This patch adds a new Cycles device with similar functionality to the
existing GPU devices. Kernel compilation and runtime interaction happen
via oneAPI DPC++ compiler and SYCL API.
This implementation is primarly focusing on Intel® Arc™ GPUs and other
future Intel GPUs. The first supported drivers are 101.1660 on Windows
and 22.10.22597 on Linux.
The necessary tools for compilation are:
- A SYCL compiler such as oneAPI DPC++ compiler or
https://github.com/intel/llvm
- Intel® oneAPI Level Zero which is used for low level device queries:
https://github.com/oneapi-src/level-zero
- To optionally generate prebuilt graphics binaries: Intel® Graphics
Compiler All are included in Linux precompiled libraries on svn:
https://svn.blender.org/svnroot/bf-blender/trunk/lib The same goes for
Windows precompiled binaries but for the graphics compiler, available
as "Intel® Graphics Offline Compiler for OpenCL™ Code" from
https://www.intel.com/content/www/us/en/developer/articles/tool/oneapi-standalone-components.html,
for which path can be set as OCLOC_INSTALL_DIR.
Being based on the open SYCL standard, this implementation could also be
extended to run on other compatible non-Intel hardware in the future.

terminateMantaflow was never called, this leak is more of a technicality
since it's only called on exit.
Also make Py_Initialize/Py_Finalize optional in Pd:setup/finalize
as it caused Blender to crash, finalizing Python twice.
Add a patch to extern/mantaflow to keep track of changes in Blender
from up-stream.
This could result in wrong skipping of SVM nodes in the graph. Now make the
logic consistent with the clamping in the OSL implementation and constant
folding.
Thanks to Christophe Hery for finding the problem and providing the fix.
Enables Vega and Vega II GPUs as well as Vega APU, using changes in HIP code
to support 64-bit waves and a new HIP SDK version.
Tested with Radeon WX9100, Radeon VII GPUs and Ryzen 7 PRO 5850U with Radeon
Graphics APU.

Instead, create keyboard two states when the keyboard layout is set
(one with & one without num-lock pressed).
This avoids key-press lookups having to check if num-lock exists and
setting the keyboard state for key press & release events.
No functional changes.
Accessing the symbols for keys with no modifiers & num-lock enabled
has unintended consequences for some keyboard layouts that use this
to switch layers.
Resolve by restricting num-locked lookups to keys typically toggled
with num-lock (key-pad home, page up/down ... etc).
Implement scan-code fallback when the scan-code used for AccentGrave
on US keyboards doesn't map to a key known to GHOST.
Without this, shortcuts that use AccentGrave are inaccessible and the
key does nothing.
This matches functionality from X11, see [0].

Add WITH_GHOST_WAYLAND_DBUS option, so Blender can be built without
DBUS support. Currently it's only used to access the cursor theme.
Without this the "default" cursors are used instead.
Disabling this since it adds an additional dependency for a minor gain
in functionality, with the benefit of removing a library requirement.
There is also a problem where Blender hangs on startup for ~5 seconds
when DBUS isn't running. Eventually it would be good to be able to avoid
this problem without a build option.
For Wayland the mouse & tablet are separate devices with their
own location, button-pressed state and focused window.
Split internal state storage so they're separate.
Also track mouse button press/release state without needing focused
windows.
If there is an error we should stop rendering, instead of finishing with a
wrong render result or reporting a wrong benchmark time.

This implements client-side window decorations for moving and resizing
windows and HiDPI support.
This functionality depends on the external project 'libdecor' that is
currently a build option: WITH_GHOST_WAYLAND_LIBDECOR.

Manta flow used the `__main__` namespace which it was executed in,
this caused a bug when calculating fluid from Python, which clears
it's `__main__` name-space after execution.
This caused Manta-flows name space to be cleared too.
Resolve this by creating a separate name-space for manta-flow.

As grab already uses it's own virtual coordinates, cursor warping can
be used when grab is enabled.
Currently nothing depends on this however it could be useful in future.
This change helps decrease Intel GPU binaries compile time by 5-10
minutes without impacting other backends.

This patch unifies the names of math functions for different data types and uses
overloading instead. The goal is to make it possible to swap out all the float3
variables containing RGB data with something else, with as few as possible
changes to the code. It's a requirement for future spectral rendering patches.

- Respect modifier keys (Shift press/release didn't change the case).
- Changing modifiers resets the timer instead of canceling key-repeat.
- Releasing keys (besides the key being repeated) resets the timer
instead of canceling key repeat.
This makes key-repeat behave the same way as GTK & WIN32 text input.
This patch suffixes Apple GPU device names with `(GPU - # cores)` so that variant GPUs with the same chipset can be distinguished. Currently benchmark scores for these M1 family GPUs are being incorrectly merged:
- M1: 7 or 8 cores
- M1 Pro: 14 or 16 cores
- M1 Max: 24 or 32 cores
- M1 Ultra: 48 or 64 cores

Instead of providing our own names for wayland headers, use the filename
component as the basis for the header names. This matches most reference
documentation for Wayland.
Also generate client protocols into a sub-directory `libwayland`,
instead of generating headers into the ghost directory. Making the
include path more specific & makes it easier to differentiate generated
headers from other build files.
* Rename "texture" to "data array". This has not used textures for a long time,
there are just global memory arrays now. (On old CUDA GPUs there was a cache
for textures but not global memory, so we used to put all data in textures.)
* For CUDA and HIP, put globals in KernelParams struct like other devices.
* Drop __ prefix for data array names, no possibility for naming conflict now that
these are in a struct.
Changing the cursor would intermittently close Blender's window
(without crashing).
This happened because the size of a cursor must be the a multiple of the
scale, for themed cursor this is always true but with custom cursors
it's not.
Separate theme scale from custom cursor scale to avoid this bug.
In the future we can support Hi-DPI custom cursors, for now they're
scale is always set to 1.
- Support showing & hiding the cursor without setting the buffer,
needed to switch between software and hardware cursor.
- Track the state of the software/hardware cursor.
This resolves glitches switching between cursors sometimes hiding the
cursor.
getMainDisplayDimensions return values were scaled by the UI-scale,
instead of returning pixel values.
Also correct an error accessing the rotated monitor size,
which happened to be harmless as the value isn't used at the moment.
Add a method to access the custom cursor from GHOST which is used
for drawing a software cursor. This means the knife tools cursor now
work as expected.
Although non-custom cursors are still not supported.
