Removed unwanted return statements

Geometry Nodes: fix z-up spline normal calculation

Previously it didn't work when the tangents were collinear to the z axis.

Raycast geometry node.

The *Raycast* node intersects rays from one geometry onto another.
It computes hit points on the target mesh and returns normals, distances
and any surface attribute specified by the user.

A ray starts on each point of the input *Geometry*. Rays continue
in the *Ray Direction* until they either hit the *Target Geometry*
or reach the *Ray Length* limit. If the target is hit, the value of the
*Is Hit* attribute in the output mesh will be true. *Hit Position*,
*Hit Normal*, *Hit Distance* and *Hit Index* are the properties of the
target mesh at the intersection point. In addition, a *Target Attribute*
can be specified that is interpolated at the hit point and the result
stored in *Hit Attribute*.

bli: generational_arena: extra insert() test case with fix

When the capacity of the `Arena` is 0, need to handle it specially.

Make raycast node wider by default.

Non-zero default value for ray length.

Added a mapping mode to enable nearest point.

This would be useful in cases where attributes contain unique per-vertex
values and interpolation over triangles makes no sense. Similar to the
transfer attribute node, but raycast always looks at face corners
rather than arbitrary closes points/edges/faces of the source mesh.

No new features implemented, added comments to overlay/shaders/vector_vert.glsl

bli: generational_arena: remove() with test

bli: generational_arena: get related tests and respective fixes

Alerted ctest with failed or pass

Added a global file count base condition, in case of failure
recursion. Added exit condition for errors.

Merge branch 'master' into cycles_procedural_api

Alembic procedural: support reading per-vertex UV sets

This adds support for importing UV sets which are defined per vertex,
instead of per face corners. Such UV sets can be generated when the
mesh is split according to UV islands, or when there is only one UV
island, in which cases only a single UV value can be stored per
vertex since vertices will never be on a seam.

Fix outdated face tessellation use when editing edit-mesh coodinates

Fix image space missing mask display panel

Remove unused functions.

Fix modifier deform by armature check ignoring virtual modifiers

Regression in f00cb93dbec7bf5dc05302c868f20fcd5aed7db7 (fix for T63125)

Docs: remove deprecated parameter from bmesh docs

The perimeter itself was removed but the documentation wasn't updated.

Resolves T89013

Sketch of better scope handling.

This will require some deeper changes, and keeping track of the scope
infos across time to properly work.

LineArt: Camera marker update fix.

The original fix was probably flushed by some newer
line art commits. Fixed.
