Fix crash when make proxy failed to assign a proxy

Fix crash setting the brush with the current brush was unset

Fix crash closing a window in background mode

Cleanup: use doxy sections & add missing sections

Fix T74417: Freestyle render removes image texture users

This simplifies freestyle render pipeline integration so we don't have to do
much manual ID user management at all. The complexity here was legacy from
Blender Internal.

Based on fix provided by Sybren A. St�vl.

Fix T74711: tiling brush option in image editor not working anymore

This makes it work again at least for the non-UDIM case. For UDIM it's not
great still but I'll consider that a known limitation. A proper solution is
probably to find the closest tile at the start of the stroke and then only
paint in that one tile for the rest of the stroke.

UI: rename image source Tiled to UDIM Tiles for easier discovery

Fix T75090: crash with old NVIDIA drivers after overlay refactor

Work around GLSL compiler bug with backslash in preprocessor macros.

GPencil: Fix unreported Threshold parameter visible in wrong context

The threshold only must be vsisible in Segment mode.

GPencil: Fix unreported missing parameter for Cutter tool

Fix error after recent change when WITH_INTERNATIONAL=OFF

Always need to install font files now.

Cleanup: typo in print

UI: remove non-unicode font and simplify default font loading code

There is no need to have another font embedded in the Blender executable, we
can assume the bundled font exists. In the future we may provide a fallback
if the font specified by the user in the preferences is missing a character,
but that can use our bundled international font.

UI: always use international font

This means Blender can display more text correctly without having to enable
user interface translation. Previously the quality of the font was lower,
but that has been fixed now.

The font files have now been ungzipped, which results in faster file loading
as Freetype can read only the parts of the file that it needs. Blender download
size should not increase since the release package is compressed.

This includes improvements for Cyrillic characters from the latest DejaVu
Sans fonts from D6960, contributed by Harley Acheson. Fixes T74097.

Cycles: limit number of processes compiling OpenCL kernel based on memory

The numbers here can probably be tweaked to be better, but it's hard to
predict and this should at least avoid excessive memory swapping.

Fixes T57064.

Fix VR viewer offset on session start with no positional tracking

The current viewer pose position as determined by the OpenXR runtime
would be applied as offset. This offset should however only be set when
toggling the positional tracking while the session already runs.

Fluid: Small fix for secondary particles

Small tweak to ensure index will not run out of bounds during secondary particle computation.

Alpha hash support for hair in EEvee

This patch adds support for alpha hash for hair rendering in EEvee. Here's a comparison of with alpha hashing:

And no alpha hashing:

{F7588615}

Note that this needs "soft shadows" enabled, otherwise shadows will be noisy; here's a render with soft shadows disabled:
