Update the RNA and DNA documentation for two bone matrices:
- `PoseBone.matrix_channel` (`bPoseChannel::chan_mat` in DNA) contains
the evaluated loc/rot/scale channels, including constraints and drivers.
- `PoseBone.matrix` (`bPoseChannel::pose_mat` in DNA) contains the same
transform, but then expressed in the armature object space.
No functional changes, just clarifications in comments / tooltips.
While embedded IDs are usually considered as private local data of their
owner ID, some areas of code, like the depsgraph, can consider them as
regular IDs in some aspects.
So when swapping IDs, also properly 'counter-swap' their potential
embedded IDs, such that the pointers to the embedded IDs remain as before
swapping, even though the data of the embedded IDs is swapped.
The main target of this change is memfile undo code. There, newly read
IDs are swapped with their oldder version, so that the old address
contains the new data. This allows to avoid rebuilding some of the
depsgraph. Doing the same thing for embedded IDs should reduce even
further the needs for depsgrah rebuilds on undo steps.
This commit also gives more control over the remapping of 'self' ID
pointers inside themselves.

- Split out WM_init_splash_on_startup(..) which performs startup checks.
- WM_init_splash(..) now shows the splash (ignoring preferences).
- Avoid calling BLI_exists on an empty string (in some cases).
Recent failures requiring investigation have exposed some shortcomings
that this addresses:
- When creating the diff image for offline comparison, use a higher
threshold to prevent idiff from printing more output which will often
contradict the primary failure output just above it (very confusing)
- For metadata failures, make sure these get printed so it's obvious
what kind of failure we're dealing with

Due to floating point differences between importance sampling and
texture evaluation, disagreeing on whether or not a ray lies within
the sun disc.
* Use the same input values for geographical_to_direction() in
sky_radiance_nishita() and kernel_data.background.sun.
* The mathematical operations in pdf_uniform_cone() were adjusted to
match sky_radiance_nishita().

This is the first step for refactoring the lightcache system.
Each probe instance (as in `Object`) will now store its own baked data.
The data is currently stored in uncompressed readable format.
This introduces two new operators for baking to avoid confusion with
the previous light baking pipeline. These do nothing other than
creating empty caches that will be populated by EEVEE later on.
The DNA storage is made to be able to include multiple caches
in case of baked simulation over time but it isn't yet supported.
I prefer to keep the implementation simple for now as the long term
goals for this feature are uncertain.
There is still a type flag (`LightProbeObjectCache.cache_type`) that
will be used for versioning.
The naming convention of structs is a bit weird but that's all I
found in order to avoid interfering with the old scene light cache
that is still used by (old) EEVEE.

For non-object parents (so bones & vertices), the parent is now also
explicitly checked for animation. In other words: having an animated
parent will cause the transform of the child to be written to Alembic/USD
on every frame (as if it is animated itself).
Do not read IDs from types flagged as 'no undo', whether they are local
or linked.
This should have no effect currently, since all 'no undo' ID types
currently are supposedly only local data anyways (Screen, WindowManager
and WorkSpace).
These IDs kept their address, but their content has been replaced
(re-read from the memfile undo step). Add an ID tag to identify them.
As a further cleanup, systematically tag these IDs for despgraph COW,
since their data is effectively modified (though in practice all of
these IDs are expected to already have other update tags anyway).
No change in behavior is expected from this commit.
This should not have much effective consequences with current code, but
fixes potential missed remappings for e.g. some nodetree pointers in the
node editor, or the `parent` pointer of collections to a scene's master
collection.
Implements #95966, as the final step of #95965.
This commit changes the storage of mesh edge vertex indices from the
`MEdge` type to the generic `int2` attribute type. This follows the
general design for geometry and the attribute system, where the data
storage type and the usage semantics are separated.
The main benefit of the change is reduced memory usage-- the
requirements of storing mesh edges is reduced by 1/3. For example,
this saves 8MB on a 1 million vertex grid. This also gives performance
benefits to any memory-bound mesh processing algorithm that uses edges.
Another benefit is that all of the edge's vertex indices are
contiguous. In a few cases, it's helpful to process all of them as
`Span<int>` rather than `Span<int2>`. Similarly, the type is more
likely to match a generic format used by a library, or code that
shouldn't know about specific Blender `Mesh` types.
Various Notes:
- The `.edge_verts` name is used to reflect a mapping between domains,
similar to `.corner_verts`, etc. The period means that it the data
shouldn't change arbitrarily by the user or procedural operations.
- `edge[0]` is now used instead of `edge.v1`
- Signed integers are used instead of unsigned to reduce the mixing
of signed-ness, which can be error prone.
- All of the previously used core mesh data types (`MVert`, `MEdge`,
`MLoop`, `MPoly` are now deprecated. Only generic types are used).
- The `vec2i` DNA type is used in the few C files where necessary.

Animation data (including drivers) on inactive view layers now work. The
removal of such view layers was too optimistic; they are now kept
around. The bases are still removed, mostly for safety sake and to keep
the changes to a minimum.
`scene_remove_unused_view_layers()` has been renamed to
`scene_minimize_unused_view_layers()` to reflect its new functionality.
For compatibility with assumptions in other areas of the code, the
function still ensures the input view layer is at index 0.
This also introduces a new function
`BKE_view_layer_free_object_content(view_layer)`, which is a subset of
the functionality of `BKE_view_layer_free()`.
Having a type defined allows the compiler to help with type safety. For
example we can use it in switches to trigger a warning when a new object
type is added but not covered by the switch yet (but probably should).
Currently, when using the python api for offscreen drawing, the
default background will always be rendered into the GPUOffScreen's
framebuffer, rendering the alpha channel essentially useless and
making it difficult to separate objects from the background.
This patch allows offscreen drawing of a 3d view with transparent
background by exposing an optional parameter to the python api,
enabling, for example, compositing the result over another image.
The new parameter to draw_view3d() is optional, with the default
value matching the previous behavior, so this change is fully

Previously, there was a "main" and "tmp" buffer and the final
result was expected to be in the "main" buffer. Now the two buffers
are called a and b and the final result can be in either of those.
This can improve performance especially if the number of iterations is low.

`PyObject_GetBuffer` was used without checking that it was successful.
This could cause the code to access an incompatible or uninitialized
`Py_buffer`.
Add the missing checks, and clears the raised `PyExc_BufferError`
to silently fall back to accessing the PyObject as a sequence.
Using a "//" prefix resolves to the root directory which isn't a good
default as it typically doesn't have write permissions.
Only set the name and let the file selector pick a directory to use
(matches how saving from the text editor works).
Add WM_window_pixels_read & WM_window_pixels_read_sample that
use front-buffer pixel reading when supported.
Note that direct access to reading from the front-buffer is still needed
for writing thumbnails - where redrawing can cause problems
(see code-comments).
