Ref D14069
As part of the project of converting `MVert` into `float3`
(more details in T93602), this is an easy step, since it
is only locally used runtime data. In the six places it was
used, the flag was replaced by a local bitmap.
By itself this change has no benefits other than making some
code slightly simpler. It only really matters when the other
flags are removed and it can be removed from `MVert`
along with the bevel weight.

Allows to perform correction of coordinate delta/displacement in a
similar way of how sculpt mode handles sculpting on a deformed mesh.
An example of usecase of this is allowing riggers and sciprters to
improve corrective shapekey workflow.
The usage consists of pre-processing and access. For example:
object.crazyspace_eval(depsgraph, scene)
# When we have a difference between two vertices and want to convert
# it to a space to be stored, say, in shapekey:
delta_in_orig_space = rigged_ob.crazyspace_displacement_to_original(
vertex_index=i, displacement=delta)
# The reverse of above.
delta_in_deformed_space = rigged_ob.crazyspace_displacement_to_deformed(
vertex_index=i, displacement=delta)
object.crazyspace_eval_clear()

The evaluated mesh is a result of evaluated modifiers, and referencing
other evaluated IDs such as materials.
It can not be stored in the EditMesh structure which is intended to be
re-used by many areas. Such sharing was causing ownership errors causing
bugs like
T93855: Cycles crash with edit mode and simultaneous viewport and final render
The proposed solution is to store the evaluated edit mesh and its cage in
the object's runtime field. The motivation goes as following:
- It allows to avoid ownership problems like the ones in the linked report.
- Object level is chosen over mesh level is because the evaluated mesh
is affected by modifiers, which are on the object level.
This patch allows to have modifier stack of an object which shares mesh with
an object which is in edit mode to be properly taken into account (before
the change the modifier stack from the active object will be used for all
objects which share the mesh).
There is a change in the way how copy-on-write is handled in the edit mode to
allow proper state update when changing active scene (or having two windows
with different scenes). Previously, the copt-on-write would have been ignored
by skipping tagging CoW component. Now it is ignored from within the CoW
operation callback. This allows to update edit pointers for objects which are
not from the current depsgraph and where the edit_mesh was never assigned in
the case when the depsgraph was evaluated prior the active depsgraph.
There is no user level changes changes expected with the CoW handling changes:
should not affect on neither performance, nor memory consumption.
Tested scenarios:
- Various modifiers configurations of objects sharing mesh and be part of the
same scene.
- Steps from the reports: T93855, T82952, T77359
This also fixes T76609, T72733 and perhaps other reports.

Ref T92709
This resolves a performance regression in 2.8x where every edit-mode
update performed an edit-mesh to mesh conversion.
Now the conversion will be lazily initialized if/when it's required.
New BKE_mesh_wrapper_* functions abstract over mesh data access.
Currently only edit-mesh and regular meshes are supported.
In the future sub-surface meshes may be supported too.

The function `modifiers_disable_subsurf_temporary` disables
temporarily only subsurf modifiers with the `On Cage` option enabled.
But a modifier can act on cage even with this option disabled.
Differential Revision: https://developer.blender.org/D6722
This is a revert of a small fraction of commit rB5e332fd700
that introduced the issue according to bisect.
Doing a break here is wrong, because BKE_crazyspace_build_sculpt
assumes that processing stopped at the first deform modifier
without deformMatrices, and thus skips all modifiers until it
finds one like that. Thus this early loop exit makes the behavior
worse, as instead of skipping just Mask and Mirror, it skips all.
The issue was caused by crazy space distortion orientation happening
for subsurf modifier.
Solved by making it so subsurf only deforms the surface but keeps
matrices as-is. This is not fully mathematically correct, but is better
that the fall-back solution which was doing wrong matrices anyway.
Also, this is closer to have subsurf was handled prior to the
related changes.

Modifier stack evaluation would copy mesh settings other than mesh topology
automatically, outside of the individual modifier evaluation. This leads to hard
to understand code, and makes it unclear which settings are available in following
modifiers, and which only after the entire stack is evaluated.
Now every modifier is responsible to ensure the mesh it outputs preserves materials,
texture space and other settings, or alters them as needed.

This is a regression since PBVH was introduced for weight paint.
The solution is: treat subsurf and multires modifiers as deforming
ones for the weight painting. This is an easiest solution to make
PBVH use subdivided location of original vertices.
This change could simplify some of the weight paint by removing
the grids check, since PBVH is not supposed to be built from grids
in this case anymore.

Need to use original mesh to get virtual modifiers list, otherwise
key datablocks will not be properly taken into account (since evaluated
mesh doesn't have key datablock).
We already have different storages for cddata of verts, edges etc.,
'simply' do the same for the mask flags we use all around Blender code
to request some data, or limit some operation to some layers, etc.
Reason we need this is that some cddata types (like Normals) are
actually shared between verts/polys/loops, and we don’t want to generate
clnors everytime we request vnors!
As a side note, this also does final fix to T59338, which was the
trigger for this patch (need to request computed loop normals for
another mesh than evaluated one).

Was initially reported when painting on a mesh with armature,
which was failing due to missing bbone cache. The issue was
deeper, and was related on the way which object was used to
