2a757f469c Fix cursor size being ignored by custom cursors under Wayland
The theme cursor size was ignored when setting custom cursors
such as the knife, only the DPI from GHOST was taken into account.

This meant cursors such as the knife would sometimes display too small.

Now when the theme-size is larger, a larger cursor will be used.

Currently the theme size is read from XCURSOR_SIZE environment variable
however it may be read from the system preferences in the future.

Also fix the software cursor sizes which incorrectly used the UI scale
preference which is ignored by cursor sizes.

e63a20fee1 Vulkan: HDR support for Wayland
This change enables HDR support for wayland as an experimental feature.
It supports both non-linear extended sRGB and un-clamped sRGB.

Windows isn't supported as the HDR settings are not accessible via an
API and would require similar settings that games use to configure the
monitor. Adding those sliders isn't what we would like to add.

Vulkan (working group) is working on new extensions that might change
the shortcomings. It isn't clear yet what the extension will do and what
the impact is for applications that want to use it. When the extension
is out we should review at the situation again.

c8aa20f8b3 Cleanup: Remove titlebar text color from decoration style settings
When the colored titlebar decoration style was implemented in
PR #123982, both the titlebar background and foreground were exposed
to the OS backends to be used when styling the Blender window titlebar.

In practice, both backends that implement this decoration style (Win32
and macOS/Cocoa) only use the background color, and they either rely on
the OS to automatically set the text color or use the color HSV value
component to switch between the OS dark/white color.

While it was thought to still keep this value around for a potential
future backend implementation, the color settings parsed to obtain the
titlebar color (`TH_BUTBACK_TEXT_HI`, which wasn't properly suited for
this feature to begin with) has been replaced by `TH_TEXT` in #140726,
which ends up being too bright to be used as titlebar text for most
themes/use cases.

As such, this PR removes this unused titlebar decoration style setting.
Future backends that wishes the implement the colored titlebar
decoration style should either use an existing OS/DE text color or use
a set white/dark text color, similarly to what the Cocoa backend does.

17bda2cf3f Cycles: Enable multi-bounce random walk subsurface scattering
Multi-bounce was mainly disabled for disk sampling where the probability of
hitting something is relatively low even with high albedo, but this is not so
much an issue with random walk.

This reduces darkening artifacts at the cost of some extra render time. The
difference is mainly visible when using a high radius.

49ae867de4 Fix #139870: Cycles: Some objects with normal maps leak light
This was broken by !138632, the refactor of the microfacet code to no longer
check the "geometric normal", which in reality was the smoothed normal.

Since the logic is now the same for all closure types, it seemed weird that
the light leak only affects Microfacet closures, not Diffuse.

Turns out that for diffuse closures, the relevant paths were rejected by
the initial hemisphere check in the smooth bump terminator code, which also
incorporates the smoothed but non-bump/normal-mapped normal sd->N.

So, we can detect and prevent the new light leaks by extending this check to
all closure types for the eval case. Sampling already has stricter checks,
so this doesn't apply there.

With this change, we can revert the two test cases back to their pre-refactor
version. In hindsight it was a mistake to just shrug off these changes as okay,
I should have looked closer into the difference.

The distributed memory access toggle in Cycles preferences would show up

2df163a648 Fix: Cycles low performance with scenes with many shaders on Arc B570
The performance of the sorted_paths_array kernel on B570 is problematic.
Relying on local sorting+partitioning instead gives a 25% overall rendering
speedup and no regression in shade_surface when rendering Agent 327 Barbershop scene.
On Arc A770, it still gives a 2% speedup when rendering Barbershop.

b561c78f93 Nodes: Remove legacy combine/separate nodes
In Blender 3.3 (1) the individual combine and separate color nodes were
combined together into a single combine/separate color node.

To ensure legacy addons still worked, the old nodes were left in
Blender, but hidden from the Add menus.

It has been nearly 3 years since that change was made, most if not all
addons should have been updated by now. So this commit removes these
hidden legacy nodes.

b920f6f1a7 Shaders: Remove point density texture node
This is replaced by geometry nodes, where volumes can now be generated from
point clouds and meshes with more control, and more efficient rendering as a
sparse volume.

No backwareds compatibility is provided, as this would be complicated, and
probably this feature was not used much in the past few years.

This node was supported in Cycles only, not by EEVEE.

68111db969 Nodes: Speedup Voronoi by changing the hash function
The 2D->2D, 3D->3D, 4D->4D hash functions used in Voronoi node were
using quite an expensive hash function. Switch these to dedicated
2D/3D/4D hash functions (pcg2d, pcg3d, pcg4d) -- these are still very
good quality, but the hash function itself is 3x-4x faster.
Which makes Voronoi node calculation overall be around 2x faster. In
some cases when using OSL, the speedup is even larger.

This visibly changes output of the Voronoi noise however. The actual
noise "behaves" the same, just if someone was depending on the noise
pattern being exactly like it was before, this will change the pattern.

Images, more performance results and details wrt OSL are in the PR.

e16b6ac3da EEVEE: Add support for view layer overrides
This was a missing features in EEVEE for ages which
was in fact very easy to implement.

EEVEE implements the sample override like the default
`Use` value in Cycles. It always override the sample
count if not 0. Adding a new option for changing this
behavior just like Cycles can be done later while
at the same time making the option more understandable
and its value moved to the blender's DNA.

This PR moves the UI panel to the Blender side to
be shared between Cycles and EEVEE.

unperturbed normal in this case.

bc80ef136e Big Endian Support Removal.
This commit implements #125759.

It removes:
* Blender does not build on big endian systems anymore.
* Support for opening blendfiles written from a big endian system is
  removed.

It keeps:
* Support to generate thumbnails from big endian blendfiles.
* BE support in `extern` or `intern` libraries, including Cycles.
* Support to open big endian versions of third party file formats:
  - PLY files.
  - Some image files (cineon, ...).

f8eec542f4 Core: always free memory on exit, always report leaks
Instead of allowing leaks when parsing arguments, always cleanup before
calling exit(). This impacts -a (animation player), --help & --version
arguments, as well as scripts executed via --python which meant tests
that ran scripts could leak memory without raising an error as intended.

Avoid having suppress warnings & rationalize in code-comments when
leaking memory is/isn't acceptable, any leaks from the animation-player
are now reported as well.

This change exposed leaks: !140182, !140116.

This prevents the use of unaligned data types in
vertex formats. These formats are not supported on many
platform.

This simplify the `GPUVertexFormat` class a lot as
we do not need packing shenanigans anymore and just
compute the vertex stride.

The old enums are kept for progressive porting of the
backends and user code.

This will break compatibility with python addons.

f23f498864 Fix #139815: Vulkan: Infinite loop when loading minimized windows
e934792169 introduced a workaround for
NVIDIA windows where NVIDIA drivers fail to allocate swapchain images
of minimized windows. The fix was to clamp it to 1,1. With this clamping
AMD driver seems to tell Blender that the created swapchain is suboptimal,
and needs to be recreated. This results in over and over creation of
swapchains as they are all considered sub-optimal.

This PR limits the clamping to NVIDIA drivers only.
