MTLContext provides functionality for command encoding, binding management and graphics device management. MTLImmediate provides simple draw enablement with dynamically encoded data. These draws utilise temporary scratch buffer memory to provide minimal bandwidth overhead during workload submission.
This patch also contains empty placeholders for MTLBatch and MTLDrawList to enable testing of first pixels on-screen without failure.
The Metal API also requires access to the GHOST_Context to ensure the same pre-initialized Metal GPU device is used by the viewport. Given the explicit nature of Metal, explicit control is also needed over presentation, to ensure correct work scheduling and rendering pipeline state.

From the nodes' description: "Retrieve the object that contains
the geometry nodes modifier currently being executed". This was
discussed in the most recent geometry nodes module meeting.
Because the node allows you to retrieve the position of the modifier
object, it has to add a depsgraph relation to object transform.
Expect that modifiers will be reevaluated when moving the object.
In the future, better static analysis of node trees could make this
check smarter.

Now explicitly including math.h first before #defining funcitons.
This avoids undefined behavior and improves compatibility with
different SYCL compilers and backends.
In UV editor, previously unable to see grid and image at same time.

The BMesh selection virtual array was empty. There are a few different
places we could add an "empty" check here, but at the top of the
function is the simplest for now.
Similar to e5a7470638, the tree currently being edited should be
used for polling and other tests, rather than the node tree at the root
of the node editor's path.
This was caused by the vertical/horizontal clasification being done in
NDC space which wasn't respecting the Aspect ratio.
Multiplying the test vector by the target size fixes the issue.
The typed "lookup_or_add_for_write_only" function is meant to do the
same thing as the non-typed version of the function. Instead, it still
initialized values of new attribute arrays, which isn't meant to happen.
Missed in 4c91c24bc7.
I also had to correct one place that used the "write_only"
function but didn't intialize all values.
I didn't observe this issue in practice, but since the write_only
version of the attribute API isn't meant to initialize trivial types,
theoretically this could be a problem if the attribute is created
halfway through converting the BMesh to a Mesh.
The BM_mesh_bm_to_me_for_eval() cal be called on the same BMesh
from multiple threads. This adds a restriction that this function
should not modify the BMesh. This started to be violated quite
madly during the generic attributes changes.
This change makes it so that the BMesh is not modified.
The code looks less functional-like, but it solves the threading
conflict.
Ideally the BMesh will be const in the function but doing it now
is a bit tricky due to the other APIs.
The repro case for the crash is a bit tricky to reproduce from
scratch. For those who has access to the Heis production repo
/pro/lib/char/pack_bot/pack_bot.blend file can be used. Simply
add loop to "GEO-leg.R" object and use bevel operator on the
new loop.
There is still some write of the element indices happening in
this function. In theory those could be removed (together with
the dirty index tag clear) but it leads to obscure crashes in
area far away from this one. I've left it unchanged for now as
on 64bit platforms those assignments should not be causing real
issues.

Base it in an existing building blocks rather than having dedicated
structure for it.
No functional changes is expected, just preparing to make the code
more reusable.
The ID nodes will use the provided component name to maintain
the map-based storage, while the component node itself could
override the empty name with a type name.
This lead to situations when it is not possible to lookup
the operation from its owner parameters.
Make it so find type of methods receive const pointers and do not
modify graph topology.
The latter was violated in the find_operation() which could have
created an empty component. This is not intended behavior.
No functional changes is expected.
I'm adding some asset APIs/types in C++ that the file-listing code would
use. I prefer porting this code to C++ over adding a C-API for the asset
code.
Includes some minor cleanups that shouldn't change behavior, like using
`MEM_new()`/`MEM_cnew()`, C++ style C-library includes,
`LISTBASE_FOREACH()`, removing unnecessary typedefs, etc.
This functionality was present until Blender 2.80. Basically it adds back the
"+" and "-" buttons in the file browser when it stores an output filepath.
This is useful for someone rendering multiple versions of an animation (or a
composition) to compare.
At the moment this is used for the render output, and the File Output node in
the compositor.

Sorry, this was working before I rebased. I believe the warning was
fixed and the rebase still applied.
The commit as it was introduced building problems
This reverts commit ae21319d7f.
This was used in early node based particle system development
but is not used anymore. The code also didn't match the standards
of other data structures in blenlib.
Initializing the sys.path on startup attempted to add subdirectories
of {BLENDER_SYSTEM_SCRIPTS}:
- ./modules/modules
- ./modules/startup
As the directories aren't expected to exist there is no need to add them.
Also improved comments for path searching logic.
05952aa94d modified this area incorrectly, transforming
vertices outside of the mesh. That would have been fine, but the mesh
is used to retrieve the bounding box. Instead just avoid duplicating the
positions and normals completely, and avoid using referenced layers
just to be extra safe.
Even meshes without any faces must have MPoly and MLoop layers, etc.
This caused a crash in the extrude node when the edit mesh had no faces
(see T101208). Issue with f94130c94b.
In D10241, both NodeItems for NodeGroupInput and NodeGroupOutput in the
were moved from their categories into the 'node_group_items' generator.
As the NodeItem.poll() is called by the NodeCategory class and not by
the NodeItem class, the poll functions associated with those NodeItems
were never called. This should correct that.
