Functions `mesh_create_eval_final_view()` and
`mesh_create_eval_final_render()` were doing the exact same thing,
except for a hack introduced in d3eb9dddd6 (2012-10-08, Better fix for
T32846: dupligroup messes up particle instancing on rendering) that
appears to be no longer necessary. Besides that, these functions had
confusing names. Their functionality changed over time, and whether to
do for-render or for-viewport evaluation is now actually determined by
the depsgraph evaluation mode. This means that the `..._render` function
could evaluate a mesh with viewport settings, and vice versa.
The functions are now merged into `mesh_create_eval_final()`, and the
hack has been removed. The `OB_NO_PSYS_UPDATE` flag has been removed
entirely (instead of keeping it around as deprecated flag), because it
was always only temporarily set on objects during mesh evaluation and
thus not saved to the blend file.
No expected functional changes as far as users are concerned.
It is unfortunate that we cannot get active modifier from context when
operator is called from a shortcut, but we'd need an event for this to
work... So for now forbid any modifier operation of liboverride objects
in that case.
This addresses warnings from Clang-Tidy's `readability-else-after-return`
rule in the `source/blender/blenlib` module. Not all warnings are
addressed in this commit.
No functional changes.
Following work done in 2.83, the resolution control is now a real
level-of-detail parameter. It is now useful to be able to set the
resolution for display independently from render. This is true for
both mesh generation and mesh deformation modes.
For compatibility with old scenes, resolution is retained and is the
render resolution. Old modifiers loaded have the value of resolution
also applied to viewport resolution. This allows newer modifiers to
be used in older versions without trouble

Custom driver functions need access to the dependency graph that is
triggering the evaluation of the driver. This patch passes the
dependency graph pointer through all the animation-related calls.
Instead of passing the evaluation time to functions, the code now passes
an `AnimationEvalContext` pointer:
```
typedef struct AnimationEvalContext {
struct Depsgraph *const depsgraph;
const float eval_time;
} AnimationEvalContext;
```
These structs are read-only, meaning that the code cannot change the
evaluation time. Note that the `depsgraph` pointer itself is const, but
it points to a non-const depsgraph.
FCurves and Drivers can be evaluated at a different time than the
current scene time, for example when evaluating NLA strips. This means
that, even though the current time is stored in the dependency graph, we
need an explicit evaluation time.
There are two functions that allow creation of `AnimationEvalContext`
objects:
- `BKE_animsys_eval_context_construct(Depsgraph *depsgraph, float
eval_time)`, which creates a new context object from scratch, and
- `BKE_animsys_eval_context_construct_at(AnimationEvalContext
*anim_eval_context, float eval_time)`, which can be used to create a
`AnimationEvalContext` with the same depsgraph, but at a different
time. This makes it possible to later add fields without changing any
of the code that just want to change the eval time.
This also provides a fix for T75553, although it does require a change
to the custom driver function. The driver should call
`custom_function(depsgraph)`, and the function should use that depsgraph
instead of information from `bpy.context`.

Duplication and deletion code of modifiers was totally wrong for
particle system, that special weird thing needs its own custom
management.
Note that for now I chose not to duplicate the particle settings ID when
duplicating the modifier...
This can be useful to save the result of a cloth simulation as a
shape key without destroying the simulation, so it's possible to
e.g. re-run it to get other shapes, or simply use the new shape
key to start the simulation already in a draped state.
It also makes sense to allow applying as shape key even when the
mesh is shared, because the operation itself just adds a shape
key. To support this, split the apply operator into Apply and
Apply As Shapekey so that they can have different poll callbacks.

See rB1fa40c9f8a81 for more details. The implementation is the same.
The only difference to the mesh modifier commit is a slight rework of
edit_modifier_invoke_properties in order to pass through to check for
other keymap items with the same shortcut.
The shortcuts act on the modifier with its panel under the mouse.
The following shortcuts are enabled by default:
- Remove modifier: X, Delete
- Apply modifier: Ctrl A
- Duplicate modifier: Shift D
More shortcuts can be added in the keymap.
Each panel can now store a custom data RNA pointer, and a new
function is added to get the custom data for the panel under the
cursor. This custom data could be used to refactor the "List Panel
System" to generalize it and integrate it further with RNA.
The same functionality will be added in further commits where it
applies to constraints, grease pencil modifiers, and effects.

This patch implements the list panel system D7490 for modifiers.
It also moves modifier drawing to a callback in ModifierTypeInfo
in line with the extensible architecture refactoring goal T75724.
This adds a PanelRegister callback and utilities for registering
panels and subpanels. It also adds the callbacks for expansion saving
and drag and drop reordering described in D7490.
These utilities, callbacks, and other common UI elements shared
between modifiers live in MOD_ui_common.c.
Because modifier buttons are now in panels, we can make use of
subpanels for organization. The UI layouts also use the single
column layout style consistently used elsewhere in Blender.
Additionally, the mode-setting buttons are aligned and ordered
consistently with the outliner.
However, the large number of UI changes in this patch may mean
that additional polishing is required in master.
Thanks to William Reynish (@billreynish) who did a fair amount of the
layout work and to Julian Eisel (@Severin) for consistent help.

The fix was actually missing few bits:
- Firstly, the operator itself is not to do UNDO push
- Secondly, multires sculpt/top level are not pushed to the undo
node, so undo can not happen reliably.
It should be possible to incorporate some of the work from WIP patch
for propagation undo, but it needs more work.
Reverting code base to the previous state, since currently things
are actually a bit more confusing then they used to be.
This reverts commit 0c928087a3.
This introduces two alternative subdivision modes that generates
displacement on the grids that look as Simple subdivisions but while
using the Catmull-Clark subdivision type in the modifier. This way,
Simple and Catmull-Clark subdivision can be combined when creating new
levels if needed, for example, to sculpt hard surface objects.
Subdivide simple smooths the sculpted data when creating a new
subdivision level. Subdivide linear also preserves the sharpness
in the sculpted data.

This implements the main unsubdivide algorithm which rebuilds a base mesh and extracts the grid's data from a high resolution mesh.
It includes the Rebuild Subdivisions operator, which generates all subdivision levels down to the level 0 base mesh.
It supports:
- Rebuilding an arbitrary number of levels (Unsubdivide) or as many levels as possible down to level 0 in a single step (Rebuild Subdivisions).
- Rebuilding with already existing grids.
- Meshes with n-gons and triangles
- Meshes with more than 2 faces per edge
- Base mesh made completely out of triangles
- Meshes without poles
- Meshes with multiple disconnected elements at the same subdivision level

The idea is to push both base mesh geometry and PBVH coordinates
so it is possible to undo everything without loosing data which was
not flushed from sculpt session to base mesh.
It is possible do memory optimization to avoid push custom data
layers which are not touched by operator, but before doing that
better to ensure this is a correct and working approach.

This change fixes artifacts produced by these operations.
On a technical aspect this is done by porting all of the operations
to the new subdivision surface implementation which ensures that
tangent space used to evaluate modifier and those operations is
exactly the same (before modifier will use new code and the operations
will still use an old one).
The next step is to get sculpting on a non-top level to work, and
that actually requires fixes in the undo system.
Also cleaned up code there, making a proper poll function for the apply
modifier operator, that way button is properly disabled in UI itself in
most invalid situations.
This data is only used to get current time/frame value, which is never
mandatory to add a modifier.
Needed by incoming fix to support particles modifiers in liboverrides.
Previously the cache for the modifier would not be invalidated if
modifier settings were changed with drivers or keyframes.
Now we compare the current setting with the ones used to generate the
cache and invalidate the cache if they differ.

Make a distinction between flush sculpt changes for rendering, and forcing
sculpt data structures to be rebuilt after mesh changes. Also don't use PBVH
for renders.
The old layout of `PointerRNA` was confusing for historic reasons:
```
typedef struct PointerRNA {
struct {
void *data;
} id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
This patch updates it to:
```
typedef struct PointerRNA {
struct ID *owner_id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
Throughout the code base `id.data` was replaced with `owner_id`.
Furthermore, many explicit pointer type casts were added which
were implicit before. Some type casts to `ID *` were removed.
