Currently each node's position is stored in the coordinate space of
its parent. To find the location of a node on the canvas, we have to
apply the translation of each of its parents. Also, nodes have hidden
"offset" values used while transforming frame nodes. Together,
those made the system much more complicated than necessary,
and they made the Python API ineffective.
This commit removes usage of the offset values and moves nodes
to be stored in the "global" space of the node canvas. It also resolves
some weird behavior when resizing frame nodes, and fixes a few bugs.
The change is forward compatible, so we still write files with nodes in
the old parent-space format. In 5.0 the conversion when writing can be
removed. The existing Python API also stays the same. A new
"location_absolute" property gives node locations in global space,
and changing the old property also moves the child nodes of frames.
Resolves#92458, #72904.

Edit mode for curves and Grease Pencil was using the plain object transform for
all points without support for individual crazyspace transforms. This patch adds
support for the local rotation matrices, so editing curves on top of modifiers
converts offsets into original geometry space.
For Curves objects these matrices are currently only computed by the surface
deformation node, so editing on top of a surface deformation is the only case
that works currently.
For Grease Pencil the armature modifier is supported and more should be added
in future (see overview task #131599).

For a bit of (somewhat related) history, check 8d590e4b86.
The real problem here is that for non square images, the
`applyAspectRatio` works with "wrong" vectors if translation constraints
(`CON_APPLY`) are used. Then, the passed vector might actually have axis
changed, e.g. constraining to the Y axis does not hold the Y translation
value in dvec[1], but in dvec[0]. This is expected by design, but
`applyAspectRatio` is not aware of this and does wrong things.
The easy way around this is to actually call `applyAspectRatio` before
the `CON_APPLY` stuff takes place.
NOTE: future improvement might be to split (or rename)
`removeAspectRatio` / `applyAspectRatio` becaues these functions also
handle the "conversion" to pixel values which is not obvious atm.

Proportional editing expects `IndexMask` from all Bezier points not only from selection as it affects not only selected curves.
Therefore `selected_editable_strokes` changed `editable_strokes` and initialized with `retrieve_editable_strokes`.

Mutliframe editing wasn't using the falloff.
The fix adds a new field `Vector<float> grease_pencil_falloffs` to
`struct CurvesTransformData`. References it's values with `TransData.extra`.

Grease Pencil animation data is stored in the object-data, not the
`AnimData` of the Grease Pencil ID. This meant that the object was
not properly tagged for an update, because the code assumed that
the object had an `adt`.
The fix calls `ANIM_id_update` to directly tag the Grease Pencil
ID for an update (which will also update the Grease Pencil frames
animation data).
Avoid rebuilding BVH trees when meshes are copied.
Similar to the other uses of the shared cache system,
this can arbitrarily improve performance when meshes
are copied but not deformed and BVH building is the
main bottleneck. In a simple test file I got a 6x speedup.
The amount of code is also reduced and the system is
much simpler overall-- built out of common threading
patterns like `SharedCache` with its double-checked lock.
RAII is used in a few places to simplify memory management
too.
The downside is storing more `SharedCache` items in the
mesh runtime struct. That has a slight cost when copying
a small mesh many times, but we have ideas to improve that
in the future anyway (#104327).

Oversight in 09d2108bf5
For one, numinput for keyframes would be broken unless the mouse is moved first.
Secondly, redo would also be broken (using the `Adjust Last Operation` panel or the `Repeat Last` operator).
Above commit did a check for `TRANS_RUNNING` before calling `grease_pencil_layer_update_trans_data`.
This isnt set in any of the above scenarios (it only gets set once the moues moves).
This PR removes `TRANS_RUNNING` check to have proper calls to `grease_pencil_layer_update_trans_data`.
It has one downside: you now get a `grease_pencil_layer_update_trans_data` as soon as you hit `G`.
So it does remove_frame / add_frame unnecessarily (since we are still on the same frame), but only once, sees harmless in comparison to the two regression it fixes.

These are useless now that PointerRNA has explicit default values, and
become a problem when real constructors are added to this struct. Simply
use the default empty value initialization instead.

