The face normal was used in local space whereas it is needed as a global
direction (since other vectors here are in worldspace as well --
knife_input_ray_segment() returns worldspace).
Could go into 3.3 LTS.

e5ec04d73c changed the way crease vakyes are stored in 4.0.
Add versioning for reading the new files that replaces the new generic
attributes with the old non-generic custom data layers. The code is
paranoid with lots fo checks I expect will typically not be necessary.
Similar to f75af7cbf5
Interpolation from edge attributes is unsupported, and the data
of the new point attribute was uninitialized. As a fix, just avoid
interpolating edge attributes in the first place.
PyUnicode_AsUTF8AndSize is used when renaming a custom python property,
this method stores the size of the string without including the null
terminator in the size.
Renaming a custom python property now includes the null terminator when
copying the new string name.

The split edges code had a complex method of merging duplicate edges,
going backwards to avoid shifting elements in a vector. Sometimes it
could result in incorrect corner edge indices though, if it moved an
index that matched one of the local variables (I think! I've bee
trying to understand this all day and still struggling). Instead,
replace it with a `VectorSet` that handles the deduplication by
itself, and avoid creating the new edges until the end.
I think this code could still be simpler if we tried to reduce the
amount of things happening at the same time, making more code
deal with the input or final state rather than an in-between one.
But to avoid making the change too complicated I stopped here.

Before 4369627e71, the Mirror modifier merge did not interpolate
customdata.
Previously, the customdata was simply copied from the original vertex
during the merge, resulting in the retention of flags such as
`MVERT_SKIN_ROOT`.
This fix could just repeat that behavior for mirror. But these flags
can be useful in other cases, so this commit re-adds them to the
resulting merged vertex.
Although this can generate geometries with multiple roots on the same
island, there are different scenarios in which this can happen.
Therefore, multiple roots on the same island is not necessarily
considered a bug.
Socket shapes are used in geometry nodes to indicate field types.
In other tree types (e.g. shaders) the socket shape is not touched at
all. Since nodes can be copied from geometry node trees, we need to
reset the socket shape when copying to a shader, compositor, or texture
tree.

Bug in Metal when gl_FragDepth is used but not written to by a shader

Pinning information was accidentally skipped inside of the
UV packing engine because of their ordering.
This was most noticeable when using the "Bounding Box" shape
method, causing some pinned islands to be moved when they
should have been locked in place.
Fixes#108730
The call to `CustomData_interp` also interpolated the face corner
topology attributes, which broke the mesh completely. To fix this,
avoid relying on the CustomData API and move the attribute
interpolation to use the attribute API instead. This change also
makes it trivial to support all attribute types in the future.
Also, only retrieve the closest vertex once, instead of doing it
again for every attribute. Combined with building the topology
maps in parallel this approximately doubled the performance
of color attribute propagation in a test with 2 million vertices
and 8 color attributes on both domains (63 to 34 ms).

Ensure buffer read operations wait for pending GPU work to
complete. This is only required for unit tests, but required to
ensure correct results in all cases. Also adds support for staging
buffer if GPU memory type is private.
Buffer clearing routine added to support values above 1 byte.
The previous buffer clearing functionality using fillBuffer writes
values to each byte, rather than the full 32 bit uint used by the
GPU API.

The graph editor has the function to hide the display of FCurves and to only draw keyframes on selected curves.
Both options were not respected when executing the frame jump operator,
meaning it would jump to potentially hidden keyframes.
This patch adds a new operator that is specific to the Graph Editor and that respects those features.
The only possible issue that could arise from this is a slight confusion for the user
why they behave differently between editors.
Especially with only the Graph Editor and the 3D view open.
In general I think it's an improvement and follows the "you can only modify what you see" mantra in blender

Issue here was that Quick Favorites use a property's **identifier** when
adding [which is the bare name without brackets etc. from id properties]
but when spawning the actual menu, `RNA_struct_find_property` expects
the identifier to already include the brackets to know these are id
properties (later on in `screen_user_menu_draw`).
So to solve this, now include the needed syntax when storing the
`bUserMenuItem_Prop` identfier.
Seems the quickest way to append the needed characters is using
`RNA_path_property_py` (not sure if there are better ways to do this).
Also note that we (need to) ignore the actual array index constructing
the string [always pass -1 here] since the index is handled separately [I
tested boolean arrays and these work].

