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.
Use XCURSOR_THEME & XCURSOR_SIZE environment variables for Wayland.
While this isn't an official part of the spec, many Wayland compositors
& applications use these variables.
Currently a developer that starts blender with `--debug-gpu` or
runs the GPU test cases can receive an error when not the full
VulkanSDK is installed.
The VulkanSDK isn't required for normal developement and
therefore it is better to show it as a warning.
NOTE: VulkanSDK is adviced to use when developing in the Vulkan
backend as it contains tools that helps/speed up the development
and validation during development.

On the Windows platform, raise windows and give them focus as the mouse
hovers over them. This allows keyboard shortcuts for the area under the
mouse without having to click the window caption to make them active.
Pull Request #104681
Revert of commits that allowed non-temp Blender windows to be saved
and restored that spanned multiple monitors on the Windows platform.
This causes problems with temp windows (like Preferences & Render) that
cannot currently be fixed.
See 104956 for much more details.
This change is being redone after it was accidentally reverted.

This patch adds initial support for compute shaders to
the vulkan backend. As the development is oriented to the test-
cases we have the implementation is limited to what is used there.
It has been validated that with this patch that the following test
cases are running as expected
- `GPUVulkanTest.gpu_shader_compute_vbo`
- `GPUVulkanTest.gpu_shader_compute_ibo`
- `GPUVulkanTest.gpu_shader_compute_ssbo`
- `GPUVulkanTest.gpu_storage_buffer_create_update_read`
- `GPUVulkanTest.gpu_shader_compute_2d`
This patch includes:
- Allocating VkBuffer on device.
- Uploading data from CPU to VkBuffer.
- Binding VkBuffer as SSBO to a compute shader.
- Execute compute shader and altering VkBuffer.
- Download the VkBuffer to CPU ram.
- Validate that it worked.
- Use device only vertex buffer as SSBO
- Use device only index buffer as SSBO
- Use device only image buffers
GHOST API has been changed as the original design was created before
we even had support for compute shaders in blender. The function
`GHOST_getVulkanBackbuffer` has been separated to retrieve the command
buffer without a backbuffer (`GHOST_getVulkanCommandBuffer`). In order
to do correct command buffer processing we needed access to the queue
owned by GHOST. This is returned as part of the `GHOST_getVulkanHandles`
function.
Open topics (not considered part of this patch)
- Memory barriers & command buffer encoding
- Indirect compute dispatching
- Rest of the test cases
- Data conversions when requested data format is different than on device.
- GPUVulkanTest.gpu_shader_compute_1d is supported on AMD devices.
NVIDIA doesn't seem to support 1d textures.

This reverts commit 19222627c6.
Something went wrong here, seems like this commit merged the main branch
into the release branch, which should never be done.
This reverts commit 68181c2560.
I merged 3.6 into 3.5 by mistake. Basically I had a PR against main,
then changed it in the last minute to be against 3.5 via the
web-interface unaware that I shouldn't do it without updating the
patch.

Note that the node group has its sockets names
translated, while the built-in nodes don't.
So we need to use data_ for the built-in nodes names,
and the sockets of the created node groups.

This better aligns with OSX/Linux warnings.
Although `__pragma(warning(suppress:4100))` is not the same as
`__attribute__((__unused__))` in gcc (which only affects the attribute
instead of the line), it still seems to be better to use it than to
hide the warning entirely.
Mutex locks for manipulating GHOST_System::m_timerManager from
GHOST_SystemWayland relied on WAYLAND being the only user of the
timer-manager.
This isn't the case as timers are fired from
`GHOST_System::dispatchEvents`.
Resolve by using a separate timer-manager for wayland key-repeat timers.
Resolve a thread safety issue reported by valgrind's helgrind checker,
although I wasn't able to redo the error in practice.
NULL check on the key-repeat timer also needs to lock, otherwise it's
possible the timer is set in another thread before the lock is acquired.
Now all key-repeat timer access which may run from a thread
locks the timer mutex before any checks or timer manipulation.
