I had done some experiments to see what Fast boolean did for material
mapping and thought it just used the same slot in the target as the
slot in the source. The truth is more complicated: if the target material
exists in any slot of the destination, we need to remap to whatever
slot has the matching material. I fixed Exact Boolean to do this.
Since the materials may be in the object, this means that BKE_mesh_boolean
had to get another argument, the remapping arrays.
I will note that the current behavior of Fast, and now Exact, is not ideal.
Ideally, if the source material does not exist in the target, a new material
slot should be created in the target and the source material copied there
(and incrementing the material's reference count). Maybe a future project,
but for now, I want the behavior of Exact to match that of Fast.
Accumulate error caused by the low amount of integration slices and
correct it for the low roughness surfaces.
This increases light leak but it is less distracting than dark fringe
everywhere.
A block of code ran when `wm_keymap_update_flag` was non-zero,
replace this with explicit flag check since it wasn't
immediately obvious which flag needed to be set.
While this still isn't done by default on startup,
activating a key-config will load it as expected.
Needed to perform key-map loading tests in background mode.
This is necessary to make float sockets display a value with the unit
system. `PROP_DISTANCE` will be used quite a lot by the mesh primitives
geometry nodes patch.

The shader was not using the horizon texture and was trying to
trace the AO again.
Also the depth reconstruction was off because now using the maxzBuffer.
This happens when the normal is too much deformed to give valid
reflection even after ensure_valid_reflection.
Cycles seems to not handle this case either so we just discard the
rays.
Simple divide by 0 error. The input radius was assumed to be safe
but is not when the user can scale it arbitrarly.
This also move the division out of the loop.
We now reuse 9 hitpoints from the neighboorhood using a blue noise
sample distribution as mentionned in the reference presentation.
Reusing more rays does however make some area a bit more blury.
The resulting noise is quite lower compared to previous implementation
which was only reusing 4 hits.
This make sure the rays are generated randomly from a fullres
texel center.
This creates more noise but increase the convergence when doing
half res tracing.
This split is to make code easier to manage and rename the files to
`effect_reflection_*` to avoid confusion.
Also this cleans up a bit of the branching mess in the trace shader.
This commit adds a `normal` attribute on the polygon domain. Since
normal data is derived data purely based off of the location of each
face's vertices, it is exposed as a read-only attribute. After
rB80f7f1070f17, this attribute can be interpolated to the other domains.
Since this attribute is a special case compared to the others, the
implementation subclasses `BuiltinAttributeProvider`. It's possible
there is a better way to abstract this. Something else might also
become apparent if we add similar read-only attributes.
See rB2966871a7a891bf36 for why this is preferred over the previous
implementation.

After further thought, the implementation of the "normal" attribute
from D10541 is not the best approach to expose this data, mainly
because it blindly copied existing design rather than using the
best method in the context of the generalized attribute system.
In Blender, vertex normals are simply a cache of the average normals
from the surrounding / connected faces. Because we have automatic
interpolation between domains already, we don't need a special
`vertex_normal` attribute for this case, we can just let the
generalized interpolation do the hard work where necessary,
simplifying the set of built-in attributes to only include the
`normal` attribute from faces.
The fact that vertex normals are just a cache also raised another
issue, because the cache could be dirty, so mutex locks were
necessary to calculate normals. That isn't necessarily a problem,
but it's nice to avoid where possible.
Another downside of the current attribute naming is that after the
point distribute node there would be two normal attributes.
This commit reverts the `vertex_normal` attribute so that
it can be replaced by the implementation in D10677.

The Attribute Convert node provides functionality to change attributes
between different domains and data types. Before it was impossible to
write to a UV Map attribute with the attribute math nodes since they
did not output a 2D vector type. This makes it possible to
"convert into" a UV map attribute.
The data type conversion uses the implicit conversions provided by
`\nodes\intern\node_tree_multi_function.cc`.
The `Auto` domain mode chooses the domain based on the following rules:
1. If the result attribute already exists, use that domain.
2. If the result attribute doesn't exist, use the source attribute domain.
3. Otherwise use the default domain (points).
See {T85700}

The result value should be true if the input values are not zero.
Note that there is ongoing conversation about these conversions
in D10685. This is simply a fix though.
This operator initializes mask values for the entire mesh. It supports
different modes for initializing those values, and more will be added in
the future.
The initial version supports generating a random mask per vertex, Face
Sets or loose parts. These masks are useful for introducing variations
in the model using the filters (both shapes and colors).

Before only it was only possible interpolate frames of `Keyframe` type. Now all types except `Breakdown` can be used.
`Breakdown` cannot be used because it would be impossible interpolate two times because the extremes of the interpolation would change and the clean operator would not work.
Add new function `blo_bhead_is_id_valid_type()` to correctly check the
blend file block type.
File block type codes have four bytes, and two of those are only in use
when these blocks contain ID datablocks (like `"OB\0\0"`). However,
there are other types defined in `BLO_blend_defs.h` that have four
bytes, like `TEST`, `ENDB`, etc.
The function `BKE_idtype_idcode_is_valid(short idcode)` was used to
check for ID datablocks while reading a blend file. This only takes a
2-byte parameter, and thus its result is invalid for the 4-byte codes.
For `TEST` blocks, it would actually consider it a `TE` block, which is
a valid identifier for a Texture. This caused the heap buffer overflow,
as the datablock is not a valid ID, and thus the bytes that were
expected to form an ID name actually encode something completely
different.

Sculpt undo relied on having a mode-changing undo step to properly
apply changes.
However this isn't the case with startup files or when mixing
global undo steps with sculpt (see T82851, also fixed).
Undo stepping logic follows image_undosys_step_decode_undo.
This is basically done by ignoring override operations from old override
affecting ID pointer properties, when the new (destination) one is not
NULL.
Fix T86501: New object added to overridden collection doesn't show up in linking file on Resync.
This is more of a work-around actually, since there is no real way to
fix the issue in a fully automated and consistent way, it is caused by
older blender files being saved with 'broken' overrides.
WARNING: This cannot ensure that some purposedly edited/overridden ID
pointer properties won't be lost in the process.
Code would end up freeing some of the newly created overrides, which
were assigned to the matching linked ID's `newid` pointer, accessed
again further down the code.
Note that this is not a normal expected situation, and it won't give a
proper resync result anyway, but it might happen in some complicated
corner cases, and also quite often when dealing with older .blend files.
In some cases (advanced, low-level), we also want to remap pointers like
`ID.newid` or `ID.orig_id`.
Only known case currently is `id_delete`, to avoid leaving potential access to freed memory. See next commit and T86501.
Baking to Vertex Colors would always bake to sculpt vertex colors (if
such a layer is present) even if those are not enabled in the
experimental preferences. This would bake without an error but leave the
user without a result to look in the viewport.
Now check if sculpt vertex colors are enabled and only bake to them in
that case.
