There were multiple reports with objects having many empty material
slots.
The underlying reason for this is the behavior of adding/assigning
materials [which makes room in the form of empty material slots based on
the current `active_material_index` -- which atm. can be set to
arbitrary values]. So just e.g. setting this to 100 in a fresh file and
assigning a material would create 99 empty slots.
To resolve, now clamp to the existing number of material slots.
NOTE: there is already a range function defined, but this actually only
kicks in from the animation system (so clamping would take place there),
so clamping is expected to happen in the set functions (there is also a
related comment in `RNA_property_int_set`)

The problem happens because, on some OSs, `wm->winactive` is `nullptr`.
Another problem is that `wm->winactive->eventstate` sometimes does not
update when the mouse moves. This happens in some OSs when the cursor
is not over the active window. So the snap cursor state doesn't update.
The solution is to use the `eventstate` of the window in the context
(`CTX_wm_window(C)->eventstate`).
This matches other parts where `eventstate` is used.

This PR adds an option to specify custom colors for a
motion path. One for frames before the current frame
and one frame for after. With this it is easier to see
the relation of the motion path to the current frame.
That was already the case with the default colors, but
not with custom colors.
On a technical side note, the colors pre and post the current
frame were already different.
The shader multiplied the custom color by 0.25
for anything pre current frame.

In the case that "Custom Properties" was enabled in the user preferences,
the keyframing code would key all custom properties, regardless of that
property's type.
This can cause issues since it is keying e.g. the custom property that
cycles adds.
With this PR this is now limited to only Boolean, Int, Float, Double and Array.
Custom properties that have been defined via an addon are also not keyed.

In GPv2 there was an option to disable masks during rendering
of a viewlayer. This wasn't implemented for GPv3 yet.
This needs to change the way the draw calls are created,
because we need to skip over drawings at render time.
So to do this, we precompute the drawing offsets,
then check if we need to skip over it and otherwise
create the draw calls.

Caused by ca0b02aa96.
The `points.size() > 1` was added because we can't access
`lengths[points.size() - 1]` if the curve has a single point.
The fix just makes sure we default to a `u` value of `0.0f`
for single point cyclic curves.

While the drawing code already skipped drawing any key points that are not in view,
it did that with an `if` check within the `for` loop. This can be speed up quite a bit
by calculating the bounding indices beforehand and only iterating that range.

On heavy scenes, the function `get_graph_keyframe_extents`
takes up a considerable amount of the time (~50%) it takes to draw the Graph Editor.
This function is called to set the `View2D` extents which makes the scrollbars work properly.
I'd argue that level of precision isn't needed just to display scrollbars.
Passing the flag as `false` speeds up the drawing code by 22%.

Inherited from previous versions of this feature, by default the Purge
operation from the Outliner would remove all unused IDs, recursively.
The same operation invoked from the File -> Clean Up main menu would by
default only delete directly unused IDs.
Now both will by default remove all (directly or indirectly) unused data.
Object names can contain "/" & "\" and aren't safe to use in paths,
use BLI_path_make_safe_filename to ensure the name can be used in a
path.

Regression caused by [0], also correct memcpy calls that overwrite

This is needed so we can reliably know which extension is associated
with a theme, so a theme can be refreshed on update and cleared when
uninstalled, needed to resolve!120289.
Currently the node tools asset tree for extending 3D view headers is
rebuilt whenever it's cleared, which is done by clearing the tree's storage.
That means the data is rebuilt on every redraw if there are no node tools
and the tree storage is empty. With larger asset libraries that can be
quite expensive.
Now, instead of clearing the map, use a new dirty tag to store whether
the asset tree is out of date compared to the assets.
This should resolve#120494
This PR moves the three sculpt trim gesture variables from
`SculptSession` into the `TrimOperation` `struct` to reduce
the size of the former and make it less likely that the data
is depended on in other operators.

This cleans up our `TEST_SSE_SUPPORT` macro to only test
for SSE42 and passes the flags to the CMAKE_C/CXX_FLAGS
the cpu check module needed to move to its own folder since
the flags at the end of a CMakeLists.txt appear to be used
for all targets inside a CMakeLists file and cpu_check cannot
be build with sse42 flags.
This only affects Mac/Linux since MSVC has no buildflags
to target SSE42

In GPv2 strokes could technically have zero points.
`CurvesGeometry` doesn't allow this, so we need to make
sure to explicitly skip over strokes with no points.

Not all matrices are invertable (e.g. when a transformation matrix is has
a scale of zero), and it's sometimes important when a matrix is.
This also better specifies the behavior when the matrix is not invertable:
the identity matrix is returned.

A small logic issue caused all write-only image resources
to be tagged as read-write in all cases. This caused
correctness issues on Intel and AMD GPUs which
are resolved through this change.
Change also yields a small performance uplift
due to enabling improved non-dependent workload
scheduling.

This PR performs the following refactors in sculpt_trim.cc:
* Remove `depth_front` and `depth_back` as `struct` properties, as they
are only used for generating the Mesh
* Moves the `calculate_depth` call into the `generate_geometry` step as
the latter is dependent on data from the former already
* Reorganize the methods so the overall file reads better.
* Minor comment nits and additions

The reverse uv sampling operation generally fails when there the sample position
is within more than one uv triangle. Unfortunately, the combination of limited
floating point accuracy and very small triangle areas caused this case
sometimes, even if the triangles don't actually overlap. This happens relatively
rarely, but if it does, it causes annoying artifacts. The solution is to only
detect these kinds of overlapping triangles if they have a certain minimum size
and to be more relaxed otherwise.

Make it match behavior of the previous Python importer: it was
accepting such faces, and then always calling mesh validation function
that got rid of them. Instead of doing the whole validation cost,
just do not add such faces in the first place.
Historically makesdna/rna did not link bf_guardedalloc for
some reason, but during one of my cmake cleanups have picked up
this dependency anyhow. To prevent duplicate symbols, remove the
now duplicated translation units as linking bf_guardedalloc has
seemingly not caused any issues.

Bone collections are drawn in the new tree view by accessing properties
from `armature.collections_all[...]`, which means that drivers and
fcurves also target those. This is now taken into account when updating
the bone collection name.
For context: in Blender 4.0 the UIList used `.collections[...]` instead,
for which renaming was already handled properly.
Pull Request: https://projects.blender.org/blender/blender/pulls/120517
Use versioning code to change Drivers & F-Curves targeting
`armature.collections[...` to target `armature.collections_all[...`
instead. The former contains the root collections only, whereas the
latter contains all of them in a flat list. Not only does this fix the
tree view (it binds to properties via the `.collections_all` RNA path),
but also this makes the drivers & animation of the properties work even
when the hierarchy changes.
Note that both `.collections` and `.collections_all` give access to all
bone collections. The former just requires iterating hierarchically,
that is, via `some_collection.children`.

Adds support for subpass transition for AMD/Intel IMR
GPUs. This enables correct functioning of EEVEE Next
deferred lighting pass on AMD platforms.
The emulation is consistent with the OpenGL approach
of generating additional texture bindings in the shader
for subpass inputs, and splitting render passes across
sub-pass boundaries.