Compositor: UI: remove snapping to nodes.
Snapping nodes to other nodes behaves in a very unpredictable way, which makes most snapping options useless.
The patch removes the following:
- Snapping options `Node X`, `Node Y` and `Node XY`
- Menu `Snap Node Element`
- Menu `Snap Target`
New behavior:
- Activating `Snap` always acts as 'Snap to Grid'

The root cause of this bug can be traced to:
- `ANIM_nla_mapping_get(ac, ale)` conditionally returns an `AnimData *adt`.
- This can be `nullptr` in various cases, depending on the editor (in `ac`) and
the type & source of data (in `ale`).
- This `nullptr` has different meanings:
1. There is not enough information to return an `adt` (like `ac` or `ale`
being `nullptr` themselves).
2. NLA time remapping should not be done. For example for NLA control F-Curves
(like animated strip influence), or Grease Pencil (because that doesn't use
the NLA).
- The above-returned `adt` is passed to other functions. Some of them are aware
of the "`nullptr` means no NLA time remapping" scenario, and gracefully handle
it. Other code, however, just gets "an adt" from the caller and handles it as
normal (and likely crashes on `nullptr`). Other cases start out as the first,
but somewhere in the call stack shift over to the second.
The approach taken in this PR to fix the bug is to (generally) stop signaling
"do not use NLA time remapping" via `adt = nullptr`, and instead explicitly
indicate/check whether remapping should be done.
In most cases this means passing a `bAnimListElem *` instead of an `AnimData *`,
because the former has the information needed to determine if time remapping
should be done or not. However, in some cases there is no `bAnimListElem *` to
pass, and instead other information determines whether remapping is needed. In
those cases we add a `bool` parameter or field in the appropriate place so that
calling code can explicitly indicate whether remapping should be done or not.
To accomplish this a variety of functions have been added to help handle things
correctly. Of particular note:
- `AnimData *ANIM_nla_mapping_get(ac, ale)` (that conditionally returned an
`adt`) has been removed entirely in favor of the new
`bool ANIM_nla_mapping_allowed(ale)` function that simply returns whether
nla remapping should be done or not.
- `ANIM_nla_tweakedit_remap(ale, …)` has been added, which wraps
`BKE_nla_tweakedit_remap(adt, …)` and only performs the remapping when
`ANIM_nla_mapping_allowed()` indicates that it's allowed.
- `ANIM_nla_mapping_apply_if_needed_fcurve(ale, …)` has been added, which is an
alternative to `ANIM_nla_mapping_apply_fcurve(adt, …)` that also only performs
the remapping when `ANIM_nla_mapping_allowed()` indicates that it's allowed.
Note that even with this PR there are still a couple of places remaining that
use `adt = nullptr` to indicate "don't remap", because they appear to be correct
and would require larger changes to make explicit. In those cases comments have
been added to explain the situation, with a reference to this PR. In the future
we way want to take the time to change those as well.
Also of minor note: this PR moves the definition of the type `slot_handle_t`
from ANIM_action.hh to BKE_action.hh. This is due to `BKE_nla.hh` (which needs
that definition) now being included directly and indirectly in a lot more
places. Moving the definition to BKE_action.hh prevents all of those new places
from gaining dependencies on the animrig module.

The `fmt::format` can process the format string at compile time. Currently, we
don't seem to be using that as we don't use `FMT_STRING`. Starting with C++20,
that will be the default though, and one has to explicitly opt out in places
where the string is not known at compile time using `fmt::runtime(...)`.
Currently, our code does not compile as C++20 because of that. Unfortunately, we
have many places with runtime format strings, because of i18n.

This member was only really used by `transform_convert_object.cc` and
`transform_convert_object_texspace.cc`.
So instead of using a super-specialized member, use `TransData::extra`
instead.
This implements the proposal from #124512. For that it contains the following
changes:
* Remove the global override of `new`/`delete` when `WITH_CXX_GUARDEDALLOC` was
enabled.
* Always use `MEM_CXX_CLASS_ALLOC_FUNCS` where it is currently used. This used
to be guarded by `WITH_CXX_GUARDEDALLOC` in some but not all cases. This means
that a few classes which didn't use our guarded allocator by default before,
are now using it.

NOTE: This also required some changes to Cycles code itself, who is now
directly including `BKE_image.hh` instead of declaring a few prototypes
of these functions in its `blender/utils.h` header (due to C++ functions
names mangling, this was not working anymore).

Add some missing `nullptr` and `ale->type` checks to ensure the
assmptions the rest of the code makes holds.
The direct cause of this issue is likely
822907a68d. The root cause is the hard to
predict behaviour of the animation filtering system combined with a lot
of pointer casts without testing whether the data is actually of the
expected type.

The snap cursor internally snaps to the Face to define the occlusion of
the Grid or to calculate the "Surface" orientation set by the tool.
Even though this is not the snap point enabled by the user, this
internal Snap to Face takes precedence over the Snap to Grid that is
enabled by the user.
To solve this, the solution is to do a second snap test but now only to
Grid and using the hit point as a reference for the closest grid.
Also fixes Absolute Increment Snap not being detected as Grid by the
tool.
