Flickering observed when snapping to edge or face with axis constraint.
It was probably introduced in 4eda60c2d8
The snapping code has a timer, so `t->tsnap.snapElem` isn't always set.
So avoid changing the value of `t->tsnap.snapElem`.
Rather than forcing the user to initiate a transform operation to edit the `Proportional Size`, allow editing of the `Proportional Size` through the UI.

For derived mesh triangulation information, currently the three face
corner indices are stored in the same struct as index of the mesh
polygon the triangle is part of. While those pieces of information are
often used together, they often aren't, and combining them prevents
the indices from being used with generic utilities. It also means that
1/3 more memory has to be written when recalculating the triangulation
after deforming the mesh, and that the entire triangle data has to be
read when only the polygon indices are needed.
This commit splits the polygon index into a separate cache on `Mesh`.
The triangulation data isn't saved to files, so this doesn't affect
.blend files at all.
In a simple test deforming a mesh with geometry nodes, the time used
to recalculate the triangulation reduced from 2.0 ms to 1.6 ms,
increasing overall FPS from 14.6 to 15.

Conditional blocks introduce scopes that need to be kept track of,
linear code is easier to follow. So use early exiting to reduce
cognitive load, a number of devs (including myself) consider this good
practice.
Apple Silicon uses tile rendering and can discard tiles if it
is covered. The retopology overlay made some changes to the
shader that introduced some blocking and striping artifacts when
the overlay was disabled.
This PR changes the minimum used offset to reduce the drawing
artifacts. Tweaking the GLSL shader itself didn't work.
Fix#105830

The simulation cache is allocated lazily during evaluation when the
depsgraph is active. However, during rendering, the depsgraph is not
active, so it's not created.
This is a really rough implementation. Since the MSL sources
do not correspond 1:1 to the GLSL sources, some mapping is
needed to retreive the GLSL source file for a given generated
line. This will be implemented in a later commit.
This addresses #95855 by prioritizing the selection of keys in the following order:
1. Keys on the active curve.
2. Keys on any selected curve.
3. Other keys.
Additionally, this fixes an as-yet unreported issue where you couldn't select the main vertex of a key if it was overlapping with another one and one or more of its handle vertices were already selected. This was due to the selection status of a key and its handles not being properly considered separately.

Previous GHOST_ContextVK would create a logical device for each
context. Blender uses multiple contexts at the same time and wasn't able
to share resources between them as the logical device where different.
This patch will create a single logical device and share them between
multiple contexts. This allows sharing memory/shaders between contexts
and make sure that all memory allocations are freed from the device it
was allocated from.
Some allocations in Blender are freed when there isn't a context, this
was failing in the previous implementation. We didn't noticed it before
as we didn't test multiple contexts.
This patch also moves device specific data structures from VKContext to
VKDevice like the descriptor pools, debug layers etc.

- Names ending with len sometimes referred to the buffer size.
The same names were used for both buffer size and string length
depending on the function in some cases.
- Rename str/string to path for generic path functions.
- Rename BLI_path_rel arguments (file, relfile) to (path, basename)
as it wasn't so clear which is being made relative, `file` can be a
directory so rename to `path` (matches naming for BLI_path_abs).
The size limit used in RNA string access wasn't meaningful as the size
of buffers passed into these functions is defined by the length+1 which
uses strlen, unterminated strings would already cause a buffer overflow.
Note that strcpy for accessing RNA is already widely used,
there were just some cases that used BLI_strncpy too.
This also removes use of BLI_strncpy_utf8 in texture slot access as
names are expected to be utf8, sanitizing when copying in this
particular case doesn't make sense and isn't done elsewhere.
- Avoid inline ifdef checks for DEBUG_STRSIZE
- Add BLI_string_debug_size_after_nil to ensure strings to manipulate
have the expected buffer size after the nil terminator.
- Add checks to more string manipulation functions.
Further changes are required for this to be enabled during regular
development as the RNA currently allocates the strings length but
passes in the buffer size as a limit which conflicts with DEBUG_STRSIZE.
The grab tool in Grease Pencil sculpt mode doesn't work correctly on strokes affected by modifiers.
You had to grab over the original vertex positions to see any effect.

The fact that blenlib doesn't know about the set of attribute types is
actually an important detail right now that can influence how things
are designed. Longer term it would be good to consolidate many of
these attribute propagation algorithms anyway.
The "Evaluate at Index" and "Sample Index" nodes are exactly the same
once they retrieve the values to copy and the indices (apart from the
clamping option anyway). This also allows devirtualizing the index input
in the evaluate at index node like the sample index node.
The logic in the initial commit (97dd107070) was broken in some cases,
and would end up tagging as unused IDs that had valid usages. It is
reverted by this commit..
For this new solution to #98029 (deleting unused archipelagos of data),
the logic handling dependency loops detection is reworked to rely on a
new tag in the relations entry of the relevant IDs, instead of
pre-tagging as unused the ID itself.
Further more, when a dependency loop is detected, the IDs in it cannot
be immediately tagged as unused, since it may be that the entry point
of that loop is later detected as actually used. So their relations
entries are not tagged as processed, and only the entry point of the
potential archipelago can be checked in that case, outside of the
recursive processing of dependencies.
The other IDs of the archipelago will then be processed again later, in
a state where at least one ID in the archipelago has a known state for
sure, which then allows for a safe evaluation of the other related data.
This commit should be backported to 3.3LTS.
Fixed bug where texture alpha was incorrectly remapped to red when exporting material shaders.
Now connecting the UsdPreviewSurface 'opacity' input to the UsdUVTexture 'a' output if the Blender texture image node source socket identifier is 'Alpha'.
Changes include the following:
The InputSpec::source_name struct member was removed, as the connection source name is now determined at runtime based on the Blender node input socket identifier.
The traverse_channel() utility function now returns a bNodeLink*, so that the source socket identifier can be queried from the link.
In create_usd_preview_surface_materia(), the code for creating and connecting a UsdUVTexture shader was reorganized to group it within one conditional block, to make it easier to follow. Also replaced a call to a deprecated version of UsdShadeInput::ConnectToSource().

Change the implementation of the raycast and sample nearest surface
node to split separate loops into separate multi-functions. This
clarifies the task of each function, gives more information to the
field evaluator, and gives more opportunity for memory reuse.
Sampling mesh attributes with triangle barycentric weights is now
implemented in a single place. Two other new multi-functions
handle conversion of sampled positions into barycentric weights.
Normalizing the ray directions for the raycast node is split out
too, so it can be skipped in some cases in the future.
The mesh attribute interpolator helper class is also removed,
since it didn't give much benefit over a more functional approach.
I didn't notice a performance improvement from this change.
