change the heuristic to jump
out of the shadow update loop. Also introduce
a upper bound to the number of iteration.
On top of this, add a flush for every loop
to avoid huge command buffer submission.
Thanks @pragma37 for the fix.
This PR modifies the check for visibility when selected in the outliner.
With the change the visibility check only affects the selection state, not the active state.
The check has also been swapped with a function call to `ANIM_bone_is_visible_editbone`,
so now correctly works with collection visibility.
This PR also fixes the same issue for `Bone` and `bPoseChannel`

At high light count, this missing barriers would
produce invalid, non-unique `prefix_sum` indices.
This then resulted in some slots inside `out_light_buf`
never written to, leaving undefined data inside them.
If the buffer was cleared to zero, these undefined light
slots would be interpreted as sun lights and the
shadow setup compute pass would critically fail because
of out of bound memory.

EEVEE Film accumulation workaround for Metal/Intel iGPUs.
On Metal the Intel iGPUs do not support image read write
on array textures. However this limitation doesn't show
any artifacts when using the compute shader.
This PR is a work around that uses the film_comp shader
to process the film samples, but uses a separate film_copy_frag
shader to read the result and copy them to the frame buffer.
I deliberately didn't include the fix to the film_frag shader
as that would change the read/write resources and could lead
to performance issues for other platforms. Writable resources
are typically slower compared to read only resources.
Some code needed to be duplicated (and not added to `*_lib.glsl`)
as compilers would still raise compilation errors due to imageStore/Load
on incompatible resource access.
The Metal/Intel iGPU is also marked to have limited support as
raytracing and probes still produces big artifacts.
This workaround can be tested on any platform just by setting
`use_compute_ = true` in `Film::sync`

The previous code was using matrix multiplication to
get the local thickness to world thickness.
The correct way is to multiply the local thickness
by the scale of the object (length of each columns
of the object_to_world matrix).
