Only do `next++` if `next` is a non-`NULL` pointer. This doesn't change
the functionality of the code, but it does prevent a sanitizer warning.
No functional changes.
Improve 3D text selection & feedback when moving the mouse outside of
the text. Previously mouse selection only worked if the mouse was over
the text, now there is more margin to select characters or lines.

Add an offset indices utility to do fill constant size new offsets in
parallel, which was already done in the duplicate elements node.
For example, filling poly offsets for a new part of a mesh that is only
quads. In the extrude node this was single-threaded before, so the
new poly offsets is about 10x faster, saving about 10 out of 157 ms
when extruding 2 million faces.
This moves the following `editors/*` directories to C++:
- animation, armature, lattice, mesh, metaball, object, scene.
Much of the changes in this commit (inserting casts in particular)
was automated. Further changes like switching to functional style
casts can be done separately by existing automated scripts.

It was only used by OpenEXR and Iris images, and saving the Z Buffer
in those formats was disabled by default. This option comes from the
times prior to the addition of the Multilayer EXR.
It also worth noting that it was not possible to save Iris with Depth
pass from Blender as internally it is called IRIZ format and it was
not exposed. But even after exposing this format option something still
was missing as saving and loading ITIZ did not show up the Depth pass.
The reason of removal is to make it a more clear match of the ImBuf
with a render pass, and use it instead of a custom type in the render
result and render pass API. This will simplify the API and also avoid
stealing buffers and making shallow copies when showing the render
result.
For the cases when Depth is needed a Multilayer EXR is to be used,
as most likely more than just the Depth will be needed.
On a user level this change:
- Removes the "Z Buffer" option from the interface.
- It preserves existing sockets in compositor nodes, but it will
output black image. Also changing the image data-block will
remove the socket unless a Multilayer EXR with Depth pass image
is selected.
- Removes "Depth" socket of the Viewer and Composite nodes.

Adds a new function to insert a frame with a duration on a layer.
Also adds tests for the edge cases.
This introduces the concept of a `null-frame`.
It can be created with `GreasePencilFrame::null()` and checked for with
`is_null()`.
The purpose of a `null` frame is to indicate the end of whatever frame
comes before it. This way, the frames map does not need to store
the duration of frames. The duration is always implied by the distance
to the next frame.
Split much of BKE_pbvh.h into BKE_pbvh_api.hh.
BKE_pbvh.h is included by BKE_paint.h, which in
turn is included by large amounts of code including
RNA.
This makes it extremely difficult to change
or clean up the PBVH API, since each modification
of BKE_pbvh.h can take 20-30 minutes to compile,
even on a quad-core system with an SSD. This
commit fixes that by moving most of BKE_pbvh.h
into another file and just having the core,
external-facing interfaces in BKE_pbvh.h.
String search & replace is a higher level function (unlike BLI_string.h)
which handlers lower level replacements for printing and string copying.
Also use BLI_string_* prefix (matching other utilities).
This makes it possible to use BLI_string in Blender's internal utilities
without depending on DynStr, MemArena... etc.
This utility counts the number of occurrences of each index in an array.
This is used for building mesh topology maps offsets, or for counting
the number of connected elements. Some users are geometry nodes,
the subdivision draw cache, and mesh to curve conversion.
See #109628
After some recent changes BLI_math_base got (indirectly) included
from DNA file, causing defines conflict in Cycles: Cycles wants the
default fast behavior of square root, and BLI color wants it to be
more preciese.
Proposed solution is to move the SSE block away from the math_base
closer to code which uses it. The initial intent was to make those
functions reusable, but for a long long time the color utilities
are the only users of those functions.
This change does not prevent the error from re-occurring in the
future if some code includes sse2neon and BLI color utilities, but
it makes such conflict situation much less likely to happen, for
now.
The downside of this change is that the code now need to include
BLI_simd.h explicitly to access BLI_HAVE_SSE2 instead of relying
on it being included indirectly with math headers. The mitigation
for this is to change semantic of the BLI_HAVE_SSE2: now it is
defined to 1 if SSE2 is supported and to 0 otherwise. This makes
it so the code needs to check if using `#if BLI_HAVE_SSE2` and
if the BLI_simd.h is not included it will generate warning when
using GCC or Clang.
This change in semantic is is something the current patches would
need to ensure is handled correctly.

