LineArt: Cache related wording changes.

Cleanup: Refactoring

LineArt: Working BVH intersection.

bli: generational_arena: test for ensuring next_free list is correct

Cleanup: Moved knife data init code into correct function

Knife: Updated header/footer for constrained axis

Now the header/footer shows X,Y,Z when constrained globally in the respective axis and x,y,z when constrained locally.

Fix T86956: VSE shading mode ignores Grease Pencil Vertex colors.

Issue is that due to the strange definition of render in grease pencil
(meaning should be rendered similar to rendering). This included normal
viewport rendering in OB_RENDER and OpenGL render in OB_RENDER.

For other rendering modes the overlay vertex opacity would be used. This
patch sets this value to 1 when rendering via a scene strip override.

NOTE: that this isn't a good solution as I expect that users want to use
the opacity of the Grease pencil object. Perhaps the GPencil team has a
better solution for it.

Versionbump: Blender 2.83.17-rc

Removed unwanted return statements

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.
