a92ab93c7d Fix T79553: StretchTo constraint: Apply Pose changes bone length
Recompute Rest Length stored in the StretchTo constraint after applying
the current pose as rest pose.

The "Apply Pose as Rest Pose" operator applies the evaluated pose as
rest pose, which means that the change in bone length from the StretchTo
constraint is applied to the rest pose. The bug was caused by the fact
that the StretchTo constraint wasn't updated for the new pose, and thus
still applied the same scale factor to the new pose, effectively
doubling its effect.

The "Apply Pose as Rest Pose" operator now forces a recompute of the
rest length cached in the StretchTo constraint data. As a result, the
length of the bone before and after the pose is applied remains the
same. The X and Z scale (perpendicular to the bone length) are reset to
1.0, as with the applied pose the bone isn't stretched or squashed any
more.

d42530824e Fix T78994: Clear selected pose doesn't work without animation
It looks like the code left this as a todo, but the basic solution is to
add an extra parameter to BKE_bose_rest to check whether bones
are selected before reseting them.

I also corrected the operator description which said it acted on only
selected bones even when there is an option to turn that off. The
"act on selected" is generally implied for Blender's operators anyway.

686ab4c940 T77086 Animation: Passing Dependency Graph to Drivers
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`.

1ca5c8491d Pose paste: avoid auto-keying on unselected bones when 'selection only' is enabled
The `pose_bone_do_paste()` function is documented to only return a
non-NULL pointer on a successful paste, and the one caller that checks
the return value is expecting this behaviour. However, before this
commit, when a valid pose channel was found, 'Selected Only' was
enabled, and the bone was not selected, the function would still return
non-NULL. This resulted in auto-keying pose channels that were not
pasted.

fcf2a712ec Armature: add Inherit Scale options to remove shear or average the scale.
As an inherent property of matrix-based transformation math, non-
uniform scaling of a parent bone induces shear into the transform
matrix of any rotated child. Such matrices cannot be cleanly
decomposed into a combination of location/rotation/scale, which
causes issues for rigging and animation tools.

Blender bones have options to exclude rotation and/or scale from the
inherited transformation, but don't have any support for removing the
often undesired shear component. That goal requires replacing simple
parenting with a combination of multiple bones and constraints. The
same is true about the goal of inheriting some scale, but completely
avoiding shear.

This patch replaces the old Inherit Scale checkbox with a enum that
supports multiple options:

* Full: inherit all effects of scale, like with enabled Inherit Scale.

* Fix Shear: removes shear from the final inherited transformation.

  The cleanup math is specifically designed to preserve the main
  axis of the bone, its length and total volume, and minimally
  affect roll on average. It however will not prevent reappearance
  of shear due to local rotation of the child or its children.

* Average: inherit uniform scale that represents the parent volume.

  This is the simplest foolproof solution that will inherit some
  scale without ever causing shear.

* None: completely remove scale and shear.

* None (Legacy): old disabled Inherit Scale checkbox.

  This mode does not handle parent shear in any way, so the child
  is likely to end up having both scale and shear. It is retained
  for backward compatibility.

Since many rigging-related addons access the use_inherit_scale
property from Python, it is retained as a backward compatibility
stub that provides the old functionality.

As a side effect of reworking the code, this also fixes a matrix
multiplication order bug in the Inherit Rotation code, which caused
the parent local scale to be applied in world space. In rigger
opinion this option is useless in production rigs, so this fix
should not be a problem.

3566b81c8b Refactor access to dependency graph
This change ensures that operators which needs access to evaluated data
first makes sure there is a dependency graph.

Other accesses to the dependency graph made it more explicit about
whether they just need a valid dependency graph pointer or whether they
expect the graph to be already evaluated.

This replaces OPTYPE_USE_EVAL_DATA which is now removed.

Some general rules about usage of accessors:

- Drawing is expected to happen from a fully evaluated dependency graph.
  There is now a function to access it, which will in the future control
  that dependency graph is actually evaluated.

  This check is not yet done because there are some things to be taken
  care about first: for example, post-update hooks might leave scene in
  a state where something is still tagged for update.

- All operators which needs to access evaluated state must use
  CTX_data_ensure_evaluated_depsgraph().

  This function replaces OPTYPE_USE_EVAL_DATA.

  The call is generally to be done in the very beginning of the
  operator, prior other logic (unless this is some comprehensive
  operator which might or might not need access to an evaluated state).

  This call is never to be used from a loop.

  If some utility function requires evaluated state of dependency graph
  the graph is to be passed as an explicit argument. This way it is
  clear that no evaluation happens in a loop or something like this.

- All cases which needs to know dependency graph pointer, but which
  doesn't want to actually evaluate it can use old-style function
  CTX_data_depsgraph_pointer(), assuming that underlying code will
  ensure dependency graph is evaluated prior to accessing it.

- The new functions are replacing OPTYPE_USE_EVAL_DATA, so now it is
  explicit and local about where dependency graph is being ensured.

This commit also contains some fixes of wrong usage of evaluation
functions on original objects. Ideally should be split out, but in
reality with all the APIs being renamed is quite tricky.

Fixes T67454: Blender crash on rapid undo and select

Speculation here is that sometimes undo and selection operators are

0264d8390f Apply Pose as Rest Pose: implement an Only Selected bones option.
The most difficult part is handling parent-child relations correctly:
when a parent is applied, the children should be moved accordingly,
and when applying a child, it should not include transformation from
unapplied parents. All this requires walking bones as a tree, instead
of a flat list.

Limitation: Applying bones with non-uniform scaling without also applying
children will distort non-rest posing on said children for reasons related
to T54159 (basically, non-uniform scale plus rotation creates shear, and
Blender matrix decomposition utilities don't have tools to deal with it).

As far as I can tell, there is no technical reason why the B-Bone
segment thickness scaling can't be separated into two axes. The
only downside is the increase in complexity of the B-Bone settings,
but this is inevitable due to the increase in flexibility.

Updating the file is somewhat complicated though, because F-Curves
and drivers have to be duplicated and updated to the new names.

79312c1912 Depsgraph: Remove duplicated sets of recalc/update flags
There were at least three copies of those:

- OB_RECALC* family of flags, which are rudiment of an old
  dependency graph system.
- PSYS_RECALC* which were used by old dependency graph system
  as a separate set since the graph itself did not handle
  particle systems.
- DEG_TAG_* which was used to tag IDs.

Now there is a single set, which defines what can be tagged
and queried for an update. It also has some aggregate flags
to make queries simpler.

Lets once and for all solve the madness of those flags, stick
to a single set, which will not overlap with anything or require
any extra conversion.

Technically, shouldn't be measurable user difference, but some
of the agregate flags for few dependency graph components did
change.
