During createOffscreenContext with VK backend enabled wl_surface
was not stored in the context's user data. This resulted in nullptr
dereference later on during disposeContext. Added a line that sets
user data and additionally added nullptr checks in disposeContext.

Expand on why front-buffer support is always disabled on Wayland &
why viewport orbit around selection offset correction isn't used for
perspective views.
- Use off-screen drawing when reading from the front-buffer isn't
supported.
- Add a capabilities flag for reading the front-buffer which is always
disabled on WAYLAND.
- Add GPU_offscreen_read_pixels_region, used for reading a sub-region of
an off-screen buffer - use for color-picking a single pixel.
After double clicking a file, user can click on a different app and
Blender will lose focus. Then it stays on splash screen. So fetch any
window instead of relying on active one to open the file.

This reverts commit 4fe2685615.
Always use the preferred_scale requested by the compositor as this
did not work so well in the intended use case (where the low resolution
monitor text was scaled down and difficult to see).
After discussion with @ZedDB, revert this change since there are cases
where either functionality might be preferred - to ensure Blender's UI
is visible on a low resolution mirrored projector for e.g.
Changing the behavior of the preferred scale makes most sense in the
compositor, instead of controlling it on a per-application basis.
Defer acting on the tag to update scale as it caused the window
to use the wrong scale on startup & exit.
GTK/KDE applications seem to postpone updating scale so use this by
default as glitches with scale tend to be caused by updating the scale
too frequently instead of not quickly enough.
There is no need to postpone these operations when configuring the frame
only postpone committing the surface change.
Deferring these operations caused flickering when moving windows
between monitors of different scale on both GNOME & KDE.
Freeing ContextEGL would attempt to free the context's EGLSurface,
which was already freed by the native-window, causing 2x bad-surface
errors on exit.
Suppress the warning by clearing the surface from releaseNativeHandles
when the surface was created by a native window.
Updating the buffer scale increased the window size based on the
previous window scale. Since the previous scale (DPI) newly created
windows restored from a `.blend` file isn't known, don't scale the
window size when updating the window's scale for the first time.
When a window overlaps multiple outputs, always use the resolution
on the output with the highest resolution. This means Blender never
shows low resolution content up-scaled.
Share logic between fractional & non-fractional window scaling.
This also enables fractional-scaling without scaling fixed sized buffers
for compositors without support for fractional_scale_manager_v1.
Logic for the recently included fractional scaling support [0] was
difficult to reason about as it depended on two different callbacks
one that listened to a preferred scale, another that tracked which
physical displays the window overlapped.
Checking if fractional scaling was in used depended on the order
the callbacks ran - which is undefined.
In practice - mixing non-fractional and fractional displays would
flicker when the window was moved between monitors.
Resolve this problem with the following changes:
- When the fractional-scale manager is supported,
only respond to the scale from it's preferred_scale callback.
- When no fractional-scale manager is available,
set the scale based on the scale of overlapping outputs.
- Add support for postponing the buffers commit call to prevent
flickering when changing the windows scale.
Other changes:
- Use a lock before setting the pending frame state from
wp_fractional_scale_handle_preferred_scale.
- Ensure pending actions that themselves trigger pending actions
run in the time gwl_window_pending_actions_handle is called.
- Rename GWL_Window::scale -> GWL_WindowFrame::buffer_scale.

Depend on fractional-scale when searching for wayland-protocols
This will impact builders that don't use Blender's `../lib/` and
have wayland-protocols older than v1.31.
Previously, fractional scaling was detected but set an integer buffer
scale which the compositor would down-scale causing blurry output.
Now the fractional scaling interface is used when available to set the
DPI and set the internal buffers size & viewport transformation to
ensure 1:1 pixels from Blender to the Wayland output.
Tested to work with multiple monitors with mixed
fractional/non-fractional scale.
Note that this change causes a regression for when fractional scaling
is set on a compositor without support for fractional-scale-v1.
Supporting fractional scaling in both cases is possible but overly
complicated. This case already wasn't working so well - with blurry
output due to image scaling, now the DPI wont be accurate in this case
although Blender is still usable.
The goal is to solve confusion of the "All rights reserved" for licensing
code under an open-source license.
The phrase "All rights reserved" comes from a historical convention that
required this phrase for the copyright protection to apply. This convention
is no longer relevant.
However, even though the phrase has no meaning in establishing the copyright
it has not lost meaning in terms of licensing.
This change makes it so code under the Blender Foundation copyright does
not use "all rights reserved". This is also how the GPL license itself
states how to apply it to the source code:
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software ...
This change does not change copyright notice in cases when the copyright
is dual (BF and an author), or just an author of the code. It also does
mot change copyright which is inherited from NaN Holding BV as it needs
some further investigation about what is the proper way to handle it.
For example
```
OIIOOutputDriver::~OIIOOutputDriver()
{
}
```
becomes
```
OIIOOutputDriver::~OIIOOutputDriver() {}
```
Saves quite some vertical space, which is especially handy for
constructors.

The DPI returned by the GHOST/Wayland didn't account the buffer being
rendered at a higher (non-fractional) resolution, then scaled down.
This caused the software cursor and UI to rendered very small.
A fractional scale of 101% would show the UI just over 50% of the size
(making the UI to be close to half the scale it should have been).
Resolve by accounting for down-scaling of the buffer to it's
fractional size.
This PR adds pre-checks when enabling validation layers.
For validation layers to work some platforms require that
the Vulkan SDK is installed. Validation layers are activated
when running blender with `--debug-gpu`.
Sometimes we expect users to run with `--debug-gpu` for
narrowing down an issue and we cannot expect them to have
the Vulkan SDK installed.
This patch will check if the `VK_LAYER_PATH` is available
and that the configuration file of the validation layer is
present. If this isn't the case we don't activate the
requested validation layer.

Calling render (for example) with an existing window open now activates
the window on Wayland. Tested to work on GNOME & KDE.
Use the xdg-activation protocol which typically brings the
window to the foreground.
Partially resolves#102985.
Clang would warn about failure to use 'override' when a single
method was added that used 'override' when none of the other methods
did.
This meant a single correct use of override caused noisy compiler
warnings (for CLANG but not GCC).
Avoid this by using 'override' where appropriate.
Adding checks for platform capabilities involved adding functions
to multiple classes and was too involved.
Replace this with a single GHOST_System::getCapabilities() function.
Workaround gnome-shell including uninitialized memory when pasting
from the clipboard. Where `read` would not write data into the range
return by the length.
Reading from the pipe into a power-of-two buffer
works around the problem.
It's not clear why this only impacts gnome-shell - as there is no
significant down-side to changing the buffer size, apply a workaround.

Only the text editor supported the primary clipboard & only for modal
selection. Now selecting text in the console & 3D text editing also
sets the primary clipboard under X11 & Wayland.
Notes:
- Pasting from the primary clipboard isn't yet exposed in the key-map
so in practice it's only useful for pasting text outside of Blender.
- Use skip-save option when pasting from the primary selection
so this is never used by the regular paste shortcut.
- This commit adds a primary-clipboard flag to WM_capabilities_flag() so
creating the the copy-buffer is only performed when necessary.
