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 increased amount of BSDF code from Principled BSDF v2 and the
microfacet BSDF led to a big performance regression on Metal and AMD.
We have not been able to find a good workaround for all scenes.
This change disables the Principled Hair BSDF code when it is not used
in the scene. This makes common benchmark scenes faster, but
performance is still bad in scenes that do use it.

This was a regression after the sphere light changes, where the normal
now is the normal along the geometry of the light and no longer suitable
for the IES texture direction.
This not only fixes point lights with non-zero radius, but makes the IES
texture direction work consistently across light types and meshes,
always rotated by the object transform.
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.
Update the OSL script for the "Geometry" node to follow the correct
Tangent code path when working with point clouds.
There should be no functional change for the end user since the correct
code path was already taken by accident.

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.

Cycles implements the "Taming the Shadow Terminator" paper by Matt Jen-Yuan
Chiang to solve shadow terminator issues when a bump map is applied, as well
as similar approach for the glossy reflection to ensure ray does not get
reflected to inside of the object.
This correction term is applied unconditionally, which makes it harder to have
full control over shading via normals for stylistic reasons.
This change exposes this corrective term as an option called "Bump Map
Correction" which is available in the shader settings next to the
"Transparent Shadows".
The reason to make it per-shader rather than per-object is to allow flexibility
of a control: it is possible that an object has multiple shaders attached to it,
and only some of them used for bump mapping. Another, and possibly stronger
reason to have it per-shader is ease of assets control: shader brings settings
which are needed for its proper behavior. So if material at some point
decides to take over normals, artists would not need to update settings on
every asset which uses that material.
The option is enabled by default, so there is no changes for existing setups.
