Tested with IBUS on GNOME 45.
Added a capabilities flag to GHOST since support for IME works on
Wayland but not on X11, so runtime detection is needed.
Resolve issues with corner-cases introduced by [0].
- Comparing the filename & filepath was no longer a valid way to check
for a directory component since the extension was stripped.
- Use BLI_path_extension_or_end which doesn't confuse extensions with
the dot from hidden files.
The variable name include_directory was also misleading.

In some cases processing events was modifying them, as there can be
multiple event consumers, manipulating events isn't correct.
Even though in practice it didn't cause issues, it's straightforward
not to do this and makes logic easier to reason about.
IME editing would cast GHOST_TEventImeData to wmIMEData then read/write
an additional member that doesn't exist in GHOST_TEventImeData.
In practice it's likely struct padding prevented this from showing up
as a bug. Nevertheless it's bad practice to rely on this.
- Make GHOST_TEventImeData read-only, move the is_ime_composing boolean
into the window.
- Add static assert to ensure both structs are the same size.
- Correct code comments.
Resizing a window in Wayland caused cursor motion events in the window
which could be seen as buttons flashing when the cursor was detected
as hovering over buttons.
This was caused by two bugs:
- Missing checks for failure to access the cursor location before
converting the coordinates from GHOST to screen-space meant the
wmWindow::eventstate location would move each time the location
was updated.
- Resizing the window wasn't detecting state changes and would
continuously send window activation events. Window activation set
wmWindpw::addmousemove which triggered the previous bug, making the
cursor flicker during resize.
This commit only addresses the first issue, where failure to access
the cursor location wasn't accounted for
(window activation will be fixed separately).
All GHOST_GetCursorPosition & wm_cursor_position_get calls now account
for failure, resolving uninitialized stack memory use in some cases.
This resolves similar issues for macOS, WIN32 & X11 although it seems
likely these platforms rarely fail to access the cursor location.
The problem was introduced in 636f3697ee
MacOS has a different way of handling the title.
In this OS the directory is searched and taken from the title string
which is then formatted.
This limits the title format and makes it prone to errors.
This commit makes the code more generic by splitting each component of
the title beforehand and allowing the associated directory to be informed
with `GHOST_SetTitle`.
Disambiguate:
- Rename "Near" to "Proximity" as a particle event type, because using
an adjective in this context is inconsistent and sounds
strange (even in English IMO).
Extract:
- "Skip" (Geometry nodes Simulation node output socket)
- "Bake" (Directory path to geometry nodes bake files in the modifier
UI)
- " (Recovered)" (File information in title bar)

It's possible for there to be no outputs under Wayland
(when unplugging monitors for e.g.) so this must be accounted for.
Also avoid calculating the window position when the GHOST backend
doesn't support window positions (which is the case for Wayland).
Add checks for the SDL backend too, where accessing the
screen & desktop size may fail.
When a timer needs to execute during the idle time (currently 5ms), use
microsecond precision to ensure the timer isn't delayed by the idle
time.
This improves the precision of animation playback on systems that
support it
(WIN32, see note below).
In my tests FPS playback varied:
- 59.94 FPS would jitter between 58.13 & 63.11 FPS. 23.98 FPS would
- jitter between 23.68 & 24.31 FPS.
Using higher precision timers mostly resolves this issue although there
is still some jitter although it's now limited to ~0.01 FPS.
These values were measured with the FPS-Samples set to 1 to show the
real times between frames (without the values being smoothed out).
This is a continuation of a fix for #111579 which avoided the worst of
the jittering issues at higher frame rates.
It appears WIN32 doesn't support sleeping shorter than 1 millisecond via
`std::this_thread::sleep_for`, making this change have no benefit on
WIN32, from tests it also doesn't have any down sides, so avoid platform
specific logic. The WIN32 limitation is noted in code-comments. If a
method of higher precision method is available this can be investigated.
Setting the FPS to 120 caused the FPS to flicker erratically between
130 & 140 FPS.
This also impacted lower frame-rates with 23.98 playing back at 24.03
FPS on my system, 30 FPS played back at 30.13 FPS.
This problem was hidden by the FPS display rounding to an integer.
Regression in 2.5x series (worked in 2.49).
Resolve by clamping the sleep time in the main event loop so the 5ms
sleep doesn't result in sleeping when timers are scheduled to run.
There is still some visible FPS jitter that can be solved by using a
higher resolution sleep interval but that's out of scope for this fix.
This adds a new Ghost function, GHOST_GetPixelAtCursor, that allows
picking colors from outside of Blender windows. This only has an
implementation for the Windows platform, but this should allow other
platforms to also do so if possible.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
Using ClangBuildAnalyzer on the whole Blender build, it was pointing
out that BLI_math.h is the heaviest "header hub" (i.e. non tiny file
that is included a lot).
However, there's very little (actually zero) source files in Blender
that need "all the math" (base, colors, vectors, matrices,
quaternions, intersection, interpolation, statistics, solvers and
time). A common use case is source files needing just vectors, or
just vectors & matrices, or just colors etc. Actually, 181 files
were including the whole math thing without needing it at all.
This change removes BLI_math.h completely, and instead in all the
places that need it, includes BLI_math_vector.h or BLI_math_color.h
and so on.
Change from that:
- BLI_math_color.h was included 1399 times -> now 408 (took 114.0sec
to parse -> now 36.3sec)
- BLI_simd.h 1403 -> 418 (109.7sec -> 34.9sec).
Full rebuild of Blender (Apple M1, Xcode, RelWithDebInfo) is not
affected much (342sec -> 334sec). Most of benefit would be when
someone's changing BLI_simd.h or BLI_math_color.h or similar files,
that now there's 3x fewer files result in a recompile.
