Fix T57138: Cycles CMJ failing with viewport samples set to 0.

Can't use INT_MAX, CMJ runs into precision/overflow issues before that.

Fix T58793: Volumetric Clouds in Eevee not working | MacOs

Fix missing attribute in vertex shader. Theses are optimized out if using
volumetric shader but on MacOS they seems to be needed.

Fix T58610: EEVEE: camera motion blur renders only one viewport sample

This fix saves the camera matrices in order to not call
BKE_animsys_evaluate_animdata during each draw loop. This function tags
the view as dirty even if the camera does not move.
This effectivly, avoids the constant reset of TAA.

Fix T58694 Eevee: Wrong result when using normal map and face is flipped

Fix T62551: Limited Hair editing (no grab, scale, rotate)

This is actually re-introduced T59963 which got broken by 6752022310b.
Use less obscure recalc flag now.

Fix T61300: First letter truncated

The main problem was that the character `J` has "negative kerning".
It was cut off because it started outside of the clipping rectangle.

Fix T62321: Crash on motion tracking when dopesheet open and deleting track

Need to ensure all dopesheet are properly tagged for update.

The tricky part here is that due to the animation we need to keep
movie clips covered by copy-on-write, but the interface uses an
original clip to draw dopesheet.

Use same idea of an active dependency graph as is done in other
similar cases.

GPencil: Change Brush defaults for Block and Marker

Still pending the change in default 2D template.

Changes reviewed by @pepeland and @mendio

Fix some unreported issues with image sequence updates, clean code.

Lamp and world nodes were missing, nested node trees were updated twice,
remove some legacy code.

Fix T61937: image sequences not updating in workbench display mode.

Need to pass the image user along to get the frame number.

Cycles: Improved thread order for better CUDA performance.

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.

Fix T62528: data transfer modifier error.

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...

Fix T62145: Geometry.Backface Node Renders Black

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.

Fix separators use within tool groups

Keymap: tweak keymap loading type checks

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.

Cleanup: unused imports

Keymap: remove select linked deselect

This didn't do anything useful (always de-selected all).

Cleanup: match WorkSpace and WorkSpaceTool capitalization
