The `BM_mesh_bm_to_me()` function copies shape keys from the BMesh to
the Mesh. However, it tries to copy the same number of shape keys as are
defined on the target mesh. Since the target mesh does not necessarily
have the same number of shape keys as the BMesh, this would crash if the
target Mesh has more.
Found while performing some tests for {D7785}.

Don't use the cube corner special case when the offsets are different
for the three edges involved. The generic VMesh for this situation isn't
perfect, but it's much better than a failed cube corner VMesh.
Tests pass.
Was flipping around the 0-1 range, now (optionally) flip around each tile.
Also added this option for BMesh bmo_mirror.

Starting select linked failed when the selected vertex or edge
was it's self delimiting.
Support using these elements for linked select
as long as they're part of an isolated selection.
Note this only changes cases where the variable was declared inside
the for loop. To handle it outside as well is a different challenge.

While it might be handy to have type-less functionality which is
similar to how C++ math is implemented it can not be easily achieved
with just preprocessor in a way which does not have side-effects on
wrong usage.
There macros where often used on a non-trivial expression, and there
was at least one usage where it was causing an actual side effect/bug
on Windows (see change around square_f(sh[index++]) in studiolight.c).
For such cases it is handy to have a function which is guaranteed to
have zero side-effects. The motivation behind actually removing the
macros is that there is already a way to do similar calculation. Also,
not having such macros is a way to guarantee that its usage is not
changed in a way which have side-effects and that it's not used as an
inspiration for cases where it should not be used.

- Use 'BKE_object_defgroup' prefix for object functions.
- Rename 'defvert_verify_index' to 'defvert_ensure_index'
since this adds the group if it isn't found.
When beveling architectural objects like baseboards or crown mouldings that
may consist of multiple islands, it's useful if the orientation is at least
conistent.
This changes the arbitrary decision of how the orientation should start at a
chain beginning to use the highest side of the profile in the Z direction.

When a vertex between two edges is being collapsed,
it's important that edges between delimiting faces use the
angle between edges without scaling it down.
While faces with different materials wont ever be merged into a single
face, all the detail between the two faces may be removed.
Needed to protect against a case where clamp overlap limited
the offset to approximately zero, and the snap-to-pipe code
would therefore encounter an almost degenerate profile and
fail in matrix inversion.
Profile calculation now happens in a single pass rather than being spread
throughout the process. This means each profile will only be calculated a
single time.

This is a more correct fix to the issue Brecht was fixing in D6600.
While the fix in that patch worked fine for linking it broke ASAN
runtime under some circumstances.
For example, `make full debug developer` would compile, but trying
to start blender will cause assert failure in ASAN (related on check
that ASAN is not running already).
Top-level idea: leave it to CMake to keep track of dependency graph.
The root of the issue comes to the fact that target like "blender" is
configured to use a lot of static libraries coming from Blender sources
and to use external static libraries. There is nothing which ensures
order between blender's and external libraries. Only order of blender
libraries is guaranteed.
It was possible that due to a cycle or other circumstances some of
blender libraries would have been passed to linker after libraries
it uses, causing linker errors.
For example, this order will likely fail:
libbf_blenfont.a libfreetype6.a libbf_blenfont.a
This change makes it so blender libraries are explicitly provided
their dependencies to an external libraries, which allows CMake to
ensure they are always linked against them.
General rule here: if bf_foo depends on an external library it is
to be provided to LIBS for bf_foo.
For example, if bf_blenkernel depends on opensubdiv then LIBS in
blenkernel's CMakeLists.txt is to include OPENSUBDIB_LIBRARIES.
The change is made based on searching for used include folders
such as OPENSUBDIV_INCLUDE_DIRS and adding corresponding libraries
to LIBS ion that CMakeLists.txt. Transitive dependencies are not
simplified by this approach, but I am not aware of any downside of
this: CMake should be smart enough to simplify them on its side.
And even if not, this shouldn't affect linking time.
Benefit of not relying on transitive dependencies is that build
system is more robust towards future changes. For example, if
bf_intern_opensubiv is no longer depends on OPENSUBDIV_LIBRARIES
and all such code is moved to bf_blenkernel this will not break
linking.
The not-so-trivial part is change to blender_add_lib (and its
version in Cycles). The complexity is caused by libraries being
provided as a single list argument which doesn't allow to use
different release and debug libraries on Windows. The idea is:
- Have every library prefixed as "optimized" or "debug" if
separation is needed (non-prefixed libraries will be considered
"generic").
- Loop through libraries passed to function and do simple parsing
which will look for "optimized" and "debug" words and specify
following library to corresponding category.
This isn't something particularly great. Alternative would be to
use target_link_libraries() directly, which sounds like more code
but which is more explicit and allows to have more flexibility
and control comparing to wrapper approach.
Tested the following configurations on Linux, macOS and Windows:
- make full debug developer
- make full release developer
- make lite debug developer
- make lite release developer
NOTE: Linux libraries needs to be compiled with D6641 applied,
otherwise, depending on configuration, it's possible to run into
duplicated zlib symbols error.
