The case when there were no material indices, multiple materials, and
the mesh used hiding wasn't handled after 55970fa367.
This is a simple parallel loop adding up the non-hidden triangles.
Previously, it was only possible to bake all simulations at once. This is great
for simple use-cases that, but in more complex setups one can have independent
simulations that should also be baked independently. This patch allows baking
individual simulation zones.
Furthermore, each simulation zone can now also have its own bake path and
simulation frame range. By default the simulation frame range is the scene frame
range, but it can also be customized on the scene or simulation zone level. The
bake path is generated based on the modifier bake path by default, but can be
set to another absolute or relative (to the .blend file) path.
The timeline drawing has been modified as well to be able to show more information
in the case when some simulations are baked and others are not. Instead of showing
a line for every simulation, it shows a condensed view of the important information
using at most two lines:
Is something baked? Is something valid or invalid? Also see #112232.

Hair and Curves need to call `DRW_curves_update` before
`geometry_steps_fill`, otherwise the copied geometry is just
uninitialized data.
However, doing so triggers an assertion:
> DRW_render_instance_buffer_finish had not been called before drawing.
This PR ports the `DRW_hair/curves_pos_buffer_get` functions to the new
`draw::Manager` API, so it can be called at any arbitrary point.
It also changes `VelocityModule::geometry_map` to use `uint64` keys
instead of `ID` pointers, since the same particle system can be used on
different objects and have multiple geometries.
Notes:
* The new functions are only used for
`VelocityModule::step_object_sync` on image renders. Using them
elsewhere would require modifying the old draw manager to do the
init/update/free setup.
* Only the compute shader version has been ported.

This changes the `action.frame_range` Python API to return an accurate
frame range for actions. Specifically, it was previously special-cased
to return a range with length 1 whenever the length was actually 0. This
led to a bizarre situation where a real frame range of `[0.0, 0.2]` would
return that range as-is, but a real frame range of `[0.0, 0.0]` would
instead return a range of `[0.0, 1.0]`.
The new behavior simply always returns the real frame range.
The reason for the previous behavior was obscure: the relevant code was
also used internally in Blender's NLA system, and returning a zero-length
range could result in NLA strips getting infinite scale. The code is now
separated out appropriately so that the NLA system still gets the
non-zero-length range, while the Python API for actions returns the real
range.

This PR fixes an issue with the NVIDIA 3000/4000 series cards. The cause
might be that when blending is turned off and the fragment output has an alpha
of 0.0 the fragment might be discarded. This is a guess of course.
By setting the Alpha to 1.0 for scopes and enabling alpha blending when
drawing the meta data text seems to fix the issue.

c6b553d57c added the bone collection in
outliner. However, there is change in tree element order when switched
between pose and edit/object mode. Because order of tree building is
`edit bones -> bone collection -> pose bones`
To keep tree structure consistent between different modes, first draw
pose bone and then the ebone/bone collection.

Draw the background of the asset shelf header fully transparent, with an opaque
background with rounded corners behind sections containing buttons. This
reduces the visual space consumed by the asset shelf, and makes the header
follow a tabbed folder metaphor better. Also, this works much better with our
click-through feature, where transparent parts of regions without buttons are
passed through the region under it (we might want to consider unifying code
here a bit).
The edge to drag for region resizing respects the transparent sections.
When there is little space between sections, the sections get merged so that
there are no small gaps in the bar.

Draw anim channel colors as a little rectangle in the channel list,
instead of taking over the entire channel name background. This keeps
the channel names readable, regardless of the channel colors.
Channel colors are typically set via the bone colors, and since those
are chosen for visual contrast in the 3D Viewport, they aren't
guaranteed to also be a suitable background color for the channel list.
Because of this, it's no longer used as such.
The channel 'data' background (i.e. the keyframe area) is now drawn with
a consistent color, and much more subtle.
This also enables the 'Channel Group Colors' setting in the preferences
by default, as it is now way less obnoxious and invasive.

It was already called that way in the UI, since it's referring to a
behavior, not a type. Update the code to match that. Note that this is
a BPY compatibility breaking change for 4.0.
Use of node group assets relies on a few properties written to asset
meta-data for proper filtering of assets in menus (add modifier menu,
node add menu, 3D view menus for tools). Currently these meta-data
properties are written when updating their source properties and when
saving the file. That means they *aren't* written when marking a group
as an asset, which is necessary because the meta-data doesn't exist
before when the group isn't an asset. Currently users have to save the
file to update menus in this case, which isn't intuitive.
As a fix, call the function to write the meta-data when marking a
data-block as an asset.

