The external cancel callback destroyed the data source but didn't
clear the pointer. While this didn't cause problems,
avoid keeping references freed pointers.
Add command line argument to switch gpu backend. Add `--gpu-backend` option to
override the gpu backend selected by Blender.
Values for this option that will be available in releases for now are:
* opengl: Force blender to select OpenGL backend.
During development and depending on compile options additional values can exist:
* metal: Force Blender to select Metal backend.
When this option isn't provided the internal logic for GPU backend selection will be used.
Note that this is at the time of writing the same as always selecting the opengl backend.

Smooth & discrete scrolling may both be set, instead of always
prioritizing discrete, use discrete scrolling when the source is a
mouse wheel, otherwise prioritize smooth scrolling.
These events are interpreted as MOUSEPAN by Blender.
Tested with a Wacom Intuos5. This isn't full touch support
which is needed to support gestures such as Swipe, Rotate .. etc.
Previously this was only available as a build options, making it
difficult to get user feedback when NDOF events didn't work as expected.
Now logging can be enabled with:
blender --log "ghost.ndof.*" --log-level 2 --log-show-basename
- Use `_` suffix for private members.
- Use `wl_` prefix for Wayland native types to help distinguish
them from local types.
- Replace single character names `d` & `w` with `display` `window`.
- Rename `selection` to `clipboard`. Using the primary selection as a
clipboard is a separate and as yet unsupported feature.
- Support switching between libdecor and xdg_shell at run-time.
- Require libdecor when using gnome-shell, otherwise use xdg_shell.
- Gnome-shell detection checks for a gtk_shell* interface which
isn't ideal however it's not possible to check server-side-decorations
are supported without first creating a window.
- Unload Wayland libraries when Wayland fails to load.
For some compiler and linker configurations, linking would fail as the
wayland libs were linked at a high level and not at the actual code
where they were needed.
After talking to Campbell, we decided to clean up this part and now
only link both the X11 and Wayland libs where they are used.
Previously only failure to dynamically load libdecor would report a
warning. Now report failure to load all Wayland libraries.
This was done because Wayland libraries (besides libdecor) are likely to
be installed on systems running Wayland. However it makes it difficult
to troubleshoot failure to load Wayland on systems with libdecor.
Only silence Wayland dynamic loading warnings when Wayland isn't running.
X11 is used as a fallback when libdecor isn't found on the users system.
Now print a warning when Blender falls back to X11 and a missing
libdecor is the only reason wayland could not be used.
Only print this warning when using Wayland so this warning doesn't show
on X11 systems which have Wayland libraries installed.
Addresses T101715.
Show the windowing environment on non MS-Windows/Apple systems,
since X11/WAYLAND are selected startup there was no convenient way
for users to know which back-end was being used.
Include the windowing environment in the About splash & system-info.txt
since it will be useful for handling bug reports.
This commit adds a private API call not intended for general use
as I would like to be able to remove this later and it's only needed
in the specific case of testing if Blender is using WAYLAND or X11
(which maybe be used via XWayland).
Python scripts can already inspect the system to check which windowing
environment used, the API call is mainly useful for troubleshooting.
GNOME (mutter) intentionally doesn't follow the Wayland spec for the
keyboard_enter events (held keys are always an empty array).
This means we can't know which keys are held on window activation,
making the result of getModifierKeys invalid (in that we don't know
which modifiers are held).
Detect this situation and suppress warnings as the issue has been
reported and it doesn't help for users to see noisy warnings for
a known problem.
Rename BKE_appdir_folder_id_version to
BKE_appdir_resource_path_id_with_version because BKE_appdir_folder_id
and BKE_appdir_folder_id_version didn't accept compatible arguments.
Also add notes to GHOST_getSystemDir & GHOST_getUserDir that
BKE_appdir_resource_path_id(..) should be used instead (in most cases).
When the GHOST back-end Blender was built with isn't supported,
Blender would crash on startup without any useful information.
This could happen when building X11 only, then running on Wayland.
Now show a list of the GHOST back-ends that were attempted and exit
with an error code instead of crashing.
Available on Windows and macOS, where such gestures are supported.
For Windows, disabling this option restores touchpad behavior to
match Blender 3.2.

MTLContext provides functionality for command encoding, binding management and graphics device management. MTLImmediate provides simple draw enablement with dynamically encoded data. These draws utilise temporary scratch buffer memory to provide minimal bandwidth overhead during workload submission.
This patch also contains empty placeholders for MTLBatch and MTLDrawList to enable testing of first pixels on-screen without failure.
The Metal API also requires access to the GHOST_Context to ensure the same pre-initialized Metal GPU device is used by the viewport. Given the explicit nature of Metal, explicit control is also needed over presentation, to ensure correct work scheduling and rendering pipeline state.
