This patch puts threads that render the same pixel closer together,
as opposed to threads that render the same sample. Thus threads
within a warp are more coherent in memory access and control flow,
leading to performance improvements.
Example benchmarks on a Quadro RTX4000 (WDDM) on Windows 10:
Koro: 4:23 -> 3:46
BMW: 1:18 -> 1:25
Barbershop Interior: 17:52 -> 14:55
Classroom: 4:37 -> 3:45
Performance differences on OpenCL/AMD were hit and miss, some scenes
became faster, others lost significantly. Therefore, this is kept as
CUDA only change for now.
Stupid mistake in previous 'fixing' commit, I put the call computing
extra required source cddata masks into the callback used to get
destination (current object) cddata masks...
The NODE_GROUP_LEVEL of the Geometry node should be bumped to 1
when Backface is connected. Backface uses `NODE_LIGHT_PATH` that
is part of NODE_GROUP_LEVEL1, the rest of the geometry ndoe is
NODE_GROUP_LEVEL_0.
For full keymaps, ensure keymap items are lists to allow predictable
manipulation at runtime.
When calling `keymap_init_from_data` directly, allow any sequence type
to allow tools to define their keymaps as tuples.
In this case, the generic vertex attribute is {0,0,0,1}. So we look for
this case.
This fixes black text objects with a normal map applied. Also this could
help porting sculpt mode drawing to Eevee without supporting normal
mapping.
Note that will just fix black meshes due to T61870 but objects will not
show their normal map. So it's not a fix for this issue.
Left and right aligned regions get hidden when there is not enough space,
and the main center region was empty. Now remove the left region and put
its contents in the center region, so that it always remains.
Draw manager was checking for particles being enabled in viewport, but
actual evaluation was happening for render. Now the check in draw manager
properly follows current evaluation mode.
Additionally, de-duplicated some check, by moving everything needed to
a single place.
Annoying part is the const-cast, that could be cleaned up later by
modifying some underlying functions.
The core was hooking up relation to a wrong operation, in an
attempt to cause proper full update of the pose (since there
is no intermediate state stored anywhere). This is now done
as a part of flush_handle_component_node(), so can properly
route more granular relation.
This fixes the crash which was caused by an access of partially
evaluated data by solving the fake cycle. However, if there
is a real cycle involved the code will still not survive, but
this is more generic issue (which also includes modifiers
for meshes and curves).

Before the cursor was only visible after the cursor moves over side areas, but not in viewport area.
Now, as soon the drawing is completed, the cursor is reset in order to get again the icon in the viewport.
The option can be changed in the Preferences
in `Interface -> Editors -> Factor Display Type`.

Use dedicated flag to tag animation just for copy-on-write synchronization,
which makes it so copies of the original data blocks gets in sync with the
original ID. This will not flush the animation update to all objects which
depend on that animation.
If such flush is required, use ID_RECALC_ANIMATION.

When having loops in a kinematic chain and also a IK constrain,
the solve_cycle function removes graph relations necessary to ensure
the cleanup operation was running at the very end.
Due to his Blender was crashing when some operations (the bone
constraints) accessed a pointer that was already freed.
Solved by adding more relations between crucial nodes.
Broke uv-sphere creation, further it might be a problem
for script authors expecting matching edge order for duplicated content.
Now only apply this when duplicating via the operator.