In Vulkan (and Metal) it is not possible to use a global as point
size. It needs to be set for each vertex when drawing points. Blender
has specialized shaders for that, but not all code respect those
shaders.
This PR will add an assert inside the vulkan backend when incorrect
usage of shaders are detected.

This makes the SSS processing more isolated to avoid

Also this allow more optimization using LDS.
The radiance buffer is created by a setup phase using
direct and indirect lighting.
Splitting this into its own compute pass also fixes

This was discussed in #112022 and on devtalk:
https://devtalk.blender.org/t/vertex-groups-generic-attributes-and-name-clashing/31073
While vertex groups with the same name as attributes should be avoided, since
it can cause ambiguities when using attributes, it's something we can handle
gracefully for now. Enforcing unique names for vertex groups resulted in breaking
other functionality under some circumstances.
This effectively reverts 12ef20990b, except for
the bug fix in `BKE_id_attribute_new`.
#112891 adds a warning to avoid make users aware of duplicate names so that they
can be avoided in practice.

Currently the iteration over a PBVH node's vertices retrieves mutable
access to the mask custom data layer. This isn't threadsafe, but it is
done in the multithreaded loops over all nodes.
In general, we need to be more careful and conservative about storage
of non-const pointers to mesh data. Ideally we would only have one
mutable reference to a resource at a time. And we should avoid doing
work like looking up custom data layers more than we need to.
To that end, make the pointer to the custom data layer used everywhere
const, and retrieve mutable access before parallel node iteration with
a specific function, and write to the mask data with that in mind.
This pushes us in the direction of sharing less code per PBVH type.
In my opinion that's a good thing, because we can actually optimize for
each type. For example, `write_mask_data` gives a picture of
how each of these hot loops could become much simpler.

Currently vertices are mapped to B-Bone segments without taking the
rest pose curve into account. This is very simple and fast, but causes
poor deformations in some cases where the rest curvature is significant,
e.g. mouth corners in the new Rigify face rig.
This patch implements a new mapping mode that addresses this problem.
The general idea is to do an orthogonal projection on the curve. However,
since there is no analytical solution for bezier curves, it uses the
segment approximation:
* First, boundaries between segments are used for a binary space
partitioning search to narrow down the mapping to one segment.
* Then, a position on the segment is chosen via linear
interpolation between the BSP planes.
* Finally, to remove the sharp discontinuity at the evolute surface
a smoothing pass is applied to the chosen position by blending to
reduce the slope around the planes previously used in the BSP search.
In order to make per-vertex processing faster, a new array with the
necessary vectors converted to the pose space, as well as some
precomputed coefficients, is built.
The new mode is implemented as a per-bone option in order to ensure
backward compatibility, and also because the new mode may not be
optimal for all cases due to the difference in performance, and
complications like the smoothed but still present mapping
discontinuities around the evolute surface.

When using menu search, each search item has multiple segments. In the UI,
we only highlight last section, which is the actual node/operator name. The
menu path is grayed out. It seems reasonable to give greater weight to the
words in the search item that are highlighted.

This avoid confusion outside of the shader node GLSL code.
The issue also is that Metal allow float to cast to bool
implicitly but this create a compilation error on
OpenGL.
Scenes that only uses a world probe would didn't work. Raytracing
would look for the closest light probe, didn't find any and shader
would use undefined behavior to sample in the reflectionProbes texture.
In some cases this resulted in correct results when the world was
located on layer 0 with subdivision 0. In any other case this would
sample incorrect incoming light what lead to black reflections.
This PR fixes this by returning the world probe when no nearest light
probe cound be found.

This adds a new entry to the split sum LUT to isolate
the effect of the F82 tint.
The application of the tint part is similar to cycles
and uses the same way for precomputing the `b` factor.
Results matches almost perfectly to the extent of the
split sum approximation.
Note that this removes the unused LTC MAG LUT for
EEVEE next to make space for the new table. It can still
be added back if needed.

Since the menus are defined in the header region, but the keymap is part
of the 3D view window region, we need to specify that when creating the
operator buttons.
Texture Atomics have been added in Metal 3.1
and enable the original implementations of
shadow update and irradiance cache baking.
However, a fallback solution will be
required for versions under macOS 14.0 utilising
buffer-backed textures instead.
This patch also includes a stub implementation if
building/running on older macOS versions which
provides locally-synchronized texture access in
place of atomics. This enables some effects to be
partially tested, and ensures non-guarded use
of imageAtomic functions does not result
in compilation failure.
