Avoid unnecessary indirect includes for the module, which would slow
down compilation. Avoid "using std" which is generally not considered
good practice since it's helpful to see what namespace things are from.
This is just a general cleanup of the area. I was trying to understand
it better to reduce redundant mesh topology storage but finding that
some intermediate cleanups would be helpful to ease the change.

The problem here was that `free_data_after_sync` frees the particle cache in headless or locked-UI mode, but the second view doesn't regenerate them.
For multi-view renders, dropping caches is a tradeoff between compute and memory - dropping allows to reduce peak memory usage, but requires recomputation for the next view. With the current design however, dropping is not something that is easily achievable anyways (see the referenced bugs). So until something more reliable and better fitting is implemented, keep the data from Blender side until the last view.
Since `free_data_after_sync` doesn't do anything for baking or viewport renders anyways, it's easiest to just move this out into `BlenderSession::render` since that already checks whether another view is still outstanding.
Also fixes#73221 and #107589.

get_apple_gpu_architecture will now report if the GPU being checked
is not an Apple GPU.
At the moment this has no functional changes. But it reduces the
chances of mistakes in the future where a developer tries to enable
a feature on newer Apple GPUs using get_apple_gpu_architecture,
and accidentally enables it on unsupported AMD and Intel GPUs.

With the switch to using the primary CUDA context it became possible
for peer access between CUDA devices to already have been enabled for
that context, either by a previous Cycles session or third-party library,
thus causing the call to `cuCtxEnablePeerAccess` to return
`CUDA_ERROR_PEER_ACCESS_ALREADY_ENABLED`. This is not a failure
state however, so just needs to be handled like a success return value.

Extract
- Statuses for the external text editor
- Newly created enum node item
- Newly created plane track data
- Newly created custom orientation data
- Operator names in drag and drop menu (need to use operator's
translation context)
- GN attribute statistic node inputs
Disambiguate
- Single-letter colors: A and B can mean Alpha and Blue, or simply A
and B as in two operands in an operation
- Dissolve: issue reported by Tamar Mebonia in #43295
- Translate in the User Preferences. This introduces a new
BLT_I18NCONTEXT_EDITOR_PREFERENCES ("Preferences") translation
context
- Planar (reported by deathblood)
This one is incomplete, because there is currently no way to
disambiguate presets or GN fields. I don't see how either could be
achieved cleanly.
The former would need to define the context inside the preset and
evaluate the file prior to showing it in the presets menu, which
sound bad.
The latter would need to introduce an additional string inside
`FieldInput`s, which would be controversial given how little it
would be used.
Remove
- Unused translation `iface_("%s")` in toolbar
- Remove obsolete N_() tags in a few node descriptions.

On KDE, running "blender -w" (windowed with borders) created window
which was too big: the window contents matched the screen-size
causing the window decorations be outside the screen-bounds.
Un-maximizing the default startup file would also move window to the
same over-sized location.
Resolve by clamping the size of new windows to the requested bounds.
Scrolling the mouse wheel fast can generate multiple click-steps
which were ignored by window manager events.
This meant scrolling fast with a trackpad (with "Multi-touch gestures"
disabled) for e.g. would zoom less than the gesture made more slowly.
This macro makes it convenient to define a supported version range for
an interface.
Uncommenting USE_VERBOSE_OLD_IFACE_PRINT prints when newer versions
of an interface are supported by the compositor which Blender could
be updated to support.
This makes it more convenient to bump interface versions as they
become available so bumping multiple versions at once doesn't
cause unexpected changes in behavior as happened with #120587.
Resolves the issue reported in #120587, which occurred when bumping the
supported version of the seat API to 9.
Smooth scrolling values were set in without calling the discrete step
callback. Resolve by calculating discrete values from the:
wl_pointer_listener::axis_value120 handler.
The functional changes from this commit only apply once the version
of the seat API is increased - which isn't part of this commit.
This matches behavior on macOS as well as the property description.
On Wayland, smooth scrolling doesn't use the touchpad API,
so disabling multi-touch gestures doesn't change the behavior as it
does on macOS.
Resolve by converting vertical touch scrolling to mouse-wheel events.
Ensure that the MemHead and MemHeadAligned are such that memory
allocation followed with the head offset keeps the allocation
aligned to at least MEM_MIN_CPP_ALIGNMENT.

The callback to set the relative direction wasn't running because
it required GHOST to request version 9 of the wl_seat_interface.
Natural touchpad events now work for KDE 6 and recent versions
of WLROOTS based compositors, GNOME 46 is uses wl_seat_interface
version 8 which still wont work.
MoltenVK original intent was to let developers work on a mac system developing
for the vulkan eco-system. MoltenVK doesn't support all the features that we
require and would require additional workarounds to be actually supported.
It is not expected that we will release Blender with MoltenVK for this reason.
But it still has value for shader developers to validate shaders on metal and
vulkan on a single platform.

This is a regression since fdc2962beb
The size of state can not be different between CPU and GPU.
This change replaces compile-time condition with a kernel feature
check, which solves the render regression on AMD Metal. It also
minimizes the state size on other GPUs when Light Tree is disabled.

Ever since commit [1], `use_metalrt_by_default` will be True
if the GPU being used is not a M1 or M2 based system.
The intention of this was to enable MetalRT by default for
M3 and newer devices that have hardware for ray traversal.
However the side effect of this change was that all AMD GPUs would
have `use_metalrt_by_default` set to True. Which appears to be the
main culprit causing crashes on older AMD GPUs in #120126.
Since these GPUs don't support MetalRT.
This commit fixes this issue by only setting
`use_metalrt_by_default` to True if the GPU is not M1 or M2 based,
and the GPU is Apple Silicon based. Which equates to M3 or newer.
Which is the original intent of this code.
This resolves the issue where AMD GPUs were being told to use MetalRT
by default, when they shouldn't be.

The issue was caused by the special code in Cycles which clears object
caches when it thinks they are not needed. We should not free caches of
grease pencils because it is needed later by a separate render engine.

This is a regression in 4.1, caused by 36e603c430.
For unbiased MIS weight in light tree, we should use sd->N for
mis_origin_n, since sc->N is not available in NEE.
The change also makes it so we do not sample lights below sd->N even
when bump map correction is disabled. This diverges from the original
idea of giving full control to artists, but ensures the internal math
is happy.

We call UpdateWindow very early in our window creation, before we get
an openGl surface and before our message queue is ready. This results
in WM_ACTIVATE, WM_SIZE, WM_MOVE, and WM_PAINT messages sent to us
at a time when GetMessageTime() returns zero. This makes our event
message times have a gap between the fourth and fifth messages, equal
to the time since system start. There is no downside to not calling
this at this time.