During uv unwrapping and uv packing, certain floating point algorithms
have extreme sensitivity to round-off errors. These can produce very
different layouts even when given inputs which are only slightly different.
The root cause is that the two main types of CPUs used to run Blender,
namely x86 and Apple Silicon, produce slightly different results on some
math functions, including `sinf()`, `cosf()` and `atan2f()`.
* sinf(0.8960554599761962890625) = 0.780868828296661376953125 (Intel i7)
* sinf(0.8960554599761962890625) = 0.78086888790130615234375 (Apple M1)
This fix, and others that came before it [0], improve accuracy by using
double-precision to hide the differences between the CPUs.

Occlusion must consider several factors:
- The `Viewport Display` > `Display As` setting of the object.
- The X-Ray mode of the scene.
- Whether only Snap to Face is being used.
- Whether Snap is set to Cage (always transparent) in edit mode.
- Whether the object is hidden.
In the case of Cage, the final geometry should be utilized for occlusion.
However, to prevent excessive and risky modifications, it was followed
the same approach as before and verified the `Display As` setting of
the object.
In particular, the root was not sticking to mesh with hair dynamics.
Reason for this is missing HairKey weight upon conversion (everything
had zero weight). This then can not be corrected (since weight tool does
not allow to paint on roots).
So now, give the hair a default 1.0 to 0.0 weight gradient upon
conversion [which is in line with the default weight distribution for a
hair particle system].

Part of the checks to see if translating a UI string is allowed or not
is that current thread is the main one. This was a requirement years ago
of the Boost backend for translations.
Not sure whether this can be removed or not now, but it needs to be
carefully checked, done it as its own commit, and not in a beta release
branch. ;)
Sorry for the noise, totally missed this during the patch review
yesterday.
Pasting numerical array buttons happens with `Ctrl + Alt + V`.
Holding `Alt` also triggers uiSelectContext, so having other nodes/
objects etc. selected while doing this would try to copy the pasted
values back to other objects (possibly to the ones you pasted from) and
that happens relative to the original value, so the value actually
changes.
NOTE: the `Ctrl + Alt + V` shortcut can also be used on non-array buttons, so was an issue for them as well.
To prevent the "copy-to-selected" behavior, refine the `IS_ALLSELECT_EVENT` macro to be more specific.

References to data-blocks in a material were stored in-memory and could
crash if the data-blocks referenced by the material no longer existed
when pasting.
Resolve by using a blend-file for material copy/paste, matching how the
clipboard works in the 3D view-port.
Currently there is no support for including indirectly linked
data-blocks when pasting the material. Instead, data-blocks are restored
by name, by inspecting the current file.
This also fixes a crash where the `SpaceNode::nodetree` could point to
freed memory when pasting a material.

`hair_out_mesh` and `hair_in_mesh` implicitly share edges.
In `hair_create_input_mesh()`, edge data of `hair_in_mesh` needs to be
updated and therefore are copied to a new location. In the subsequent
frames, `psys->clmd->clothObject->edges` won't be updated and point to
freed memory block. Therefore, Blender crashes.
By freeing `hair_out_mesh` first,
1. in `hair_create_input_mesh(),` at least edge data copying is avoided
2. `psys->clmd->clothObject->edges` always points to correct memory
However, since it's possible that similar situation will happen again
by adding another strong user to the same `CustomData` in the future,
it is safer to update `psys->clmd->clothObject->edges` for every frame.

The "Fill" message can be either a noun or a verb. This commit
disambiguates the verb usages for translation through various
translation contexts.
The more involved change is in the generation of keymaps from paint
modes. By default, the enums defining brush names are in the default
context, but this commit changes the ones including a "Fill" item to
"Brush". In order to get the same contexts in the keymap, we introduce
a specific function in `paint.cc` to return the appropriate context
depending on the tool.

This came up in #108096
Reason this fails is the `ui_but_has_array_value` check [which depends
on a property subtype that supports arrays]. The default `VectorBuilder`
has a `PropertySubType` of `PROP_NONE` though, so one possibility
would be to change this to `PROP_XYZ`.
However, RNA should know much better which RNA property buttons
have arrays than the UI code, so use RNA_property_array_check now
(instead of checking particular UI property subtypes).
