The main goal of these changes are to improve static (i.e. build-time)
checks on whether a given data can be allocated and freed with `malloc`
and `free` (C-style), or requires proper C++-style construction and
destruction (`new` and `delete`).
* Add new `MEM_malloc_arrayN_aligned` API.
* Make `MEM_freeN` a template function in C++, which does static assert on
type triviality.
* Add `MEM_SAFE_DELETE`, similar to `MEM_SAFE_FREE` but calling
`MEM_delete`.
The changes to `MEM_freeN` was painful and useful, as it allowed to fix a bunch
of invalid calls in existing codebase already.
It also highlighted a fair amount of places where it is called to free incomplete
type pointers, which is likely a sign of badly designed code (there should
rather be an API to destroy and free these data then, if the data type is not fully
publicly exposed). For now, these are 'worked around' by explicitly casting the
freed pointers to `void *` in these cases - which also makes them easy to search for.
Some of these will be addressed separately (see blender/blender!134765).
Finally, MSVC seems to consider structs defining new/delete operators (e.g. by
using the `MEM_CXX_CLASS_ALLOC_FUNCS` macro) as non-trivial. This does not
seem to follow the definition of type triviality, so for now static type checking in
`MEM_freeN` has been disabled for Windows. We'll likely have to do the same
with type-safe `MEM_[cm]allocN` API being worked on in blender/blender!134771

In the past, around the time that 2.80 was released, 4a08b974f4
introduced the idea of filtering out certain editor changes inside
the paint modes and edit mode (e.g. changing brush sizes in the editor).
This commit is the first in a series to attempt to refine this behavior
so that only certain editor settings are filtered out from the undo
stack.
In total, it does the following:
* Adds the Brush datablock to the list of IDs that do not have undo
pushes.
* Adds support to filter out RNA structs that do not have the
`STRUCT_UNDO` property applied (currently, just the 3D Cursor).
This has the following effects:
* Changing brush settings inside the Image Editor no longer causes
undo pushes, becoming consistent with the other paint modes.
* Changing brush settings while in object mode in the outliner data
block view no longer causes undo pushes.

And replace nullptr arguments for tooltips in UI button
creation functions with std::nullopt. Though the distinction
between "no tooltip" and "empty tooltip" doesn't seem to exist,
it seems safer to keep the distinction since it existed with null before.
Move `Library.runtime` to be a pointer, move the related
`LibraryRuntime` struct to `BKE_library.hh`. Similar to e.g.
Mesh.runtime, that pointer is expected to always be valid, and is
allocated at readtime or when creating a new Library ID.
Related smaller changes:
* Write code now uses standard ID writing codepath for Library IDs too.
* Runtime pointer is reset to nullptr before writing.
* Looking up a library by its absolute path is now handled through a
dedicated utils, `search_filepath_abs`, instead of using
`BLI_findstring`.

This PR adds new RNA properties that deprecate and replace any `sequence` property.
The old prooperties are still there and fully functional, but the description is changed
to indicate that these will be removed in the future and that the new properties should
be used instead.
| Deprecated property | Replacement property |
| --------------------------------- | ----------------------------------- |
| `context.active_sequence_strip` | `context.active_strip` |
| `context.selected_editable_sequences` | `context.selected_editable_strips` |
| `context.selected_sequences` | `context.selected_strips` |
| `context.sequences` | `context.strips` |
| `SequenceEditor.sequences` | `SequenceEditor.strips` |
| `SequenceEditor.sequences_all` | `SequenceEditor.strips_all` |
| `MetaStrip.sequences` | `MetaStrip.strips` |
Previously, rna paths for animation data on strips started with `sequence_editor.sequences`.
This PRadds versioning for the rna paths to make sure to use
the new naming scheme. This does mean that in previous versions of blender,
the animations don't show but the data is not lost (even if the file is saved in the older version).
Also do some cleanup of existing python scripts inside the source to use the
new properties.

When using clangd or running clang-tidy on headers there are
currently many errors. These are noisy in IDEs, make auto fixes
impossible, and break features like code completion, refactoring
and navigation.
This makes source/blender headers work by themselves, which is
generally the goal anyway. But #includes and forward declarations
were often incomplete.
* Add #includes and forward declarations
* Add IWYU pragma: export in a few places
* Remove some unused #includes (but there are many more)
* Tweak ShaderCreateInfo macros to work better with clangd
Some types of headers still have errors, these could be fixed or
worked around with more investigation. Mostly preprocessor
template headers like NOD_static_types.h.
Note that that disabling WITH_UNITY_BUILD is required for clangd to
work properly, otherwise compile_commands.json does not contain
the information for the relevant source files.

