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.
This checks the generated key-map data matches the result of
re-exporting and re-importing.
This shows up various inconsistencies, including:
- Unused keymaps.
- Unknown/unused data in the keymap.
- Event arguments that don't make sense.
- Event values that don't match the event type
(tweak direction on keyboard event for example).
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.
Currently (in geometry nodes) you can delete the group input or group
output nodes with no way to get them back without copy and paste. This
adds them to the "Group" submenu of the add menu so at least there is
a way to add them back.
Additionally, these nodes are moved to the "Group" submenu for all node
editors. This makes sense since they are not like the other input or
output nodes, they really just relate to how groups are organized.

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.
There is no reason to hide the 'Scale' and 'Scale Randomness' options
for fluid particles that are rendered as 'Object'.
It is possible that hiding these options was just an oversight and
not intentional.
