- CTX_wm_region(C) must be NULL checked as it's not checked in the
poll function.
- Add back the removed flag, note it's dirty.
- Replace ternary operators with min/max.
Prefer the name 'hit_result' since 'result' was sometimes used for
a vector of GPUSelectResult and is often used a functions return value.
Use hit_results for the span/vector and hit_result for a single hit.
Also assign struct members for new GPUSelectResult as it reads better
and avoids depending on struct order.
- Pass Span by value. It is a small struct, and passed by reference
it acts as a pointer to a pointer.
- Remove unnecessary `= {}`. Vector has a default constructor.
- Use initializer list Span constructor to avoid temporary array.

These are just duplicates of the pointers in `SubdivCCG`, which are
already quickly accessible. Keeping track of the state is too complex
and bloats the responsibilities of the PBVH too much.
This commit aim at making the behaviors of `BLI_rename` and
`BLI_rename_overwrite` more consistent and coherent across all
supported platforms.
* `BLI_rename` now only succeeds in case the target `to` path does not
exists (similar to Windows `rename` behavior).
* `BLI_rename_overwrite` allows to replace an existing target `to` file
or (empty) directory (similar to Unix `rename` behavior).
NOTE: In case the target is open by some process on the system, trying
to overwrite it will still fail on Windows, while it should succeed on
Unix-like systems.
The main change for Windows is the usage of `MoveFileExW`
instead of `_wrename`, which allows for 'native support' of file
overwrite (using the `MOVEFILE_REPLACE_EXISTING` flag). Directories
still need to be explicitly removed though.
The main change for *nix systems is the use of `renamex_np` (OSX) or
`renameat2` (most Linux systems) to allow forbidding renaming to an
already existing target in an 'atomic' way.
NOTE: While this commit aims at avoiding the TOC/TOU problem as
much as possible by using available system's primitives for most
common cases, there are some situations where race conditions
(filesystem changes between checks on FS state, and actual rename
operation) remain possible.

Parallelize the implementation and move constant checks out of hot
loops. Only push undo steps for PBVH nodes that actually have changed
hide status. Optimize the "show all" case to remove the hide attributes.
For timings, I recorded some information on a 16 million vertex mesh:
- Hide masked (1/4 of mesh): 171 ms to 33 ms
- Hide small box: 13 ms to 14 ms
- Show all with small box hidden: 226 ms to 10 ms
- Show with all visible: 173 ms to 0.36 ms
There are a few other visbility operators that aren't affected:
- SCULPT_OT_face_set_invert_visibility
- SCULPT_OT_reveal_all
- SCULPT_OT_face_set_change_visibility
In separate steps, they should be moved to use the same structure, or
maybe even removed in the case of "reveal all".
I expect the "gather, change hidden verts, scatter" steps for each node
could be made a bit more efficient, they do some redundant work.
But it was also a simple way to share a reasonable amount of code.
Use multithreading, plus make the non-float / non-separate luma
calculations faster by avoiding byte->float->byte conversions
back and forth.
On a 4K resolution sequencer display, time taken to calculate the
waveform (Windows, Ryzen 5950X):
- regular images: 127.0ms -> 6.4ms
- regular images, separate colors: 160.3ms -> 13.1ms
- float images: 86.2ms -> 11.1ms
- float images, separate colors: 162.9ms -> 17.4ms
This also fixes curious "one black pixel row" in the middle of the
waveform, which was caused by the code spreading 256 possible luma
values over "off by one" vertical range:

Exposed by 383a145a19.
Think the issue actually started in cfa53e0fbe, since then the new
destination normals were only filled from the first array copy onwards
(probably hidden by some recalculation of normals somewhere?).
In any case, starting the destination normals array with what we have
from the input mesh normals and then resizing the array (instead of
reinitializing it from scratch) fixes this.

The grease pencil draw tool would still do a lot of smoothing
even if the active smoothing factor was set to 0.0.
This was because the screen space coordinates were always pre-blurred
before being passed to the curve fitting. Even if the curve fitting
outputs a line that fits the input exactly, it would still use the pre
smoothed coordinates.
The fix makes sure to use the smoothing factor in the influence
of the pre-blur. This way, no pre-blur is used when the factor is 0
and the lines will be smoothed much less.
Note that we always do some smoothing to avoid artifacts such
as pixel-grid-aligned lines etc.
When keyframing with the `Only Insert Needed` flag enabled,
the code was able to delete keyframes in certain cases.
This behavior is removed and replaced with the following rules.
* If there is a key on the current frame, and it has the same value, skip it.
* If there is no key, but the FCurve evaluates to the same value, skip it.
* Add a key in all other cases.
Remove that functionality for consistency and simplify the code around it.

This patch adds a number of utilities to handle texture formats and
their relation to result types and precisions. This is needed for future
work, and also unifies the places one needs to update when adding a new
result type.
You could already do overshoot via the mouse, but it was arbitrarily
disallowed when entering values numerically. This simply lifts that
restriction so that numerical input is capable of the same things as
dragging the mouse.
Importantly, the operator slider code already appropriately clamps
both mouse and numerical input when needed. So the checks and clamping
removed in this commit simply aren't needed, and removing them just
makes numerical input get constrained exactly the same as mouse input.

This patch implements a new mechanism for compositor results to wrap
external images, such as those cached in the static cache manager.
Thereby enabling zero cost use of those resources, which previously
needed a copy at each evaluation.

Selection logic in ed_object_select_pick mixed operations for
object mode & other modes, making it difficult to reason about.
Refactor so object mode selection is isolated to it's own block,
following conventions for SelectPick_Params used by all other selection
picking operators.
This makes it possible to remove a call to de-select all objects
which was redundant in most cases.
Pass-through selection allows select-drag not to activate an already
selected object - so an existing selection can be dragged without
changing the active/selection (see #96544) & [0],
This caused entering pose-mode to fail when selecting an armature
with "Lock Object Modes" disabled.
There is a logical conflict where pass-through is intended to keep the
current selection & active, which doesn't make sense when selecting the
armature should enter pose-mode (details in code-comments).
Resolve by disabling pass-through when the select action changes
the objects mode.

Sequencer timeline UI repainting is 3x-4x faster now, for complex
timelines. On Sprite Fright Edit data set, with whole timeline visible
(2702 strips), repainting the timeline UI with all overlay options
(waveforms, offsets, thumbnails etc.):
- Windows (Ryzen 5950X, RTX 3080Ti, OpenGL): 62ms -> 18.6ms (16FPS -> 54FPS)
- Mac (M1 Max, Metal): 39.8ms -> 11.5ms (25FPS -> 86FPS)
This is achieved by:
- Avoiding tiny GPU draw calls (i.e. drawing one quad a time), instead
batch all the quads / lines needed by the timeline display into
series of about-1000 quads per draw.
- For retiming keys display, batch their keyframe point drawing too.
- For audio waveform overlay display, change it to draw batched quads
instead of alternating between line strips and triangle strips. This
actually changes how the waveform looks like (implements #115274)
and fixes some visual issues with waveforms too.
- For fcurve overlays, also draw them as batched quads.
While at it, this also fixes an issue where while dragging strips over
other strips, their text labels would look as if they are behind the
background strips.

Our `EnumerableThreadSpecific` wrapper doesn't accept an
example argument, only an initialization function. And some
removed variables were still used in asserts.

Since above commit, normals were in a SharedCache, they need to be tagged dirty
for recalculation.
Instead of tagging the normals caches dirty explicitly, simply use
`BKE_mesh_tag_positions_changed` [which includes all this and also tags
positions dirty - which sounds also needed for updating other things]