This renames the struct `Sequence` to `Strip`.
While the motivation for this partially comes from
the "Sequence Design" #131329, it seems like this
is a good refactor whether the design gets implemented
or not.
The `Sequence` represents what users see as strips in the
VSE. Many places in the code already refere to a `Sequence`
as "strip". It's the C-style "base class" of all strip types.
This also renames the python RNA type `bpy.types.Sequence`
to `bpy.types.Strip` which means that this technically breaks
the python API.

The "Blender" menu contains seven items in "System / "Redraw Timer"
that are for troubleshooting and testing. Six of the items take far
less than a second, but one takes a long time. "Animation Play" times
how long it takes to play through your current animation ten times. But
there is no way to guess this and some users have run it accidentally
by finding it in menu search. It gives no feedback at all, and there
are no hints on how long it will take. Once it plays through your
animation once you might guess that it runs forever. This PR shows
the test name and where it is in its ten runs. On platforms that
support it this also shows an app progress bar (on the taskbar icon for
Windows).

Give the `IDWALK_CB_…` enum an explicit name:
`LibraryForeachIDCallbackFlag`. This way the flags are type-safe, and
it's known where values come from. This is much preferred (at least by
me) to just having `int flags`.
Uses of `0` have been replaced with `IDWALK_CB_NOP` as that has the same
value and is of the right type.
One invalid use of `IDWALK_NOP` was detected by this change, and is
replaced by `IDWALK_CB_NOP`.
This change might be incomplete; I gave the enum a name, fixed the
compiler errors, and then also updated assignments like `int cb_flag =
cb_data->cb_flag`. I might have missed some assignments to `int` though.
No functional changes.

Two commits that basically do the same thing for two `enum`s: give

direction.

----------
I intend to land this PR as its two separate commits. I just put them in the same PR so the buildbot can handle them in one go, and we don't have a stack of highly relatled PRs.
In the future this could also apply to the `IDWALK_RET_…` enum. This one I left out, though, because a proper cleanup there would also have to include their ambiguity on whether they are bitflags (like the enums in this PR) or not. Their values and the code in `BKE_lib_query_foreachid_process()` implies they are bitflags, but in practice they are never or'ed together and just used as discrete values.

In Blender 4.2 in Grease Pencil draw mode it was possible to
erase strokes using box and lasso gestures.
Under the hood, these were just using the selection operators
that had special deletion handling if the object was in draw mode.
Rather than hacking this into the selection operations, this adds
two new operators:
* `grease_pencil.erase_lasso`
* `grease_pencil.erase_box`
When using one of the erase operations with auto-key, the previous
keyframe will be duplicated to the current frame (for the drawings
that are affected by the eraser).
They are mapped to the same shortcuts than the selection
operators in Blender 4.2.
* Lasso erase: `Ctrl`+`Alt`+`RMB`.
* Box erase: `B`.
This is part of #130518.

This commit refactors `BKE_image_load` and `BKE_image_load_exists` APIs:
* Remove the `_ex` versions (the 'exist' boolean return pointer can have
default `nullptr` value instead).
* Add `_in_lib` versions, which match signature and behavior of the
generic ID creation code to allow to find or create a new image ID
directly in a library 'namespace' (as linked data).
This is required by upcommig fixes for Brush Assets, which are using
linked but editable data-blocks.
Fix#130194: When trying to add a new image from the UI (e.g. for a new
texture) for a local ID, if that same exact image was already loaded by
a linked ID, it would trigger an assert in `BKE_id_move_to_same_lib`,
because `BKE_image_load_exists` would return the matching linked Image ID
instead of creating a new local one. In release builds with no assert,
it would result in making a linked ID 'local', while still being used by
original other linked data.
Passing around the intended final destination of the new Image (local or
in a given library) allows `BKE_image_load_exists` to be more specific
when searching for an already loaded matching image ID, and ensures that
a new local Image ID is created in the case described above.

NOTE: This also required some changes to Cycles code itself, who is now

The problem was that the screen space size of the brush was not updated.
This was not fully noticeable because the radius control operator was using

This renames the mode identifiers to be consistent with e.g. the context mode identifiers and other names used for the new Grease Pencil.

* `SCULPT_GPENCIL` -> `SCULPT_GREASE_PENCIL`
* `VERTEX_GPENCIL` -> `VERTEX_GREASE_PENCIL`
* `WEIGHT_GPENCIL` -> `WEIGHT_GREASE_PENCIL`
For the internal `ob->mode` flag:
* `OB_MODE_PAINT_GPENCIL_LEGACY` -> `OB_MODE_PAINT_GREASE_PENCIL`
* `OB_MODE_SCULPT_GPENCIL_LEGACY` -> `OB_MODE_SCULPT_GREASE_PENCIL`

98c92b9033 disabled refreshing for the redo popup, since that requires
passing an operator pointer to the UI to holding on to it while the popup is
visible. Usually operators are short lived and shouldn't be held by the UI, to
avoid dangling pointer accesses. In this case it's fine though, because the
operator will be kept alive in the window manager.
Partially reverts 98c92b9033, and adds a comment to note this special case.

