This change adds cryptomatte render passes to EEVEE-Next. Due to the upcoming viewport
compositor we also improved cryptomatte so it will be real-time. This also allows viewing
the cryptomatte passes in the viewport directly.
{F13482749}
A surface shader would store any active cryptomatte layer to a texture. Object hash is stored
as R, Asset hash as G and Material hash as B. Hashes are only calculated when the cryptomatte
layer is active to reduce any unneeded work.
During film accumulation the hashes are separated and stored in a texture array that matches
the cryptomatte standard. For the real-time use case sorting is skipped. For final rendering
the samples are sorted and normalized.
NOTE: Eventually we should also do sample normalization in the viewport in order to extract the correct
mask when using the viewport compositor.

A regression since ac20970bc2
The issue was caused by depsgraph clearing all id->recalc flags
wrongly assuming that all IDs are fully evaluated.
This change makes it so the depsgraph becomes aware of possibly
incompletely evaluated IDs.

Additionally, just stick to a pure error stating. Such messages
are aimed for developers and it is rather implied that oneAPI
rendering will be disabled.
A continuation of previous fix for malloc hooks which got removed
from the new glibc library.
The pre-compiled jemalloc has definitions which interpose hooks
in glibc leading to linking errors with multiple hook definitions.
A simple fix is to skip doing the workaround when using jemalloc
from pre-compiled libraries.
This will likely be revisited in the future, but for now it is
important to fix compilation errors for developers.
This refactors the geometry nodes evaluation system. No changes for the
user are expected. At a high level the goals are:
* Support using geometry nodes outside of the geometry nodes modifier.
* Support using the evaluator infrastructure for other purposes like field evaluation.
* Support more nodes, especially when many of them are disabled behind switch nodes.
* Support doing preprocessing on node groups.
For more details see T98492.
There are fairly detailed comments in the code, but here is a high level overview
for how it works now:
* There is a new "lazy-function" system. It is similar in spirit to the multi-function
system but with different goals. Instead of optimizing throughput for highly
parallelizable work, this system is designed to compute only the data that is actually
necessary. What data is necessary can be determined dynamically during evaluation.
Many lazy-functions can be composed in a graph to form a new lazy-function, which can
again be used in a graph etc.
* Each geometry node group is converted into a lazy-function graph prior to evaluation.
To evaluate geometry nodes, one then just has to evaluate that graph. Node groups are
no longer inlined into their parents.
Next steps for the evaluation system is to reduce the use of threads in some situations
to avoid overhead. Many small node groups don't benefit from multi-threading at all.
This is much easier to do now because not everything has to be inlined in one huge
node tree anymore.

Since this was added, Linux libraries have been included in `../lib/`.
This made `make bpy` on Linux install the `bpy` module into the bundled
SVN libraries which isn't very useful.
Now leave WITH_INSTALL_PORTABLE unset (defaulting to ON).
Python developers may reference their systems Python and disable the
option if they wish for a system-wide module installation.
As portable is already the default, setting it meant using the lite
configuration would always reset the value if was intentionally changed.
This was also inconsistent as other configurations left this unset.
This was a kind of "lite" target, disabling options such as FFMPEG and
ALEMBIC which may be useful to read/write data from the Python module.
Now fewer options have been changed.
The following options are now disabled:
- Audio support (to prevent audio devices being initialized on startup).
- Input device support such as NDOF and IME as there is no GUI.
- Blender thumbnail extraction as it's not installed as part of
the Python module.
Instead of attempting to predict what is useful to enable when building
as a Python module, developers can mix combine options e.g.
"make bpy release" or "make bpy lite".
This makes the NLA_OT_actionclip_add operation (Shift+A while mousing
over the NLA strips area) fail on invocation if no tracks are active.
This stops the annoyance of using the Shift+A menu to select an action
to add, but only getting the error after you select an action.

The pre-processor blocks contained un-balanced braces, causing a syntax
error when building with WAYLAND but not X11.
Use the same number of opening & closing braces in each pre-processor
block so changes aren't as likely to break other platforms.
Also assert when unexpected states are reached.
Fix error and warnings introduced in commit 8851790dd7. Include
unistd.h for close() on Non-Windows OSs. Calm warnings about unused
argument. Return full size of image file to caller.

When there was only a single material assigned to the mesh, the material

corresponding data layers and using their values for computations.
Avoiding that should increase performance in many operations that
would otherwise have to read, write, or propagate these values.
It also means decreased memory usage-- not just for sculpt mode
but for any mesh that was in sculpt mode. Previously the mask, face set,
and hide status layers were *always* allocated by sculpt mode.
Here are a few basic tests when masking and face sets are not used:
| Test | Before | After |
| Subsurf Modifier | 148 ms | 126 ms |
| Sculpt Overlay Extraction | 24 ms every redraw | 0 ms |
| Memory usage | 252 MB | 236 MB |
I wouldn't expect any difference when they are used though.
The code changes are mostly just making sculpt features safe for when
the layers aren't stored, and some changes to the conversion to and
from the hide layers. Use of the ".hide_poly" attribute replaces testing
whether face sets are negative in many places.

sculpt_update_object now auto-creates a CD_MDISPS layer
if missing. Note that it is possible for the depsgraph
to provide a multires ccg context without a CD_MDISPS.
This causes a PBVH_GRIDS pbvh to be built instead of
falling back to PBVH_FACES, which is why this bug happens
(of course falling back to PBVH_FACES would still be a bug).
These changes were implemented by Sonny Campbell.
Fixed the first issue by freeing the operator customdata when the import
is cancelled.
Fixed the second issue by using a character array instead of allocating
new memory for the prim_path_mask.

When resizing mesh and curves attribute storage, avoid initializing the
new memory for basic types. Also, avoid skipping "no free" layers; all
layers should be reallocated to the new size since they may be accessed.
The semantics introduced in 25237d2625 are essential for this
change, because otherwise we don't have a way to construct non-trivial
types in the new memory.
In a basic test of the extrude node, I observed a performance
improvement of about 30%, from 55ms to 42ms.

Generally we don't want to do per-element operations on these spans
because of the overhead of the runtime type system, but these operations
on the whole span avoid ugly pointer arithmetic in other areas.
The bug was contained in BKE/intern/nla.c, where the wrong macro was
used as the minimum frame value. Instead of `MINAFRAMEF`, `MINFRAMEF`
was used (the former is around -10k, the latter is 0, both fp32).

Starting from GLibC 2.34, deprecated `__malloc_hook` & co. have been
removed from headers, while still present in the shared library itself.
This means that it is no more possible to build Blender with USD 22.03
on recent linux systems.
While USD 22.08 has a fix to this issue, it is unlikely to be upgraded
for Blender 3.4, and definitely not for Blender 3.3.
This commit ensures Blender can build with USD 22.03 and glibc >= 2.34.
