In case of line art "occlusion only" or contour not enabled, it's possible for an object
to not produce any feature lines.
This patch checks that to prevent freeing a NULL pointer.

This reverts commit 14a5a91e0e033d712134c112a4778b495bd73ba1.
This caused build errors on x64+arm mac builds and some versions
of MSVC, reverting for now till a better solution is found.

Using the atomic "compare and swap" method in add_triangles stage
dramatically speeds up the add_triangles call and significantly reduced
the overall calculation time. This is currently the fastest method we
have experimented with so far.

This patch adds 4th option to Time offset modifier Modes.
It loops from start frame to end frame and then back to start in reverse direction.
In other words it is a combination of Normal and Reverse mode.
Especially with offset control it adds the ability to create easy looping animations such as cheering crowds, flowers opening and closing at different offsets.

It turns out there's no practical use for separating different edge types
before final occlusion stage, also using an array should be faster overall.
So changed those lists into one pending array, it also made the
iteration and occlusion task scheduling simpler.

This change allows the chaining function to select edges
from the same contour loop first, thus reduced rouge chain
connections (connected different objects instead of chaining
inside the same object first) and improved chaining quality.
This patch also included the default value change for chain
split threshold (Now don't split by default to make initial
result as smooth as possible)

This is for some animation styles that usually copy and paste keyframes and they want avoid that both frames look equal, but they don't want noise randomness changes in the inbetween frames.

When using an offset modifier on a grease pencil object, the performance
could be impacted due to the randomize option introduced by rB6a2bc40e0131.
Even if the option was not used (offset, rotation, scale set to zero), the modifier
would still compute the random transformation matrix.
The patch checks if the randomization is used and only then caluclates the matrix.

The new created strokes were not setting the right `orig` pointers, so the select operator could not select the strokes and points.
Now, the original pointers are set in the new strokes. To set the values is necessary assign the original pointer from the reference stroke because in modifiers the stroke is evaluated, so we need back two levels: Eval->Eval->Orig

- Missing star prefix.
- Unnecessary indentation.
- Blank line after dot-points

This has been broken for two years, since rB29f3af952725,
which retrieved the bounding box from an object and immediately
overwrote it with -1, 1. That commit had another problem though--
the modifier stack shouldn't use object level data, it should use
data from the previous modifier.

Also solves two warnings from the previous similar commit,

This patch makes the grease pencil smooth operation symmetric.
It also increases the performance a lot if strong smoothing is
required. Additionally there is an option for the position smooth
operation to keep the shape closer to the original for more iterations.
Since the result differs from the previous algorithm, versioning is used
to change the iterations and factor to match the old result.

This new modifier creates a shape known as envelope. It connects all
points that are n points apart. There is also a mode which fits a
single stroke to the envelope shape that is determined by that rule.

Currently there is a "calc_face_normal" argument to mesh to bmesh
conversion, but vertex normals had always implicitly inherited whatever
dirty state the mesh input's vertex normals were in. Probably they were
most often assumed to not be dirty, but this was never really correct in
the general case.
Ever since the refactor to move vertex normals out of mesh vertices,
cfa53e0fbeed7178c7, the copying logic has been explicit: copy the
normals when they are not dirty. But it turns out that more control is
needed, and sometimes normals should be calculated for the resulting
BMesh.
This commit adds an option to the conversion to calculate vertex
normals, true by default. In almost all places except the decimate
and edge split modifiers, I just copied the value of the
"calc_face_normals" argument.
