When using a tablet an increased gizmo hit-radius was used,
afterwards toggling modifier keys could then re-evaluate the
highlighted gizmo with a smaller radius, meaning that pressing modifiers
caused gizmos to become inactive.
Revert [0] while keeping larger radius for both mouse & tablet motion
from 10 to 12 px (scaled by the UI scale).

Previously spell checker ignored text in single quotes however this
meant incorrect spelling was ignored in text where it shouldn't have
been.
In cases single quotes were used for literal strings
(such as variables, code & compiler flags),
replace these with back-ticks.
In cases they were used for UI labels,
replace these with double quotes.
In cases they were used to reference symbols,
replace them with doxygens symbol link syntax (leading hash).
Apply some spelling corrections & tweaks (for check_spelling_* targets).
Recent commits ([0], [1]) referenced the last handled event
which is incorrect.
- It represents the previous event (not the event being handled).
- It's documented to only be used by the event queue logic.
Resolve using the current event instead of the last handled.

It's safer to pass a type so that it can be checked if delete should be
used instead. Also changes a few void pointer casts to const_cast so that
if the data becomes typed it's an error.

Gizmos that contain 3D parts, like the rounded lines of the "Rotate"
gizmo, have a fairly small hit size that make it hard to grab with a
tablet pen. This PR just increases the radius around the pointer
position while using a pen.

Failure to refresh the highlighted gizmo meant that clicking
on a highlighted gizmo would attempt to activate it even though
it's poll function failed - which crashed in this case.
Resolve the common-case by ensuring a call to refresh the gizmo-map
causes the event system to re-evaluate the highlighted gizmo,
even if the cursor doesn't move.
Since it's still possible the call to "refresh" the gizmo is missed,
gizmo_tweak_invoke now checks the gizmo-groups poll succeeds with an
assert and early return if it doesn't. This would have prevented the
crash although the highlighted-gizmo still won't be reset - causing
the cursor to display as if it's over a gizmo until it's moved.
GPU_DEPTH_NONE leads to issues with Intel GPU drivers on Windows
where camera gizmos cannot be shifted. glGetQueryObjectuiv for
GL_SAMPLES_PASSED seems to return zero in all cases.
This might be due to undefined behavior of OpenGL when the depth
test is disabled and rendering to a depth render target-only
framebuffer. Using GPU_DEPTH_ALWAYS fixes the issue.

- Manually check over all direct calls to operator callbacks
ensuring the result isn't assigned to an int.
- OPERATOR_RETVAL_CHECK() now fails unless a wmOperatorStatus is used.
- Check the return values of direct calls to callbacks.
- Remove invalid check for the return value of rna_operator_check_cb.
- Use the variable name `retval` as it's most widely used.
- Move the assignment of `retval` out of the `if` statement in
sculpt/paint operators because it prevents assigning the result
`const` variable.
Callbacks: exec invoke & modal now use a typed enum wmOperatorStatus.
This helps avoid mistakes returning incompatible booleans or other
values which don't make sense for operators to return.
It also makes it more obvious functions in the WM API are intended
to be used to calculate return values for operator callbacks.
Operator enums have been moved into DNA_windowmanager_enums.h
so this can be used in other headers without loading other includes
indirectly.
No functional changes expected.
Ref !136227
The main issue of 'type-less' standard C allocations is that there is no check on
allocated type possible.
This is a serious source of annoyance (and crashes) when making some
low-level structs non-trivial, as tracking down all usages of these
structs in higher-level other structs and their allocation is... really
painful.
MEM_[cm]allocN<T> templates on the other hand do check that the
given type is trivial, at build time (static assert), which makes such issue...
trivial to catch.
NOTE: New code should strive to use MEM_new (i.e. allocation and
construction) as much as possible, even for trivial PoD types.
Pull Request: https://projects.blender.org/blender/blender/pulls/135626
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

Previously, the global storage of these types either used a GHash or a
blender::Map. VectorSet is preferrable to GHash because it's type safe,
clearer, and faster. It's preferrable to Map because the key doesn't
have to be duplicated and because iteration is faster.
This PR moves these registered types to VectorSet, just like the
node, node socket, and node tree types. Note that none of these types
use RAII for allocation, so freeing is still done manually.
Testing was manually interacting with each of these systems, including
with addons that register their own types.

wm_gizmomap_handler_context_op currently prints an error message to the
console when screen layouts change while modal operations are running.
The operations work, and the comment above it says "this is not an
error to print", and it is confusing for users to see a console message
like this. Looks to be a left-over debugging tool.