The term "tool" is historic from before the actual tool system got
introduced. Since then the term was already a bit confusing, because it
wasn't directly related to the tool system, but there was still some
relationship between the two. Now brushes and their types are decoupled
much more from the tool system, with a single "Brush" tool supporting
all kinds of brushes (draw, grab, cloth, smooth, ...).
For a more clear terminology, use "brush type" instead of "tool".
For #126032 we need to write the brush type to the asset metadata (done
in !124618), so we can filter brushes based on the type (so the grease
pencil eraser tool only shows eraser brushes, for example). I'd like to
use future proof names for that to avoid versioning of asset metadata in
future, so I'd rather do the full naming change now.
RNA properties (thus BPY names) are not changed for compatibility
reasons. Can be done in 5.0, see blender/blender#124201.

Previously, values for `ID.flag` and `ID.tag` used the prefixes `LIB_` and

related to libraries in general. This patch changes the prefix to `ID_FLAG_` and
`ID_TAG_`. This makes it more obvious what they correspond to, simplifying code.

The RNA path that is generated for Editor properties were mostly
incomplete (e.g. the viewport overlay settings).
- in python tooltips
- from the `Copy (Full) Data Path` operator
- python methods `path_from_id`, `path_resolve` returned incomplete paths
Since a space (editor) is ultimately owned by the screen, we now add the
missing "areas[x].spaces[x]" subpath to any editor.
Nested structs (like the viewport overlay) also need to include this
subpath.
Some editor related structs are not tied to a single space though (and
these cases are therefor not resolved yet):
- Dopesheet is referenced from SpaceGraph, SpaceAction and SpaceNla
- View3DShading is referenced from SpaceView3D but render engines as
well
- FileSelectParams / FileAssetSelectParams / FileAssetSelectIDFilter
need more investigation
NOTE: in case of the VSE, to make this work this also changes the
overlays to be tied to SpaceSeq (the only editor using them)
NOTE: since the above is now in place, adding VSE overlay props to Quick
favourites is now made possible as well (was a leftover from !116604)

Essentially, the issue is that the Adjust Last Operation popup is
created in the new image editor window, before region polling was
executed for the new window. This region polling must be done first
because it can affect which regions are visible, and the
`ARegionType.on_poll_success()` callback may do additional set up.
Now make sure that region polling is always executed when a screen is
prepared for display, as part of the screen "refresh" code.
Note that the region polling is used for the asset shelf regions, which
are supported in the image editor since c60a1006e5.

Previous code would declare properties as `extern PropertyRNA`, but
implement them as type-refined data (e.g. `FloatPropertyRNA`).
This is fully illegal thing, it happened to work 'fine' so far for two
main reasons:
* C-linking does not do type-checks on extern data.
* Code using these publicly exposed data would always use them as
`PorpertyRNA *` pointers, and pass them to RNA API.
However, this (finally !) breaks when trying to move generated
`RNA_property.h` header to C++, since at least MSVC2022 does mangle the
type in the extern'ed symbol name, which makes linking fails epically.
This commit fixes the issue by only declaring `PointerRNA *` pointers in
the headers. These pointers are then defined in each implementation file
(the `rna_xxx_gen.cc` ones), and assinged to the address of a matching
local static variable. These static variables are type-refined, and
actually contain the property definition data.

Turns the asset shelf into a popover which reduces some of the special
handling. An operator `WM_OT_call_asset_shelf_popover()` (similar to
`WM_OT_call_panel()`) is added to be able to call the popover from shortcuts.
Exactly this was an important aspect for the brush assets project, to allow
quick searching for brushes from the popup.
A custom shortcut can be added to asset shelf popovers using "Assign Shortcut"
in the context menu of buttons invoking it.
The popover is spawned with the mouse hovering the first asset and the search
button active using "semi modal" handling. That means while the popover is
open, any text input is captured by the search button, while the rest of the
popover stays interactive. So for example navigating through asset catalogs is
possible, a single click activates an asset and closes the popover.
Reviewed as part of the asset shelf project, see:

This makes it possible for popups to have their confirm & cancel buttons
defined in the operator's draw callback.
When used with popups created by: `WindowManager::invoke_props_dialog()`
to override the default confirm/cancel buttons.
In the case of `WindowManager::popover(..)` & `bpy.ops.wm.call_panel()`
this can be used to add confirm/cancel buttons.
Details:
- When the confirm or cancel text argument is a blank string the button
isn't shown, making it possible to only show a single button.
- The template is similar to UILayout::operator in that it returns the
operator properties for the confirm action.
- MS-Windows alternate ordering of Confirm/Cancel is followed.
