This should not be allowed in general, added some initial call to check
when user is allowed to delete a data to search for mandatory override
usages...
`BKE_object_material_slot_used` would only check obdata usages, but
particle settings can also (weirdly enough) use objects' material slots.
So now, as its name suggests, `BKE_object_material_slot_used` does take
an object as parameter, and also checks for potential slot usage from
psys in the object.
Creating some primitives allows for a scale value (via python) that will
scale the object accordingly. For objects with a radius parameter
(like cylinders, spheres, etc.) passing a scale different to (1,1,1)
would result in unexpected behavior.
For example:
`>>> bpy.ops.mesh.primitive_uv_sphere_add(radius=2, scale=(1,1,2))`
We would expect this to create a sphere with a radius of 2
(dimensions 4,4,4) and then be scaled *2 along the z-axis
(dimensions 4,4,8). But this would previously create a scaled sphere
with dimensions (2,2,4).
The scale was simply divided by two. Maybe because the "radius"
parameter for creating the primitives was confusingly named "diameter"
(but used as the radius).
The fix adds a scale parameter to `ED_object_new_primitive_matrix`
and also renames the wrongly named "diameter" parameters to "radius".

Previously, the Point Instance node in geometry nodes could only instance
existing objects or collections. The reason was that large parts of Blender
worked under the assumption that objects are the main unit of instancing.
Now we also want to instance geometry within an object, so a slightly larger
refactor was necessary.
This should not affect files that do not use the new kind of instances.
The main change is a redefinition of what "instanced data" is. Now, an
instances is a cow-object + object-data (the geometry). This can be nicely
seen in `struct DupliObject`. This allows the same object to generate
multiple geometries of different types which can be instanced individually.
A nice side effect of this refactor is that having multiple geometry components
is not a special case in the depsgraph object iterator anymore, because those
components are integrated with the `DupliObject` system.
Unfortunately, different systems that work with instances in Blender (e.g.
render engines and exporters) often work under the assumption that objects are
the main unit of instancing. So those have to be updated as well to be able to
handle the new instances. This patch updates Cycles, EEVEE and other viewport
engines. Exporters have not been updated yet. Some minimal (not master-ready)
changes to update the obj and alembic exporters can be found in P2336 and P2335.
Different file formats may want to handle these new instances in different ways.
For users, the only thing that changed is that the Point Instance node now
has a geometry mode.
This also fixes T88454.

We need to separate the flag telling duplicate code to not handle
remapping to new IDs etc., from the one telling the code that we are
currently duplicating a 'root' ID (i.e. not a dependency of another
duplicated ID).
This whole duplicate code/logic is still fairly unsatisfying, think it
will need further refactor, or maybe even re-design, at some point...
This patch adds the missing ability to keep the vertex groups when converting to a grease pencil object. This is increadible useful to create rigged grease pencil objects which move together with rigged meshes.

This makes the internal naming consistent with the public API. And also gives
us a visibility_flag rather than restrictflag that can be extended with more
flags.
`BKE_displist_make_curveTypes` had a `for_orco` argument that was
always false in calls to the function. Removing it allows the curve
displist and modifier evaluation code to become simpler. There are
some related cleanups in rBdf4299465279 and rB93aecd2b8107.
The operator run when dropping objects would duplicate the dropped object and
place that in the scene, even though that was just appended. Addressed by
making the duplication optional for the operator. If the duplication is not
requested, the object is just added to the scene (if needed), repositioned
based on the drop location and selected (deselecting other objects).
This makes the operator work as expected when using it to drop assets.

Talked with Bastien and we ended up looking into this. Issue is that the
dupliation through drag & drop should also be considered a
"sub-process", like Shift+D duplicating does. Added a comment explaining
why this is needed.
This patch removes unnecessary calls to `BKE_main_id_tag_all` where the

As the CU_2D flag is set for nurbs, a Curve can have 2D nurbs mixed with 3D.
But the UI does not allow this mixing. It updates all nurbs to 2D or 3D when set.
So remove this specific flag for nurbs.
This may break old files, since 2D curves with mixed 3D are now set as 3D.

We would not add the "object line art" enum to the operator enum list,
if there were no active object in the scene.
This would make it impossible to call this operator from python code as
the enum would we hidden when we were not in a viewport context.
Always make the operator available, having no active object is not a
strict requirement for the operator to work, so expose it always.
This adds the LineArt grease pencil modifier.
It takes objects or collections as input and generates various grease
pencil lines from these objects with the help of the active scene
camera. For example it can generate contour lines, intersection lines
and crease lines to name a few.
This is really useful as artists can then use 3D meshes to automatically
generate grease pencil lines for characters, enviroments or other
visualization purposes.
These lines can then be baked and edited as regular grease pencil lines.