Format the prefix once, then prepend it using a function shared between
BKE_report_prependf & BKE_report_prepend.
Replace BLI_dynstr with BLI_vsprintfN for string formatting.
On my system `int(PIL_check_seconds_timer() * 1000000.0)` always game
the same result because the double value was out of the int range.
Use PIL_check_seconds_timer_i instead (as is done elsewhere).
Replace `typedef struct X {} X;` with `struct X {};`
In some cases the first and last name didn't match although this
is rarely useful, even a typo in some cases, e.g. TrachPathPoint.
The simulation state used by simulation nodes is owned by the modifier. Since a
geometry nodes setup can contain an arbitrary number of simulations, the modifier
has a mapping from `SimulationZoneID` to `SimulationZoneState`. This patch changes
what is used as `SimulationZoneID`.
Previously, the `SimulationZoneID` contained a list of `bNode::identifier` that described
the path from the root node tree to the simulation output node. This works ok in many
cases, but also has a significant problem: The `SimulationZoneID` changes when moving
the simulation zone into or out of a node group. This implies that any of these operations
loses the mapping from zone to simulation state, invalidating the cache or even baked data.
The goal of this patch is to introduce a single-integer ID that identifies a (nested) simulation
zone and is stable even when grouping and un-grouping. The ID should be stable even if the
node group containing the (nested) simulation zone is in a separate linked .blend file and
that linked file is changed.
In the future, the same kind of ID can be used to store e.g. checkpoint/baked/frozen data
in the modifier.
To achieve the described goal, node trees can now store an arbitrary number of nested node
references (an array of `bNestedNodeRef`). Each nested node reference has an ID that is
unique within the current node tree. The node tree does not store the entire path to the
nested node. Instead it only know which group node the nested node is in, and what the
nested node ID of the node is within that group. Grouping and un-grouping operations
have to update the nested node references to keep the IDs stable. Importantly though,
these operations only have to care about the two node groups that are affected. IDs in
higher level node groups remain unchanged by design.
A consequence of this design is that every `bNodeTree` now has a `bNestedNodeRef`
for every (nested) simulation zone. Two instances of the same simulation zone (because
a node group is reused) are referenced by two separate `bNestedNodeRef`. This is
important to keep in mind, because it also means that this solution doesn't scale well if
we wanted to use it to keep stable references to *all* nested nodes. I can't think of a
solution that fulfills the described requirements but scales better with more nodes. For
that reason, this solution should only be used when we want to store data for each
referenced nested node at the top level (like we do for simulations).
This is not a replacement for `ViewerPath` which can store a path to data in a node tree
without changing the node tree. Also `ViewerPath` can contain information like the loop
iteration that should be viewed (#109164). `bNestedNodeRef` can't differentiate between
different iterations of a loop. This also means that simulations can't be used inside of a
loop (loops inside of a simulation work fine though).
When baking, the new stable ID is now written to disk, which means that baked data is
not invalidated by grouping/un-grouping operations. Backward compatibility for baked
data is provided, but only works as long as the simulation zone has not been moved to
a different node group yet. Forward compatibility for the baked data is not provided
(so older versions can't load the data baked with a newer version of Blender).

We can't take the ownership of the data of a CustomDataLayer by simply
swapping the pointers anymore, since the data is owned by the layer's
implicit sharing info. Since shape keys don't support implicit sharing
(yet?), just duplicate the layer data instead of taking ownership of it.
There is no need to pass `BVHTreeFromEditMesh` userdata if only
`BMEditMesh` is used in the callbacks.
And this code is only used in the snap system, with this change the
snap code is more simplified and organized.
Small inconsistency leftover from ebb5643e59, 32bbfbb06e and 7ef8389dad
commits.
Weirdly enough that was not a problem on Linux X11, but did cause
issues at leaast on Windows and Linux Wayland.
Also see #103343.
There was one unusual complication due to `openvdb` here. The `BKE_volume.h`
header included `openvdb` but that would not link correctly in rna code. I'm not entirely
sure why any of the openvdb code is actually instantiated, may be an issue in the
`openvdb` headers. The solution is to create a new header that gives access to the
underlying `openvdb` data structure for a `Volume` geometry. This header can't be
included in rna for now, until the linking issues are resolved.

Similar to 5f16e24cc9, this adds support for edit mode
to the point cloud object type, which is currently hidden behind an
experimental option. No interaction is possible yet, for now this
can be used as a testing for a node-group-operator-only mode.
`CD_HAIRLENGTH` is not really a custom data type, it was just used to
specify the hair particle "length" attribute to pass it to EEVEE and
material preview. Because of the "typemap" array in `CustomData`,
it's better not to have this unnecessary type. Instead, use the same
mechanism used to request the active color attribute.
