Use active object accessor, and then access data from the
object. There is no need to have an API call for shortcut
of all object fields.
Should be no functional change.
Instead of generating a dependency sorted node list whenever evaluating
texture or EEVEE/viewport shader nodes, use the existing sorted array
from the topology cache. This may be more efficient because the
algorithm isn't quadratic. It's also the second-to-last place to
use `node.runtime->level`, which can be removed soon.

Rewrite the edge split code to operate directly on Mesh instead
of BMesh. This allows for the use of multi-threading and makes
the node around 2 times faster. Around 15% of the time is spent
just on the creation of the topology maps, so these being cached
on the mesh could cause an even greater speedup. The new node
gave identical results compared to the BMesh version on all the
meshes I tested it on (up to permutation of the indices).
Here are some of the results on a few simple test cases:
(Intel i7-7700HQ (8 cores) @ 2.800GHz , with 50% of edges selected)
| | 370x370 UV Sphere | 400x400 Grid | Suzanne 4 subdiv levels |
| ----- | ----------------- | -------------- | --------------------- |
| Mesh | 89ms | 111ms | 76ms |
| BMesh | 200ms | 276ms | 208ms |

As part of T95966, this patch moves loose edge information out of the
flag on each edge and into a new lazily calculated cache in mesh
runtime data. The number of loose edges is also cached, so further
processing can be skipped completely when there are no loose edges.
Previously the `ME_LOOSEEDGE` flag was updated on a "best effort"
basis. In order to be sure that it was correct, you had to be sure
to call `BKE_mesh_calc_edges_loose` first. Now the loose edge tag
is always correct. It also doesn't have to be calculated eagerly
in various places like the screw modifier where the complexity
wasn't worth the theoretical performance benefit.
The patch also adds a function to eagerly set the number of loose
edges to zero to avoid building the cache. This is used by various
primitive nodes, with the goal of improving drawing performance.
This results in a few ms shaved off extracting draw data for some
large meshes in my tests.
In the Python API, `MeshEdge.is_loose` is no longer editable.
No built-in addons set the value anyway. The upside is that
addons can be sure the data is correct based on the mesh.
**Tests**
There is one test failure in the Python OBJ exporter: `export_obj_cube`
that happens because of existing incorrect versioning. Opening the
file in master, all the edges were set to "loose", which is fixed
by this patch.

This separates the UV reverse sampling and the barycentric mixing of
the mesh attribute into separate multi-functions. This separates
concerns and allows for future de-duplication of the UV sampling
function if that is implemented as an optimization pass. That would
be helpful since it's the much more expensive operation.
This was simplified by returning the triangle index in the reverse
UV sampler rather than a pointer to the triangle, which required
passing a span of triangles separately in a few places.
* This patch just moves runtime data to the runtime struct to cleanup
the dna struct. Arguably, some of this data should not even be there
because it's very use case specific. This can be cleaned up separately.
* `miniwidth` was removed completely, because it was not used anywhere.
The corresponding rna property `width_hidden` is kept to avoid
script breakage, but does not do anything (e.g. node wrangler sets it).
* Since rna is in C, some helper functions where added to access the
C++ runtime data from rna.
* This size of `bNode` decreases from 432 to 368 bytes.
As described in T100004, add an output socket that returns true if the
attribute accessed by the node was already present in that context.

I18n: make a few messages translatable
* Missing Paths * in the Presets menu when no preset exists yet.
The White Noise entry in the Add Node menu is the only one lacking a "Texture" suffix, which doesn't seem justified since the node itself is already called "White Noise Texture". Rename the entry its name can be extracted and used for the node--and for consistency.
New object material node names (Principled BSDF, Material Output) come from a preset node tree. The nodes' names need to be translated after creation.
Extract the "Fallback Tool" pie menu title.
Translate grease pencil options in the viewport overlay menu.

When dragging out a boolean noodle, releasing and choosing
'switch > Switch' from the search popup, the code would mistakenly
search for 'Start' instead of 'Switch'.
Also the function called was not exactly the right one, leading to the

* Support bidirectional type lookups. E.g. finding the base type of a
field was supported, but not the other way around. This also removes
the todo in `get_vector_type`. To achieve this, types have to be
registered up-front.
* Separate `CPPType` from other "type traits". For example, previously
`ValueOrFieldCPPType` adds additional behavior on top of `CPPType`.
Previously, it was a subclass, now it just contains a reference to the
`CPPType` it corresponds to. This follows the composition-over-inheritance
idea. This makes it easier to have self-contained "type traits" without
having to put everything into `CPPType`.

Correct trim for cyclical curves mentioned in T101379, splitting the
curves if the start/endpoint is at the 'loop point'.
Correct implementation based on comments in D14481, request was made to
use 'foreach_curve_by_type' to computing the point lookups.
Included corrections from D16066 as it may not be a adopted solution.
Exposed selection input by adding it as input to the node.

The preferred domain is used to decide which domain the viewer node
should use when set to "Auto" domain. This commit adds it to some curve
input nodes and the curve and mesh topology nodes. This makes debugging
node setups with these nodes a bit faster and less frustrating.
The "all curve" sampling is implemented as two functions internally.
The first finds which curve each "global" sample should be on. Then
the second is the regular evaluation and sampling in that curve.
The first operations creates lengths, but they were processed as
factors when passed to the second function.
The node has always be a bit confusing for the NURBS case, since it
uses the distance between control points since the evaluated/control
point mapping isn't obvious, but it also went above 1, which wasn't
correct.
Instead, retrieve the total length from the point lengths calculated
in the previous step. The results should be the same for other curve
types.
The new Xcode 14.1 brings the new Apple Clang compiler which
considers sprintf unsafe and geenrates deprecation warnings
suggesting to sue snprintf instead. This only happens for C++
code by default, and C code can still use sprintf without any
warning.
This changes does the following:
- Whenever is trivial replace sprintf() with BLI_snprintf.
- For all other cases use the newly introduced BLI_sprintf
which is a wrapper around sprintf() but without warning.
There is a discouragement note in the BLI_sprintf comment to
suggest use of BLI_snprintf when the size is known.

Use the node topology cache and avoid modifying the node tree

the helper function. Replaces the implementation from
e0d4047136.
Currently there are both "EDGERENDER" and "EDGEDRAW" flags, which are
almost always used together. Both are runtime data and not exposed to
RNA, used to skip drawing some edges after the subdivision surface
modifier. The render flag is a relic of the Blender internal renderer.
This commit removes the render flag and replaces its uses with the
draw flag.