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.
For more details see the developer docs:

Replace 'over-allocation' by a standard `blender::Vector` storage for
the `wmGizmoProperty` target properties of the gizmo. This simplifies code somewhat, and
makes the code ready to manage non-trivial types of data.
Explicit default values are also given to all data of `wmGizmoProperty`,
as it appears that the default constructor will not nullify values in
the (trivial) embedded `custom_func` struct.
NOTE: There is much more that could be done in the wmGizmo area to make
it use modern C++ features. The scope of this refactor is strictly
limited to allowing C++ construction/destruction of the wmGizmoProperty
data, as it embeds a PointerRNA pointer that will soon become
a non-trivial C++ struct.

Match function and declaration names, picking names based on
consistency with related code & clarity.
Also changes for old conventions, missed in previous cleanups:
- name -> filepath
- tname -> newname
- maxlen -> maxncpy
This commit moves generated `RNA_blender.h`, `RNA_prototype.h` and
`RNA_blender_cpp.h` headers to become C++ header files.
It also removes the now useless `RNA_EXTERN_C` defines, and just
directly use the `extern` keyword. We do not need anymore `extern "C"`
declarations here.

This adds support for attaching gizmos for input values. The goal is to make it
easier for users to set input values intuitively in the 3D viewport.
We went through multiple different possible designs until we settled on the one
implemented here. We picked it for it's flexibility and ease of use when using
geometry node assets. The core principle in the design is that **gizmos are
attached to existing input values instead of being the input value themselves**.
This actually fits the existing concept of gizmos in Blender well, but may be a
bit unintutitive in a node setup at first. The attachment is done using links in
the node editor.
The most basic usage of the node is to link a Value node to the new Linear Gizmo
node. This attaches the gizmo to the input value and allows you to change it
from the 3D view. The attachment is indicated by the gizmo icon in the sockets
which are controlled by a gizmo as well as the back-link (notice the double
link) when the gizmo is active.
The core principle makes it straight forward to control the same node setup from
the 3D view with gizmos, or by manually changing input values, or by driving the
input values procedurally.
If the input value is controlled indirectly by other inputs, it's often possible
to **automatically propagate** the gizmo to the actual input.
Backpropagation does not work for all nodes, although more nodes can be
supported over time.
This patch adds the first three gizmo nodes which cover common use cases:
* **Linear Gizmo**: Creates a gizmo that controls a float or integer value using
a linear movement of e.g. an arrow in the 3D viewport.
* **Dial Gizmo**: Creates a circular gizmo in the 3D viewport that can be
rotated to change the attached angle input.
* **Transform Gizmo**: Creates a simple gizmo for location, rotation and scale.
In the future, more built-in gizmos and potentially the ability for custom
gizmos could be added.
All gizmo nodes have a **Transform** geometry output. Using it is optional but
it is recommended when the gizmo is used to control inputs that affect a
geometry. When it is used, Blender will automatically transform the gizmos
together with the geometry that they control. To achieve this, the output should
be merged with the generated geometry using the *Join Geometry* node. The data
contained in *Transform* output is not visible geometry, but just internal
information that helps Blender to give a better user experience when using
gizmos.
The gizmo nodes have a multi-input socket. This allows **controlling multiple
values** with the same gizmo.
Only a small set of **gizmo shapes** is supported initially. It might be
extended in the future but one goal is to give the gizmos used by different node
group assets a familiar look and feel. A similar constraint exists for
**colors**. Currently, one can choose from a fixed set of colors which can be
modified in the theme settings.
The set of **visible gizmos** is determined by a multiple factors because it's
not really feasible to show all possible gizmos at all times. To see any of the
geometry nodes gizmos, the "Active Modifier" option has to be enabled in the
"Viewport Gizmos" popover. Then all gizmos are drawn for which at least one of
the following is true:
* The gizmo controls an input of the active modifier of the active object.
* The gizmo controls a value in a selected node in an open node editor.
* The gizmo controls a pinned value in an open node editor. Pinning works by
clicking the gizmo icon next to the value.

There are still a few places that are more complicated where the replacement
to `IDP_New` isn't obvious, but this commit replaces most uses of the ugly
`IDPropertyTemplate` usage.
"Own" (the adjective) cannot be used on its own. It should be combined
with something like "its own", "our own", "her own", or "the object's own".
It also isn't used separately to mean something like "separate".
Also, "its own" is correct instead of "it's own" which is a misues of the verb.
