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.
The USE_LIBDECOR_FRACTIONAL_SCALE_HACK worked on my system but made
window size issues worse in older versions of GNOME, see: #109194.
Replace the hack with logic to set the window size using frational
scaling information from the output.
When fractional scaling is used, window sizes from LIBDECOR are still
divided by the window-decorations internal buffer scale which doesn't
match the GHOST window (always 1 in the case of fractional scale).
Also resolve glitches caused by recalculating the window size when
no size change was intended. In this case reuse LIBDECOR's internal
size so there are never any changes (caused by rounding for e.g.).
When the window manager set the window size, there were no checks
the size is a multiple of the buffer scale (a requirement for Wayland).
This meant setting the window size could exit Blender without warning
if an invalid window size was set.
When fractional scaling was used with libdecor the window decorations
would not match the window size on startup, drawing small and on top
of Blender's window.
While there are still glitches with fractional-scaling & libdecor
(which doesn't support fractional scaling),
see #109194 this at least resolves one of the worst issues.
When a new window is created the final buffer scale isn't known
so setting the buffer scale assuming the final state was just a guess
and only had the minor advantage of preventing rounding the window size
on startup.
Removing this to resolve a bug with LIBDECOR & fractional scaling
relating to #109194 (will commit separately).
When running Blender inside renderdoc an extension can be used to print
from any shader stage to the console. This is useful during developing,
but not so during running/triaging. For now we remove the extension to
not confuse by incorrect error messages.

This PR adds workarounds for platforms that don't support `shaderOutputLayer`
or `shaderOutputViewportIndex`. Some NVIDIA laptop GPUs and ARM GPUs don't
have those device features.
The workaround uses the same approach as OpenGL. A geometry shader is injected
to emulate the feature.
For testing the workarounds they have also been connected to the
`--debug-gpu-force-workarounds` command line argument.

Windows mouse warping bounds margin needs to be different when not
GHOST_kGrabHide, or else the visible wrapping occurs within the
area at an odd location. Making it 2, like it used to be.
The issue was caused by the custom code which was ensuring that closing
About window does not leave application without any key
windows.
Turns out that the windowWillClose is executed when menu is closed,
forcing the custom code to ensure a key window.
The solution is to only perform manual re-ordering if the closing window
was a key window. This both keeps old behavior of ensuring there is a
key window after closing About, and solves the ordering issues when a
window is created or activated via menus.

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.
This was only used for accessing cursor themes which only worked
with gnome and wasn't used in official releases.
Use the default theme or the theme defined by XCURSOR_THEME.
Eventually wp_cursor_shape_manager_v1 can be supported which avoids
having to access the theme.
Wayland WSI would crash the system when used. The reason is that the
wayland vulkan WSI doesn't provide windowing support. Vulkan gets full access
to the desktop of the OS and it is the responsibilty of the application to
do the right thing.
For OpenGL Wayland proved basic windowing support using `wayland-egl.h`.
Which essentially is a tiny wrapper that keeps track of the window position and
size.
This PR changes a few things to make the Wayland surface usable:
- Do not load debug extensions when blender isn't started with
`--debug-gpu`.
- Recreate swapchain images when surface size changes.
