This is an implementation that is about 1.5-2.1 times faster. It gives a result
that is on average 6° different from the old implementation. The difference is
because normals (Ng, N, N') are not selected to be coplanar, but instead
reflection R is lifted the least amount and the N' is computed as a bisector.

Static initialization order was not guaranteed to be correct for node base
types. Now wrap all initialization in accessor functions to ensure the order
is correct.
Did not cause any known bug on Linux/macOS/Windows, but showed up on this
platform.
The issue was caused by a prediction algorithm detecting tracking the
wrong way. Solved by passing tracking direction explicitly, so that
prediction will always happen correctly regardless of the state of the
Tracks context.
This type, CacheLookupResult, holds the data for the current time, or an
explanation as to why no data is available (already loaded, or simply
nothing available). This is useful to document the behavior of the code
but also, in future changes, to respond appropriately for missing data.
Inside of the procedural, instances are AlembicObjects which point to
the AlembicObject that they instance.
In Alembic, an instance is an untyped Object pointing to the original
(instanced) one through its source path. During the archive traversal we
detect such instances and, only if the instanced object is asked to be
rendered, set the instance's AlembicObject to point to the original's
AlembicObject.
Cycles Object Nodes are created for each AlembicObject, but only for
non-instances are Geometries created, which are then shared between
Object Nodes. It is supposed, and expected, that all instances share the
same shaders, which will be set to be the ones found on the original
object.
As for caching, the data cache for an AlembicObject is only valid for
non-instances and should not be read to or from as it is implicitly
shared.
This will help support instancing as cache building is now decoupled
from the logic to update the Nodes' sockets as data (and cache) will
need to be shared by different Geometries somehow, and also simplify
implementing different data caching methods by centralizing this
operation.
We need to explicitely tag the Attribute and AttributeSet as modified if
we change or add/remove data. This is more of a bandaid until attributes
handling is refactored to be able to reuse routines from the Attribute
API.
This patch changes the `MEM_DEVICE_ONLY` type to only allocate on the device and fail if
that is not possible anymore because out-of-memory (since OptiX acceleration structures may
not be allocated in host memory). It also fixes high peak memory usage during OptiX
acceleration structure building.

The Blender/Cycles XYZ color space has a D65 white point instead of E, and
this was not correctly accounted for both in the OpenColor config reading code
and the bundled config.
This meant that since the OpenColorIO v2 upgrade, the Linear ACES color space
was not working correctly, and other OpenColorIO configs defining
aces_interchange were not interpreted correctly.
Something in this update broke the floor() function in CUDA, instead use
floorf() like we do everywhere else in the kernel code. Thanks to Ray
Molenkamp for identifying the solution.
The missing update has two sources:
The TimeSampling used for looking up transformations in the cache was
uninitialized. To fix this, simply use the TimeSampling from the last
transformation in the hierarchy (that is the object's parent), which
should also contain the time information for all of its parents.
The objects are not tagged for update when their trasformations change.
Is based on Google style which was used in the Libmv project before,
but is now consistently applied for the sources of the library itself
and to C-API. With some time C-API will likely be removed, and it
makes it easier to make it follow Libmv style, hence the diversion
from Blender's style.
There are quite some exceptions (clang-format off) in the code around
Eigen matrix initialization. It is rather annoying, and there could be
some neat way to make initialization readable without such exception.
Could be some places where loss of readability in matrix initialization
got lost as the change is quite big. If this has happened it is easier
to address readability once actually working on the code.
This change allowed to spot some missing header guards, so that's nice.
Doing it in bundled version, as the upstream library needs to have some
of the recent development ported over from bundle to upstream.
There should be no functional changes.
Because of D10469 we can now not force child windows onto parent's monitor and allow them to go where they wish.

Before this change messages of ERROR and above were printed.
This change makes it so LOG(INFO), LOG(WARNING), LOG(ERROR)
and LOG(FATAL) will be printed to the console by default
(without --debug-libmv and --debug-cycles).
On a user level nothing is changed because neither INFO nor
WARNING severity are used in our codebase. For developers this
change allows to use LOG(INFO) to print relevant for debugging
information. Bering able to see WARNING messages is also nice,
since those are not related to debugging, but are about some
detected "bad" state.
After this change the LOG(INFO) is really treated as a printf.
Why not to use printf to begin with? Because it is often more
annoying to print non-scalar types. Why not to use cout? Just
a convenience, so that all type of logging is handled in the
same way. When one is familiar with Glog used in the area, it
is easy to use same utilities during development. Also, it is
easy to change LOG(INFO) to VLOG(2) when development is done
and one wants to keep the log print but make it only appear
when using special verbosity flags.
The initial reason why default severity was set to maximum
possible value is because of misuse of VLOG with verbosity
level 0, which is the same as LOG(INFO). This is also why
back in the days --debug-libmv was introduced.
Now there is some redundancy between --debug-libmv, --debug-cyles
and --verbose, but changes in their meaning will cause user
level side effects.

Usage of LOG(INFO) actually went against own guidelines in the
logging.h: the INFO is for messages which are to be printed
regardless of debug/verbosity settings.
This issue seems to be caused by the reallocation flag not being set on
the device shader data array so it was never updated on the GPU although
the host memory was modified.
This bumps OSL to 1.11.10.0. OSL Has a new build time
dependency: Clang, and more importantly it expects
clang and llvm to share a library folder, which it
previously for us did not.
This patch changes:
-OSL Update to 1.11.10.0
-refactor the llvm/clang/clang-tools-extra builds into the llvm
build using the llvm-project tarball for building that has all
of the subprojects in it.
-update ispc/openmp builds since clang no longer its own dependency
and they have to depend on the llvm build now.
-Update the windows builder to use the 64 bit host tools since it
ran out of ram linking clang
-Since OSL now needs clang to link successfully a findclang.cmake
has been provided for linux/OSX

m_tabletInRange is no longer set for Wintab after 2e81f2c01a
reverted Wintab changes. This reverts most button processing to
behavior present in 2.91.2.
Left in place is a bugfix for Windows Ink: button events while a
Windows Ink pen is in range should still be processed. Events processed
by Windows Ink and not passed to DefWindowProc do not create WM_*BUTTON
events, but button events from e.g. tablet pad express keys do create
WM_*BUTTON events and should be handled.
Windows mouse history function GetMouesMovePointsEx has well documented
bugs where it receives and returns 32 bit screen coordinates, but
internally truncates to unsigned 16 bits. For mouse (relative position)
input this is not a problem as motion events and the resulting screen
coordinates reliably fit within 16 bit precision.
For tablets (absolute position) the 16 bit truncation results in
corrupt history when tablet drivers use mouse_event or SendInput from
the Windows API to move the mouse cursor. Both of these functions take
absolute mouse position as singed 32 bit value on the range of 0-65535
(or 0x0-0xFFFF) inclusive. Values larger than 0x7FFF (the largest
signed 16 bit value) are reliably corrupt when retrieved from
GetMouesMovePointsEx history. This is true regardless of whether mouse
history is retrieved using display resolution (GMMP_USE_DISPLAY_POINTS)
or high resolution points (GMMP_USE_HIGH_RESOLUTION_POINTS), the latter
of which should return points in range 0-65535.
