`remember_deformed_curve_positions_if_necessary` has to be called before
topology changing operations on curves. Otherwise the crazy-space data
is invalid.
The help circles to fill areas were rotated with the object rotation,
but as the stroke is part of the object, apply the rot matrix again
produced a double rotation, so it can be removed.
Two properties are now exposed in python API :
time of each point, and inittime of each stroke.

Only one point should be used to create a reference rotation for other
points to follow. Using two caused the resulting twist to be
asymmetric, especially noticeable on symmetrical, cyclic curves.
Alternate fix to D11886 which caused T101843.
After object-mode undo (memfile undo), the value wan't lost, but the
property would be temporarily converted back to integer type in order
to be forward compatible. Now only use the forward compatible
writing when writing undo steps. Auto-saves and similar files are
currently not forward compatible anyway.
Make the functions more flexible and more generic by changing the curves
arguments to the curve offsets. This way, theoretically they could become
normal utility functions in the future. Also do a consistency pass over
the algorithms that generate new curves geometry for naming and
code ordering, and use of utility functions. The functions are really
quite similar, and it's much easier to tell this way.
The most time-consuming operation in merge by distance is to find
duplicate faces (faces that are different but have the same vertices).
Therefore, some strategies were planned to optimize this algorithm:
- Store the corner indices in an array thus avoiding multiple calls of `weld_iter_loop_of_poly_next`;
- Create a map of polygons linked to edges instead of linked to vertices - this decreases the number of connections and reduces the calculation of the intersection of polygon indices.
There are other fields to optimize, like reusing the `wpolys` array
instead of creating a new array of corner offsets. And join some arrays
as members of the same struct to be used in the same buffer.
But for now, it is already a nice optimization. And the new
`poly_find_doubles` function can be reused in the future to create a
generic utility.
The result of the optimization varies greatly depending on the number
of polygons, the size of each polygon and the number of duplicates.
On average it was something around 2 times faster.
Worst case tested (old vs new): 0.1ms vs 0.3ms

`PBVH_Leaf` nodes are now split into a new `PBVH_TexLeaf`

Rewrite of the Workbench engine using C++ and the new Draw Manager API.
The new engine can be enabled in Blender `Preferences > Experimental > Workbench Next`.
After that, the engine can be selected in `Properties > Scene > Render Engine`.
When `Workbench Next` is the active engine, it also handles the `Solid` viewport mode rendering.
The rewrite aims to be functionally equivalent to the current Workbench engine, but it also includes some small fixes/tweaks:
- `In Front` rendered objects now work correctly with DoF and Shadows.
- The `Sampling > Viewport` setting is actually used when the viewport is in `Render Mode`.
- In `Texture` mode, textured materials also use the material properties. (Previously, only non textured materials would)
To do:
- Sculpt PBVH.
- Volume rendering.
- Hair rendering.
- Use the "no_geom" shader versions for shadow rendering.
- Decide the final API for custom visibility culling (Needed for shadows).
- Profile/optimize.
Known Issues:
- Matcaps are not loaded until they’re shown elsewhere. (e.g. when opening the `Viewort Shading` UI)
- Outlines are drawn between different materials of the same object. (Each material submesh has its own object handle)

Improve handling for cases where maximum in-flight command buffer count is exceeded. This can occur during light-baking operations. Ensures the application handles this gracefully and also improves workload pipelining by situationally stalling until GPU work has completed, if too much work is queued up.
This may have a tangible benefit for T103742 by ensuring Blender does not queue up too much GPU work.

This patch fixes an issue where Blender 3.5 alpha with the Metal GPU backend enabled on Japanese macOS fails to compile shaders and crashes on startup.
In a Japanese environment, `defaultCStringEncoding` is the legacy MacJapanese encoding, and it erroneously converts backslashes (0x5c) to Yen symbols (¥).
Therefore, Metal shader compile fails with the following log and Blender crashes.

The code in questions comes from Shewchuk's triangle code, which
hasn't been updated to fix the out-of-buffer access problem
that ASAN finds in the delaunay unit test. The problem is benign:
the code would exit the loop before using the value fetched from
beyond the end of the buffer, but to make ASAN happy, I put in
a couple extra tests to not fetch values that aren't going to be used.
There's a compromise of a code parameter called BEVEL_GOOD_ANGLE,
and bugs T44961, T86768, T95335, and this one, are all about problems
with various values of that parameter. If an angle of an adjacent
non-beveled edge is too close to that of the beveled edge, then you
get spikes. The BEVEL_GOOD_ANGLE says that if you are within that
angle difference, then no bevel happens. If the value is too small
then one gets spikes for certain models people build; if the value
is too large, then other people are annoyed that no bevel happens.
Hopefully this compromise in this commit is the final one I will do
before switching to Bevel v2, where none of this should be an issue.

This can improve performance in some circumstances when there are
vectorized and/or unrolled loops. I especially noticed that this helps
a lot while working on D16970 (got a 10-20% speedup there by avoiding
running into the non-vectorized fallback loop too often).
Caused by {rB841df831e89d} and {rB3558bb8eae75}.
These commits moved flags from `eLineArtGPencilModifierFlags` to
`eLineartMainFlags`, but later on in code, these were still evaluated
from the modifiers `flags` (instead of `calculation_flags`).
This resulted in a false condition (`match_output` was assumed true but
it wasnt), leading to a wrong codepath taken.
This is now corrected (`calculation_flags` need to be passed around for
this as well).
